COMPANY PROFILE / Solid-State Battery
BMW
— Does not manufacture batteries, instead invests in startups and brings in only the prototype lines to its own production
The mention of BMW with solid-state batteries is due to American startupsSolid Powerand From 2016, it was assembled, and by 2021, it was also invested in, In May 2025, a large solid-state battery cell was actually installed on the BMW i7 technology demonstrator and drivenfrom here. However, BMW itself does not have mass production equipment for battery cells, and what is located in the Pulsdorf facility isa development test line for research and developmentis.

Companies working on solid-state batteriesAutomotive manufacturers, battery manufacturers, and startupsare divided into three types. BMW is one of theseAutomotive manufacturersHowever, unlike Toyota and Honda, which manufacture batteries internally, they invest in startups and access technology through joint development agreements and research and development licenses.takes this form fact. This difference is important. In-house type can be developed at a speed decided solely by the company’s judgment, but The company’s plans are constrained by the progress of the other party. In fact, BMW announced in October 2025Samsung SDIto have reorganized into a three-company structure that includes a startup that makes electrolytes and a battery manufacturer that can mass-produce cells and an automobile manufacturer that installs them in cars by tying these entities together under one contract. BMW is at the bottom of this arrangement.bottom.
2. Regarding logo and company name display
Note on representation: The company name is Bayerische Motoren Werke Aktiengesellschaft(BMW AG). The parties to the contract for solid-state batteries were different depending on the document.BMW AGorBMW of North America, LLCor BMW Holding B.V.(It was a Dutch holding company with investments). In this article, it is important that the main subject of investment and joint development are separated, so we will write the corporate names separately where necessary.

| BEV sales volume | 442,056 units (2025, +3.6% from the previous year). Represents 17.9% of total sales. |
The number above isfor the entire company.It does not represent the scale of business for solid-state batteries. BMW has not disclosed any investment amounts, dedicated personnel numbers, or sales figures related to solid-state batteries. Unconfirmed / Future. Research and development expenses of 831.9 million euros, including the amount for solid-state batteries is not disclosed. The only clue to measure BMW’s involvement in this field by amount is,the documents submitted by Solid Power, which is an investment target, to the U.S. SECIt is. In the next chapter, I will use it but, the point that the source is disclosed by the other partywill be explicitly stated.
5. Resources invested in solid-state batteries
BMW’s own disclosure is limited to ‘who, when, and what’,and has not provided the amount or number of people. Meanwhile, the invested company Solid Power is a publicly traded U.S. company, sothe amounts received from BMW and BMW’s shareare disclosed in the legal filing documents. This article will present both together.We will always record which disclosure it is referring to.。
| Resource types | The content that has been made public. | Classification |
|---|---|---|
| Investment to the outside (time period) | BMW Holding B.V.which, Solid Power’sSeries B (closed in May 2021)participated. BMW side announced it as ‘a leading investor in the Series B investment round’ (alongside Ford and Volta Energy Technologies) | fact |

In the April 2026 submission, BMW is not listed among the shareholders holding more than 5% | Fact (Solid Power’s disclosure) |
| Investment in external entities (governance) | BMW Holding isDesignated right to appoint one directorandRight to observe the board of directorsDr. Rainer Feurer, BMW’s SVP Corporate Investments, has been a director of Solid Power since May 2021 | Fact (Solid Power’s disclosure) |
| Payment of license fees | As compensation for a research and development exclusive license, BMW paid Solid Power$20 millionto be paid in installments from December 2022 to June 2025 based on milestone achievements | Fact (Solid Power’s disclosure) |
| Purchase of materials | The amount Solid Power received from BMW for the purchase of cell materials and electrolytes in 2025344,000 dollars(Sales recognized by Solid Power were 189,000 dollars) | Fact (Solid Power’s disclosure) |
| company’s facilities | Pulsdorf’s Cell Manufacturing Competence Center (CMCC)based on Solid Power’s research and development license for all-solid-state batteriestrial linewas established. CMCC itself is approximately 170 million euros, approximately 15,000 square meters, and approximately 80 people, butThis number is for the entire CMCC, including Gen6 cylindrical cells | fact |
| person (full-time staff) | number of full-time staff for solid-state batteries | Not disclosed |
| Collaboration with universities and research institutions | cooperative research with universities on solid-state batteries could not be confirmed in BMW’s official documents | Unconfirmed |
BMW paid to Solid Power$20 millionis not the cost of buying a battery or investing, but rather the price for ‘the right to build a prototype line at your own factory’. fact. The license is limited to research and development use only, andCommercial cell production cannot be usedand is explicitly stated. That means BMW bought the right to build its own production line based on the other party’s design drawings and learn by adjusting the process while doing so. to adjust the process while doing so.I bought it.
