5. Resources invested in solid-state batteries
As it is a non-listed company, there are no items that can be discussed in terms of price. However,Specific details regarding equipment and technology certification have been publicly announced.。
| Resource types | Content | Classification |
|---|---|---|
| Equipment (core business) | Nashao Pack Factory (completed in 2021), Nashao headquarters baseSpecialized factory for ultra-fast charging power batteries(Completed and put into production in 2023, claims to be the world’s first), battery storage device and system production base (started construction in 2022) | fact |

Gigawatt Energy Research hasa specialized factory for ultra-fast charging batteries cannot be directly reused for solid-state batteries Unconfirmed / Future. The production line for liquid lithium-ion batteries consists ofapplying the electrodes, drying them, rolling or stacking them, and then filling them with electrolyteprocesses as basic steps. For solid-state batteries,No liquidation process exists、a process where solid materials are pressed together at high pressure to adhereis required. Most of the equipment will need to be replaced.
Nevertheless, it is not irrelevant. The technology to evenly coat electrodes and the technology to assemble cells for inspectionare common. Especially for ultra-fast charging batteries, there is a need to create ‘uniform electrodes that do not locally heat up even when high currents are passed’, and this uniformity in creation is also a key point for all-solid-state batteries. The companyCFS is ‘a technology to conquer the triple challenge of ultra-fast charging, high safety, and high energy density’}It is explained that, the logic flows when read in this context.

The ‘Development History’ on the official website isIt is only published until 2024. fact. And thenThe underlined A-sama cell for the full-solid-state battery is not listed with a date in this timeline.. ‘Core technology’ explanation only includes the results. Therefore, this article isunable to determine when Mr. A’s cell was completed. Unconfirmed / Future. Some reports mention a time period, but it is not an official company announcement, so it will not be adopted.

In the media, the production timing and energy density values are mentioned, but the official website does not mention this, and this article will not adopt it。
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 |
|---|---|---|
| All-solid-state batteries alsofocus on ‘fast charging’ as the first selling pointintention | The explanation of CFS states that it ‘overcomes the triple challenges of ultra-fast charging, high safety, and high energy density’, with ultra-fast charging being placed at the forefront | speculation |
| solid-state batteries aretechnology that is extended from the main businessand is not an independent business | on the official website, solid-state batteries are mentioned as one of the ‘core technologies’ out of four, and do not appear in the ‘product application’ section | speculation |
| Battery-selling companyAnd, we do not intend to make cars ourselves | Other companies such as BAIC Jigao, First Automotive Works, Shaanxi Heavy Truck are also included as partners, and they are also working with EHang | fact |
| Increasing customers other than GuangqiCondition for independencehas become | Guangqi is selling a portion of its stake in 2024 and explaining itself as ‘private holding company’ | speculation |
| solid-state batteries areIt is not yet at the stage where it can be promised externally. | The only fact written is “A-sama cell underline,” and neither the timing, numerical targets, nor the customer are mentioned. | speculation |
The structure of the official website well represents this company’s position. fact ‘Core Technology’ isXFC Ultra-fast Charging · Phoenix Battery · Composite Solid Electrolyte · High Safety for All Weather Conditionsof the four. On the other hand, ‘Product Application’ iscars, commercial vehicles, low-altitude economy, ultra-fast charging terminalsof the four All-solid-state batteries do not appear here at all。
Technically it is mentioned, but as a product it has not yet been sold. Cell for Mr. AThis expression also means the same thing. In the automotive industry, Mr. A (A sample) isthe first prototype to see if the design thinking works. It is not something made using production materials or processes. Typically, after Mr. B and Mr. C, it goes into mass production. The fact that Mr. A came up with this means it does not necessarily mean ‘mass production is near’.It should be read as such. Unconfirmed / Future。
9. Mapping of solid-state battery collaborations
10. Technology Approach Used
| Item | The content that has been made public. |
|---|---|
| All-Solid-State Battery Roadmap | Unique CFS Composite Solid ElectrolyteTechnology Roadmap. ‘The three major challenges of ultra-fast charging, high safety, and high energy density are being addressed.’ |
| The endpoint of full-solid-state batteries | Mr. A’s cell is underlined(The prototype was completed) |
| Numeric values of all-solid-state batteries | Energy density, output, lifespan, and other numerical targets areall not yet announced |
| XFC battery for main business | Fastest charging from 0 to 80% in just 5.5 minutes. WRCA ‘World Record Certification’ for the fastest electric vehicle charging technology |
| Phoenix Battery (2023) | 0 to 80% charge in 6 minutes, 1000km range per full charge, platform compatible with voltages from 300 to 1000V |
| All-weather compatibility | Achieved stable fast charging under all climate conditions through innovation in material systems and thermal management, verified by a CNAS-accredited laboratory |
| Product series | Ultra-fast (charging 5~10 minutes) and super-fast (charging 10~15 minutes) in two series. However, this is the main product of the liquid system. |
The official website is‘CFS composite solid electrolyte’}the term is used but… The abbreviation for CFS and what materials it is composed of are not mentioned. Unconfirmed / Future. This article does not estimate. What is clear is‘composite’the only thing that is included in this phrase.
Making solid electrolytes ‘composite’ is a common direction in this field. Sulfide systems are fast-moving ions but weak against water, oxide systems are stable but hard, polymer systems are soft but have difficulty moving ions at room temperature. It cannot be satisfied with just one of these, so more than two should be mixed to cancel out the weaknessesThis is the design Unconfirmed / Future。
However, in the case of GigaBay KeikenshaThere is a possibility that their aim differs slightly from other companiesThis is because according to the company’s explanation, ‘ultra-fast charging’ comes first. In fast charging, It must pass a large amount of lithium ions through the electrolyte in a short time.Ion conductivity works directly. Generally, all-solid-state batteries are known for ‘safety and range’, but this company is‘an all-solid-state battery that can charge quickly’as it can be read Unconfirmed / Future. This is the interpretation of this article and does not reflect what the company has explicitly stated.
11. The risks this company faces
| Risks | Content | Classification |
|---|---|---|
| There is no means to verify from the outside | Non-listed companies do not disclose financial information, so there is no way to confirm the sales, profits, and funding situation. | fact |
| There is insufficient information about full-solid-state batteries. | The only points published are ‘CFS route’ and ‘Mr. A’s underlined cell’. There is also no time, value, or customer. | fact |
| Mr. A does not mean near mass production | Mr. A’s cell is the first prototype to see the design completion. It usually progresses through Mr. B and Mr. C before reaching mass production. | speculation |
| Parent company’s share reduction | Guangqi Group is selling off a portion of its shares in 2024. The extent of the capital relationship remaining has not been disclosed | fact |
| Conflict between core business and full-solid-state battery resources | In light of the significant investment required for the construction of charging networks, including ultra-fast charging batteries for core business, it is unclear how much can be allocated to full-solid-state batteries | speculation |
| Common risks among startups | Having early access to production equipment and customers is a strength, but as a non-listed company, funding sources are limited | speculation |
| ambiguous domain | The greaterbaytech.com domain is currently being sold on a domain sales page, making it easy for readers to stumble upon. | fact |
