KOHAKU JAPAN to Launch Semi-Solid Mobile Battery Featuring Hanshin Tigers Logo, Designed for Everyday Use by Fans, Available from June 2026
KOHAKU JAPAN Inc. (Headquarters: Katsushika-ku, Tokyo) announces the upcoming release of the “Hanshin Tigers Logo Semi-Solid Lithium-ion Mobile Battery (5,000mAh)” through its brand ‘KOHAKU e-life’. This new product, featuring the official logo of the professional baseball team Hanshin Tigers, will be available for purchase starting June 2026 on the KOHAKU JAPAN EC site and Amazon.co.jp.
The mobile battery incorporates a semi-solid battery, designed with enhanced safety in mind. This technology significantly reduces risks such as ignition compared to conventional ternary lithium-ion batteries, allowing for safer use even in high-temperature environments. It also boasts a design suitable for daily use, catering to Hanshin Tigers fans.
Background
The widespread use of smartphones and mobile devices has increased the importance of portable power sources for daily life. Concurrently, there is a growing demand for items used at sports events and during outings to possess both “design appeal” and “support elements.” In response to these needs, the company planned this model as a product that combines safety and practicality with the joy of fandom in everyday life.
Product Features
Hanshin Tigers Logo Design Model
The mobile battery comes in designs featuring the “HANSHIN Tigers” and “Tigers Girls” logos. The robust black body showcases the iconic HANSHIN Tigers logo, embodying the fierce spirit of the team. The elegant white body features the Tigers Girls logo, creating a refreshing image. High-quality printing ensures vibrant colors and resistance to wear even with prolonged use.
Enhanced Safety with Semi-Solid Lithium-ion Battery
The adoption of a semi-solid battery ensures a design with increased safety compared to traditional lithium-ion batteries. Semi-solid batteries reduce the liquid component compared to conventional ternary lithium-ion batteries, preventing electrolyte leakage and successfully mitigating risks such as ignition. The battery is equipped with multiple protection functions against overcharge, over-discharge, short circuit, and temperature fluctuations. It has a proven track record of not igniting or emitting smoke even in nail penetration tests, remaining functional as a mobile battery. Compared to conventional lithium-ion batteries, semi-solid batteries also offer a longer lifespan and are less prone to degradation, ensuring safer and more stable performance over an extended period.
Wireless Charging Capability
The device supports wireless charging, allowing smartphones to be charged simply by placing them on the battery. It offers a maximum output of 15W, enhancing convenience for daily use. Furthermore, wired output supports rapid charging up to 20W, and simultaneous wired and wireless charging is also possible.
Compact and Portable Design
Weighing approximately 132g, the compact size makes it easy to carry, making it ideal for sports events and outings.
