Forgetting your cable is a thing of the past. New release of a semi-solid-state battery mobile power bank that combines high safety and portability.

Elecom Co., Ltd. (Headquarters: Chuo-ku, Osaka; President & CEO: Koichi Ishimi) will sequentially release the "Cable-Integrated Semi-Solid-State Mobile Battery," which features a semi-solid-state lithium-ion battery for high safety and long life, and is convenient to carry with its integrated cable, starting in early April 2026.

Elecom launched a mobile battery with a "lithium iron phosphate battery" in 2022, and the world's first(*1) mobile battery with a "sodium-ion battery" in 2025. In March 2026, we released a product using a "semi-solid-state lithium-ion battery" as a long-life mobile battery that further improves safety and is convenient for carrying.

This product is the second installment of our mobile batteries using semi-solid-state lithium-ion batteries. It is a convenient integrated model with a directly attached USB Type-C(TM) cable. There is no need to carry a separate charging cable, making it suitable for use on the go. The cable is made of a nylon mesh material that is resistant to surface scratches and can be carried while plugged into a port, so it does not get in the way inside a bag or pouch.

*1: According to a market survey on "world's first" for mobile batteries (products) using sodium-ion batteries / capacity 9,000mAh / USB Type-C compatible (45W output / 30W input) conducted by Future Trend Research Institute, Inc. as of November 27, 2024.

What is a semi-solid-state battery?
