Raimu Co., Ltd. (Headquarters: Suzuka, Mie Prefecture; Representative Director: Osamu Takayama) has begun pre-sales on the Makuake crowdfunding service for 'enerpad,' a magnetic attachment mobile battery that adopts the next-generation 'semi-solid-state' battery technology to prioritize safety, starting May 19, 2026. As reports of overheating and fire accidents involving mobile batteries increase in recent years, the company proposes a product selection criteria focused on 'everyday safety' rather than just specifications.
[Development Background: Prioritizing 'Visualizing' Quality]
For approximately 30 years, Raimu has operated in the outdoor equipment and electronics sectors. The company believes that moving forward, the criteria for choosing a mobile battery should not just be price or specs, but 'the environment and management systems under which it is manufactured.'
In 2025, Raimu partnered with Taiwan-based Samlife Technology, a company with over 30 years of experience in the battery field, which manages design, quality control, and production internally in Taiwan. After inspecting the manufacturing site and quality control systems, Raimu decided to launch the product in Japan, deeply impressed by the transparency of the manufacturing process and a quality philosophy based on long-term usage.
[What is a 'Semi-Solid-State Battery'? Mechanisms for Enhanced Safety]
The 'semi-solid-state battery' adopted by this product is a next-generation structure different from traditional liquid-electrolyte designs.
- Stability via Gel-State Electrolyte: The internal structure is gel-like (semi-solid), realizing high stability.
- Thermal Runaway Suppression: Designed to minimize the use of flammable materials, making thermal runaway less likely.
- Rigorous Testing: The product has passed safety evaluation tests including nail penetration and crushing tests.
[Product Features]
- Dual Certification: In addition to Japan's 'PSE' compliance, it has obtained Taiwan's strict 'BSMI certification.' The high-quality standards can be verified through public databases.
- Smart Magnetic Charging: Strong magnets allow it to attach securely to the back of an iPhone, enabling smooth, cable-free charging.
- Two Lifestyle Models: Available in a 5000mAh model (approx. 9.5mm thin, 120g weight) and a 10000mAh model (approx. 2 full charges for an iPhone, supports up to 22.5W high-output PD).