This isthe most comprehensive form that an equity-based automobile manufacturer can achieveIt is. If you just buy a battery, you will never know where the process is effective. In particular, all-solid-state batteries based on sulfide systems ‘Conditions that cannot be written in the material table’it affects performance. If we don’t touch it ourselves, we can’t verify the competitor’s price in mass production. However, this right isnot usable for mass productionso, ultimately, you will need a separate license agreement or a partner like Samsung SDI that can mass-produce. Unconfirmed / Future。
6. Previous Efforts
| period | incident | Meaning |
|---|---|---|
| 2016 | The relationship between BMW and Solid Power begins (initially focusing on cell research and development) | This field’s automobile manufacturers are quite early |
| July 1, 2017 | We have entered into a joint development agreement (JDA) for solid-state battery cell technology | The parties to the agreement are BMW of North America, LLC |
| May 2021 | BMW Holding B.V. participated in Series B.Simultaneously expand JDA. In BMW’s announcement, ‘receive 100Ah cells from 2022’, ‘demonstration vehicles starting from 2025’, and ‘fully solid-state batteries that can be installed in cars by the end of the 2010s’ | This was a turning point where investment and development agreements were set together |
| Fall of 2022 | in PulsdorfCMCCopened (approximately 170 million euros, approximately 15,000 square meters, approximately 80 people). The initial purpose was to develop Gen6 cylindrical cells for the Neue Klasse | It is not a facility dedicated to fully solid-state batteries |
| January 20, 2023 | expand JDAresearch and development licensehas been added. This allows BMW to establish a prototype line for solid-state batteries at CMCC | payment of $20 million will begin from December 2022 |
| May 20, 2025 | Solid Power’s large solid-state battery cells are installed in the BMW i7 technology demonstrator and are being driven around Munichand announced | the CEO of Solid Power said, ‘This is the first demonstration of a true solid-state battery cell in a vehicle’ |
| October 27, 2025 (Contract signed. Announcement on October 31st) | Samsung SDI joins, forming a three-company structure.A joint evaluation agreement is signed. Solid Power supplies electrolyte, Samsung SDI processes separators/cathodes to create cells, and evaluations are conducted according to performance criteria agreed upon with BMW | added a party that can be mass-produced later |
7. Future Plans
evaluation vehiclegoals aimed for through a joint evaluation contract among three companies
The electric vehicles BMW currently sells haveare not solid-state batteries fact. It uses cylindrical lithium-ion cells of Generation 6 (Gen6) in the Neue Klasse (such as the BMW iX3), BMW isaiming for a 20% increase in volumetric energy density, a maximum 30% reduction in charging time, and a 30% increase in range for the top model. Solid-state batteries are on a different line from this liquid system evolution.is a long-term theme that is running.
Next, all of these are not recorded in BMW’s official materials Unconfirmed / Future。
solid-state batterythe start-up period for mass production／the model(s) to which it will be installed／the company that will handle mass production／ The measured values of cell energy density and capacity (Ah)／Range of the i7 prototype vehicle／ BMW’s investment amount to Solid Power／Investment amounts and personnel for solid-state batteries. The expression ‘solid-state battery that can be used in vehicles by the end of the 2010s’ mentioned in the announcement in 2021has been replaced with a long-term goal without specifying a time period. We do not adopt the production timing based on reports.
8. What does this company aim to achieve with solid-state batteries?
This part includes information that the company has not directly stated.Inferred from primary sources within the scope of what can be read.Along with the basis, I will write it down.
