MOTTERU Announces Semi-Solid Mobile Battery It Says Hardly Catches Fire
The semi-solid design directly answers growing user concern over battery fires and abnormal heat, trading capacity for safety and longevity in a consumer product.

MOTTERU announced a new-generation semi-solid mobile battery series that uses a proprietary clay-like electrolyte instead of liquid. The company says this greatly reduces leakage, short-circuit, and fire risks, passing a nail penetration test without catching fire. It operates from -10 to 60 degrees Celsius and lasts more than 2,000 charge/discharge cycles, about four times conventional lithium-ion batteries. The lineup starts at 4,970 yen, on sale in September, with a 2-year warranty.
MOTTERU built the series around a shift in the electrolyte itself, moving from volatile liquid to a clay-like, gel-like state that holds its shape. The company puts the safety claim to a severe test: a sharp nail pierced into the battery produces no fire, a standard that liquid cells routinely fail.
The operating range is wide, from -10 to 60 degrees Celsius, so the battery is meant to survive both freezing outdoor use and a hot car dashboard in summer. The life claim is also large, more than 2,000 charge/discharge cycles, roughly four times the typical 500-cycle end of life for conventional lithium-ion cells.
The 5000mAh model with a strap-type cable weighs about 106g and carries an LCD display whose readout color matches the battery body. All units come with a 2-year product warranty.
