I recently read about Toyota planning to produce solid-state EVs in Japan by 2026, with plans to have them on the road by 2027. They got the green light from the Japanese government last September to bring these batteries to market.

This made me curious. I knew they have a huge portfolio of 1700 patents in solid-state battery tech, and I wanted to dig more into what Toyota is doing to improve the performance of SSBs.

So I asked Slate Pro about it- 

You can find the entire discussion here. 

Two of their patents tackling critical SSB challenges caught my eye, and I thought I’d share them with you- 

1. Increasing Charging Speed
   This patent (US20240021797A1) introduces a composite particle with a fluorine-based coating film for all-solid-state batteries. The coating minimizes resistance, especially under high voltage, enabling faster charging. The innovative use of fluorine, phosphorus, and glass network formers ensures durability and reduces energy loss, making this technology crucial for ultra-fast EV charging solutions.
   
2. Enhancing Battery LifeAnother patent (US20240038972A1) discusses an electrode material with alternating fluoride and sulfide electrolyte layers to reduce resistance degradation over time. This technology lowers the need for frequent replacements, making EVs more cost-effective and sustainable for users.
