Maxell, Ltd. (President and Representative Director: Keiji Nakamura / hereinafter “Maxell”) has succeeded in increasing the energy density of a ceramic packaged all-solid-state battery using a sulfide based solid electrolyte, resulting in a newly developed and commercialized ceramic packaged all-solid-state battery that has approximately twice the energy density of its predecessor*1.
This high-capacity ceramic packaged all-solid-state battery achieved twice the energy density by adopting new technologies regarding structures and processes, while maintaining various properties such as the capacity, output characteristics and heat resistance of the ceramic packaged all-solid-state battery announced in March 2021.
Responding to the requests from FA and infrastructure device manufacturers, Maxell will begin sample shipment of high-capacity ceramic packaged all-solid-state battery achieving half the volume from August 2022.
With this high-capacity ceramic packaged all-solid-state battery, reliability in a 250ºC environment*3 can be maintained – something that was difficult with conventional lithium-ion batteries – and surface mounting is enabled by reflow soldering. Because of their ability to support smaller size and larger capacity*1, sales of these products will also be expanded to the markets such as those of medical devices (where sterilization is essential), FA equipment and in-vehicle equipment, as well as those markets where surface mounting is required.
Maxell is planning to install manufacturing equipment for mass production of the high-capacity ceramic packaged all-solid-state batteries at the Kyoto factory in the spring 2023.
Main features of high-capacity ceramic packaged all-solid-state battery
Announced and released on March 30, 2021 “1st in the World*1 to Develop a Mountable Sulfide Based All-solid-state Battery” https://ssl4.eir-parts.net/doc/6810/ir_material4/156724/00.pdf
*2 operating temperature up to 105ºC for 10 years of use: Estimated from the results of Maxell’s life prediction by various evaluation and analysis
*3 reliability in a 250°C environment: The reflow at the maximum temperature of 250ºC does not show any deterioration in the basic characteristics such as capacity and load characteristics.
