Companies working on solid-state batteriesAutomotive manufacturers, battery manufacturers, and startupsare divided into three types. Mercedes-Benz is one of theseAutomotive manufacturersand, we do not make the battery cells themselves. factHowever, unlike BMW, which focuses on one company they invest in two different startups with a different approach (Factorial Energy and ProLogium)in addition, they have their own cell research facility in StuttgarteCampusand they understand the chemical composition and manufacturing process of cells with ‘Mercedes-Benz DNA’, as they explicitly state.they do not make them but understand how to do itThis stance, however, differs from both the in-house production model of Toyota and Honda, as well as the simple procurement model.
2. Regarding logo and company name display
Note on notation: A holding company Mercedes-Benz Group AG(formerly Daimler AG, renamed in 2022) is responsible for the passenger car and van business Mercedes-Benz AG This is a separate legal entity. The design of solid-state battery systems is handled by the British Bracklesworth, which is Mercedes-AMG High Performance Powertrains（HPP）a 100% subsidiary that corresponds to the power unit department in Formula 1. In this article, we will distinguish where each entity is involved.

Factorial Energy and ProLogium are,have different electrolyte systems. Unconfirmed / Future. Factorial’sFESTis explained by the company itself asoperates at room temperature and can use most of the existing cell manufacturing equipment directly. it is said to use solid electrolyte materials and combines with lithium metal anodes. ProLogium isCeramic (oxide-based)has been a company that has focused on this. Mercedes, for example, lists ‘building production capacity in Europe’ as one of the investment goals.
Why do they have two? Solid-state batteries arenot yet decided which electrolyte system will be mass-produced. Calculations in this article. The sulfide-based system is fast and flexible but weak against moisture, while the oxide-based system is stable but hard and difficult to interface with. There are also directions of mixing polymers or halides. If it’s limited to one company, there will be no escape route when that method hits a roadblock in mass production. An investment-type automobile manufacturer betting on multiple options is a rational strategy that contrasts with the approach of an in-house type, which concentrates internal resources on one method.
6. Previous Efforts
| period | incident | Meaning |
|---|---|---|
| November 30, 2021 | Partners with Factorial Energy and invests.Invests in a ‘high two-digit million-dollar scale’.