| What can be read | primary information | Classification |
|---|---|---|
| BMW is developing solid-state batteriesand does not intend to make them themselves | The license is explicitly stated to be for research and development only and not for commercial production. Samsung SDI was added as a manufacturer of mass production. | speculation |
| The aim isto maintain the ability to discern technology | They paid $20 million to bring in their own prototype line and are integrating vehicles with i7 entirely on their own | speculation |
| in this technologythey are not betting | We explain it as a good example of ‘technology-open mindset (an open-minded attitude towards technology)’ in our own words. At the same time, we are mass-producing and deploying Gen6 liquid systems. | fact |
| difficult areasI think of it as a pack rather than a cell | Among the items being verified through demonstration tests, we mention cell expansion management, control of operating pressure, and adjustment of temperature conditions | speculation |
| for the near-term all-solid-state batteryfor upper modelsis likely to become | The car chosen for the demonstration was the top-of-the-line sedan i7, and it is not a mass-produced vehicle. | speculation |
| Investment isis also a seat fee for gathering informationbut | has secured the right to appoint one director and the right of observation (as disclosed by Solid Power side) | speculation |
BMW is publicly disclosing items it is observing in its demonstration. Cell expansion management, control of operating pressure, adjustment of temperature conditionsthe three fact. This is allis not a single cell issue but a design challenge for the battery pack. Lithium-sulfide full-solid-state batteries expand and contract with each charge and discharge, so they need to maintain contact at the interfaceContinue applying a constant pressure from the outsideIt is necessary. In liquid-based batteries, you could simply arrange cells in a box and secure them with bolts. For all-solid-state batteries,The mechanism for maintaining pressure itself takes up weight and volumeSo even if the energy density of individual cells increases, it may not be offset by the battery pack.
It is explained that the prototype battery loaded into an i7 ‘inherits the principle of the Gen5 configuration (using square-shaped cells as modules) while combining a new module concept for all-solid-state batteries’. BMW isDefining its work as putting the cells on the car rather than what’s inside the cellsThis can be read Unconfirmed / Future。
9. Mapping of solid-state battery collaborations
10. Technology Approach Used
What BMW is showing isSolid Power’s method. BMW does not design the cell materials themselves fact。
| Item | The content that has been made public. |
|---|---|
| solid electrolyte | sulfide-based. BMW’s press release explicitly mentions ‘sulfide-based’ |
| cell type | large, pure solid-state battery cells(large-format, pure ASSB cells). Solid Power develops and manufactures |
| module configuration | Adopts the principle of Gen5 (integrating square-shaped cells into modules) while combining a new module concept for all-solid-state battery cells |
| Items observed in demonstration | Cell expansion management、Control of operating pressure、Adjustment of temperature conditions |
| Expected effects | Current technology anda highly compact energy storage system with a higher energy density |
| Three-party division of labor | Solid Power supplies solid-state electrolyte for sulfide-based systems → Samsung SDI processes separators/cathodes and manufactures cells → Samsung SDI evaluates performance requirements agreed upon with BMW |
| Disclosure of numerical values | Energy density, capacity (Ah), and rangeAbsolute values for all are undisclosed |
BMW and Solid Power are intentionally「pure ASSB」writing this, there must be a reason. Unconfirmed / Future. Products that claim to be all-solid-state batteries actually have some liquid or gel components left at the interface. If the contact is helped by liquids, performance can be easier to achieve and the requirement for pressure can be relaxed. On the other hand, since flammable organic solvents are left, the safety advantage is reduced, and the meaning of ‘all-solid-state’ also becomes thin.
Putting a ‘pure’ prefix on it is,not using such assistanceis their claim. In that case, the contact at the interface isensured by pressure and powder compaction onlyIt is necessary, and BMW is observing the control of operating pressure in its demonstration. This conclusion is the result. The distinction in this terminology can also be used as a way to distinguish other companies’ statements when reading them. Calculations in this article。
11. The risks this company faces
| Risks | Content | Classification |
|---|---|---|
| Depends on the survival of the other party | Solid Power is an initial public offering startup in the development stage, with its main income coming from the sale of electrolytes and licensing fees. If funding continues, BMW’s plans will also stop. | speculation |
| non-exclusive | Solid Power’s contracts are all non-exclusive and they are working with other companies such as SK On in parallel. There is no guarantee that BMW can precede. | fact |
| cancellation terms exist | Solid Power disclosed that, under the contract amendment in September 2024, BMW will have a right of termination after December 31, 2025, in certain cases. | Fact (Solid Power’s disclosure) |
| the manufacturer for mass production is not determined | Research and development licenses cannot be used for commercial production. The contract with Samsung SDI is currently in the ‘evaluation’ framework | Unconfirmed / Future |
| The target period has been delayed | It had explicitly stated in 2021 that ‘solid-state batteries suitable for use in vehicles by the end of the decade’, but in recent announcements, it has not indicated a specific time frame | speculation |
| Their own liquid-based systems will be competitors | It has achieved an energy density increase of over 20% with Gen6 cylindrical cells, shortened charging time by 30%, and improved range by up to 30%. The conditions for selecting solid-state batteries are also stringent within the company | speculation |
| The test materials are only with the other party | BMW does not disclose any figures or personnel related to solid-state batteries, and must rely on Solid Power’s disclosures. If the other party becomes a non-listed company, information will be cut off. | Unconfirmed / Future |
