TDK: ‘1,000Wh/L solid-state battery’

“Utilising proprietary material technology, TDK has managed to develop a material for the new solid-state battery with a significantly higher energy density than TDK’s conventional mass-produced CeraCharge solid-state batteries, due to the use of oxide-based solid electrolyte and lithium alloy anodes,” according to the company, which added: “The use of oxide-based solid electrolyte makes batteries extremely safe.”

It is aiming to replace coil cells in wearables including wireless earphones, hearing aids and smartwatches “in compliance with EU battery regulations, which require them to be replaced by rechargeable batteries”, said TDK, which “will strive to develop the battery cells toward mass production. Moreover, TDK aims to enhance the capacity of the batteries through multi-layer lamination technology and expand its operating temperature range”.
