Elecom Launches New Mobile Battery with Semi-Solid State Battery Technology, Ensuring Safety, Longevity, and Easy Replacement Indicators

Elecom Launches New Semi-Solid State Mobile Battery Focusing on Safety and Longevity

Elecom Co., Ltd. (Headquarters: Chuo-ku, Osaka; President and Executive Officer: Koichi Iwao) announced the launch of a new mobile battery, scheduled to roll out in late May 2026. By adopting semi-solid lithium-ion battery technology, the product offers superior safety and an extended lifespan. This 5,000mAh model is designed for portability and daily use.

### Enhanced Safety Through Semi-Solid Technology

Traditional batteries rely on liquid electrolytes for ion movement. The new semi-solid battery gels the electrolyte, which significantly reduces leakage risks and decreases the amount of flammable organic electrolyte that can cause ignition. By suppressing the generation of flammable gases during internal short circuits, the design dramatically improves overall safety compared to conventional lithium-ion batteries.

### Visualizing Battery Health with 'Health Monitor'

The new 'Health Monitor' feature automatically diagnoses battery health based on charge/discharge cycles and displays the status via LED indicators. This allows users to easily judge when the battery needs maintenance or replacement, ensuring a safer user experience. Battery levels can also be checked in 1% increments.

### Four Times the Longevity and Wide Temperature Range

Due to the chemical stability provided by the gelled electrolyte, the battery achieves a cycle life of approximately 2,000 cycles, which is four times longer than traditional counterparts. Furthermore, it supports discharge in a wide temperature range from -15°C to 45°C, making it reliable in extreme environments.

### Reliable Circuit Design and Environmental Consideration

In addition to five protective features—such as overcharge, over-discharge, and overcurrent prevention—it includes 'Thermal Protection' to monitor and control temperature during operation. The product also reflects environmental considerations, utilizing recycled plastic for the casing and paper from sustainable forests for packaging.

The product is available in black and white, sold at an open price.
