TDK has developed a solid oxide electrolyte material that boosts the energy density of its solid state battery cells by 100x.

The oxide used for the latest CeraCharge solid state battery provides an energy density of 1,000 Wh/L, a key target for battery makers and approximately 100 times greater than the energy density of the current TDK solid state battery.

The solid state battery is aimed at wearable devices such as wireless earphones, hearing aids and even smartwatches, with the goal of replacing existing coin cell batteries.

It uses lithium alloy anodes with the oxide-based solid electrolyte to ensure that the cell is safe to use, which can be a challenge for lithium metal batteries, and is intended devices that come in direct contact with the human body as well as powering environmental sensors such as the recent reference design with Nanopower Semiconductor.

The battery can be applied for replacing coin cell primary batteries in compliance with EU battery regulations, which require them to be replaced by rechargeable batteries, which is expected to contribute to the reduction of environmental impact.

TDK is developing the battery cells and package structure design for mass production with the multi-layer lamination technology that is used for its multi-layer ceramic capacitor (MLCC) devices. It is also extending the operating temperature range by applying the production engineering technology TDK has accumulated in the electronic components business.
