For a practical electric vehicle to be widely accepted in the market, development of next generation batteries with high energy density is critical. So far, Toyota is promoting battery R&D from both the engineering and scientific point of view, and we believe All-Solid State battery using an inorganic solid electrolyte has great potential as a candidate for beyond Li-Ion battery technology.  There are several benefits such as no potential for leakage, a wide electrochemical window, and high thermal stability and these properties enable the design of a series, multi-layer cell, which would result in a high voltage and robust energy device even in harsh environments. In my presentation, I will introduce the current challenges and update some results of Toyota’s All-Solid State battery program.
