What is an all-solid-state battery?

An all-solid-state battery is a battery in which the organic electrolyte (flammable), which is a cause of safety issues in lithium-ion batteries, is replaced with a solid electrolyte, and high safety (flame retardant and leak-free) can be achieved.

FDK's original technology

We are developing an oxide-based all-solid-state SMD battery utilizing the newly developed cathode material Li₂CoP₂O₇ (LCPO), which offers both high voltage and high capacity. To meet diverse customer needs, we have developed two new models: the SCC4532K, a high-energy-density model, and the SCD4532K, which supports constant-voltage charging.

For more information on the newly developed SCC4532K and SCD4532K, please refer to SoliCell® All-Solid-State Battery in the Product Information section.

FDK's material development

Highly efficient material development is realized using material simulation technology based on computational physics.

For details refer to our high-precision material research technology.

By utilizing this technology, and grasping in detail the electronic state of the material involved in charge and discharge, we have developed a new positive electrode material Li₂CoP₂O₇ to achieve both high potential and high capacity.

For details on the new positive electrode material Li₂CoP₂O₇ developed, refer to the news release.
