It is impressive that hexagonal buildings are lined up in the center.This is the Utsunomiya Exam, a battery safety certification center of Espec Co., Ltd., which is about a 20 -minute drive from Utsunomiya.
In anticipation of the device revolution that will be coming in the near future, SoftBank is working on the development of next -generation batteries, and in order to further accelerate the research, "SoftBank Next Generation Battery LAB".It was announced in March 2021 that it will be established.Five months after the establishment, I have participated in the lab tour.
A secondary battery called a battery that can be used repeatedly with charging and discharge.At present, lithium -ion batteries are the mainstream, but the next -generation batteries that greatly improve high energy density (lighter weight), life, safety, and cost are essential for supporting evolved devices.
Softbank aims to develop batteries that become the same energy (WH, wat hour) with half weight, that is, batteries with high -quality energy density.In order to create high -energy batteries, the next generation 400-500Wh/kg (up to 550WH/kg) class battery, and the next -generation 600-1000Wh/kg (up to 1000WH/kg) class with high energy density.Aiming for realization, it was established "SoftBank Next Generation Battery LAB."is.
“Next -generation batteries” is key technologies for innovation evolution.Why SoftBank develops batteries
