The CEO of the EV start-up Atlis Motors, Mark Hanchett, recently commented on the solid-state batteries technology naming its four major issues while sharing an article that discusses the impact that this technology can have in the Auto industry.

Hanchett named the slower charge rate, the lower high discharge rate capacity and also the lower power density besides the cycle life problems.

“Every asks us “What about solid state batteries”. Read this carefully, it is the best assessment of solid state batteries I’ve read to date that isn’t marketing hype with tremendous misinformation,” Hanchett started to say.

Atlis Motors CEO defends that most of the articles about this technology are not telling the whole story enhancing that it should be released more data regarding the discharge curves and characteristics of the tests made with these batteries.

“Solid state batteries have higher resistance, resulting in slower charge rates, lower high discharge rate capacity, and lower power density. Solid state batteries have cycle life problems. We’ve all seen articles regarding cycle rates, but they’re not telling you the whole story”.

“The discharge curves and characteristics of the test aren’t published, only small snippets of data. They do have increased safety, but when discharge large amounts of energy over a very short period of time, heat is always going to be a factor,” Atlis Motors CEO said.

“When solid state technology catches up, we’ll be ready. Our Cube cell could accept solid state chemistry solutions right away, and we’re actively moving towards this. The next few years are going to be interesting,” he concluded.


In June, the EV startup signed a memorandum of understanding with INDe EV Limited to develop 500 30 KWh battery packs with deliveries expected in December 2023. Atlis began the development of the AMV battery cell at its headquarters in Mesa, Arizona, in June 2021 becoming the first in the industry to charge in less than 15 minutes

The company added that, by building battery cells in-house, Atlis is “developing its own battery supply chain, working to provide ultra-fast charging batteries to companies that are currently struggling to secure their own allotment from top battery suppliers”.

Recently, Atlis announced the signature of an agreement with the defense vehicle developer Advent Atum to buy its fully electric vehicle platform, the ATLIS XP. The company headquartered in Holsworthy (Australia) will use the platform in the development of its autonomous defense and specialist commercial products.

The XP platform is the only full suite EV skateboard solution to convert a traditional internal combustion engine (ICE) vehicle to an EV and Atlis plans to begin its production by the end of 2022.
