Sample shipment of the world's highest level high voltage/ultra small size all-solid-state battery

FDK

Realized High Voltage (3.0V), High Energy Density by Oxide Based SMD Type

FDK corporation will begin sample shipment of oxide based all-solid-state battery using high electrochemical potential cathode material «lithium cobalt pyrophosphate (Li2CoP2O7)» which was jointly developed with Fujitsu Laboratories Ltd. February 2017.

Sample shipment of the world's highest level high voltage/ultra small size all-solid-state battery

While applications using various batteries such as IoT devices and wearable devices expand and progress, the specifications required for batteries are becoming increasingly diverse, and, in particular, there is increasing interest in high energy density and safety performance. Respond to these needs all-solid-state batteries are attracting attention as next generation battery, FDK has been continued to develop all-solid-state battery using high electrochemical potential cathode material «lithium cobalt pyrophosphate (Li2CoP2O7)» with features such as high energy density, superior safety performance, and long life.

This battery is SMD (Surface Mount Device) type, so they can be mounted as one of the electronic parts, contributing to miniaturization of equipment and began shipping samples at the end of 2018.