We do not adopt the reported numbers in this article.
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 |
|---|---|---|
| Cells are not made,mass production is entrusted to partner companiesStrategy | eCampus’s explanation includes ‘The knowledge gained here will be applied to mass production at partner companies’ | fact |
| the goal is more than just the range itself‘Increase by 25% while maintaining the same weight’ | The announced values are all stated under the condition of ‘the same weight and size as standard EQS batteries’ | speculation |
| The first deployment wasthe upper modelis likely to become | The demonstration vehicle was an EQS (top-of-the-line sedan), and the target at that time was also a small series for a limited number of vehicles | speculation |
| I still have not narrowed down to one method | We have invested in both Factorial and ProLogium, which have different electrolyte systems, but there has been no announcement of retracting either investment | speculation |
| The F1 department is being invested inthe brevity of the periodfor this reason | Regarding HPP, ‘leveraging the technology and know-how from F1 for a high-performance automotive project’quickly‘It can be transferred,’ the company explains. | speculation |
| Safety overenergy densityto bring to the forefront | In the public documents, it has consistently been stated that endurance, energy density, and weight reduction come first, with safety being mentioned as an accompanying point | speculation |
The importance of this article is considered based on the number 1,205km. It says ‘The weight and size remain the same as standard EQS batteries, but the usable energy has increased by 25%’in this way factThisChanged only the contents without altering the outer shape of the packageThis is a claim, and if you turn it aroundYou can use the existing car body design as it ismeans.
the most costly aspect in mass production of solid-state batteries is actually not the cell but rebuilding everything from scratch: the body structure, crash safety, cooling, and assembly line Mercedes uses pneumatic actuators to handle pressurization and coolingPassive air coolingsimplified even further, achieving a standard EQS form factor with the same dimensions as the standard EQSreplacing it with a replacementis evident of this intention Unconfirmed / Future. For the same reason, it is consistent that individual cell Wh/kg is not publicly announced. The company wants to sell numbers related to the performance of cells, not. range of a single cartherefore.
9. Mapping of solid-state battery collaborations
10. Technology Approach Used
| Item | The content that has been made public. |
|---|---|
| Cell supplier | United StatesFactorial Energy(Massachusetts, Woburn). The technology isFEST®（Factorial Electrolyte System Technology） |
| Negative electrode | Lithium metal。By using solid electrolytes, it has become possible to adopt them, as explained |
| Electrolyte | Solid electrolyte materials.Operates at room temperature and can reuse many of the existing cell manufacturing facilitiesand Factorial is explained. It does not explicitly state whether it is a sulfide system or an oxide system |
| Method of pressurization | Air pressure actuator. Accommodates the volume changes of cells during charge and discharge to maintain necessary contact pressure |
| Cooling | Passive air cooling(Passive cooling through air flow). This ensures further weight reduction and energy efficiency |
| Published effects | Compared to standard EQS batteries of the same weight and sizeEnergy capacity increases by 25%Range increases by up to 25%. The range of the development vehicle isover 1,000 kmthe forecast |
| in general terms regarding technology | Lithium-metal anode combined with all-solid-state batteries areCells individually have a maximum of 450 Wh/kgThe possibility exists to further increase the weight-energy density (this is not a measured value). |
| comparison subject | The current EQS 450+ has battery capacity118kWhwith a range exceeding 800 km |
Lithium metal anode thickens with each chargeand thins during dischargeThis causes a huge volume change that is incomparable to graphite anodes Unconfirmed / FutureSolid electrolytes cannot follow this movement, so they must be continuously suppressed from the outside or the interface will peel off. On the other hand, with mechanisms like springs or fixed platestightening strongly、 This time, when it expands, excessive pressure will be applied to the electrodes and they will break.
Mercedes choseAir pressure actuatoris, using the elasticity of airThe thickness changes but maintains pressure almost constantThis is the solution Calculations in this article. However, for this, compressors and piping such asBattery partsis required. BMW has listed ‘pressure control’ as a test item, and they are coming up with a different answer to the same problem. The discussion about the mass production of solid-state batteries is shifting from cell performance tables to the structure of the pack.The performance table of the cells is not the focus; rather, it is moving towards the structure of the pack.This can be understood from this point as well.
11. The risks this company faces
| Risks | Content | Classification |
|---|---|---|
| Cannot create cells | We have explicitly stated our policy to entrust mass production to partner companies. The mass production launch of the counterpart may become a constraint. | fact |

| The investment partner is also collaborating with other companies | Stellantis also holds an equal stake (8.1%) in Factorial and has joint development agreements with Hyundai Motor and Kia. It is not proprietary technology for Mercedes | Fact (Disclosure of Investment Holdings) |
| Additional costs of the pressurization mechanism | Pneumatic actuators increase the number of parts beyond just the cell. Cost and reliability on a pack unit basis are not disclosed | speculation |
| Lifetime of lithium metal anode | A structure that repeatedly deposits and dissolves lithium metal, with no published numerical data regarding cycle life | Unconfirmed / Future |
| The target period has some margin | It had stated in 2021 that ‘within five years to a small number of vehicles’, but recently it has expressed as ‘by the end of the 2020s for mass production’ | speculation |
| The company’s revenue environment | Adjusted EBIT for 2025 is 8.2 billion euros, significantly decreased from 13.7 billion euros in the previous year. The investment judgment regarding long-term themes will become stricter | speculation |
| The demonstration is only one unit | The published driving performance is based on long-distance driving by a prototype vehicle using the EQS platform, and the number of vehicles, cumulative distance, and failure rate are not disclosed. | Unconfirmed / Future |
