RE:RE:Toyota ready to unveil solid-state battery EV in 2021 ... htRead this Toyota will have silicon in solid state battery!
"Our solid-state batteries are based on lithium ion technology, but with solid-state safety, plus twice the energy density. Also, users can charge them in six-times faster than liquid Li-ion—15 minutes to recharge instead of 1-1/2 hours," Graeme Purdy, Ilika CEO, told EE Times.
"Regarding our relationship with Toyota, we jointly own the patents for the bulk batteries suitable for electric vehicles. But Ilika wholly owns the patents for small batteries," Purdy said. "Out patents covert three aspects: the combination of materials compared to conventional lithium ion, secondly the process (evaporation) is patented—instead of powder to ink-based printing on foil we heat to evaporate at 400°C—and thirdly we have patented the architecture and our way to combining the different ingredients."

The key, however, to solid-state batteries, according to Purdy, is the use of a silicon anode, which eliminates the need for a liquid electrolyte, is easier to encapsulate against the environment and even if partially exposed, has less of a reaction to air and moisture than liquid electrolyte Li-Ion batteries.
