Tokyo Tech introduces fabrication process for low-resistance solid-state batteries

Solid-state batteries are theoretically safer, more stable, and have higher energy densities than conventional Li-ion batteries with liquid electrolytes. Unfortunately, they also tend to have relatively high resistance at the interfaces between their electrodes and solid electrolytes, which can limit the rate of charging and discharging. In order to solve this, researchers from the Tokyo… Read more »

New electrolyte for solid-state batteries combines polymer and glass

Scientists at the DOE’s Lawrence Berkeley National Laboratory have developed a novel electrolyte that addresses many of the problems of solid electrolytes by combining the two primary types – polymer and glass. There are two kinds of solid electrolytes – polymer and glass or ceramic – and each has its own set of challenges. Polymer… Read more »

Hitachi researchers demonstrate thermally durable solid-state Li-ion battery

A research team sponsored by Hitachi and Tohoku University’s Advanced Institute for Material Research (AIMR) has demonstrated technology that reduces the internal resistance of all-solid-state Li-ion batteries through the use of LiBH4-based complex hydrides as solid electrolytes. A conventional Li-ion battery uses a volatile organic electrolyte solution with a maximum operating temperature around 60˚ C…. Read more »

PATHION’s superionic solid-state electrolytes point to more powerful and safer batteries
