Development Background
The widespread adoption of mobile batteries has unfortunately been accompanied by reports of abnormal heat generation and fire incidents. Concurrently, there has been a rapid increase in demand for portable power sources for wearable gear, such as air-conditioned clothing for summer outdoor activities and heated vests for winter warmth.
However, conventional batteries are often susceptible to rapid temperature changes, leading to issues like reduced output in summer heat and significant battery drain in extreme cold. Recognizing the critical need for “safety and reliability” that remains unaffected by environmental conditions, especially for devices used close to the body and in harsh environments, Magnetic Laboratories Co., Ltd. developed this next-generation mobile battery. It incorporates the latest semi-solid battery technology and a self-developed IC circuit to achieve robust temperature resistance.
Product Features
1. Significantly Reduced Fire Risk with Next-Generation Semi-Solid Battery
The HIDISC semi-solid mobile battery utilizes a gel-like electrolyte, a departure from conventional liquid lithium-ion batteries. This design successfully minimizes the risk of liquid leakage and fire, even in the event of impact or overcharging. This provides an enhanced level of safety for daily use and in demanding outdoor conditions.
2. Exceptional Temperature Resistance from -20℃ to 55℃

This product boasts remarkable stability, performing reliably across a broad spectrum of temperatures. It operates safely and normally from scorching summer heat (55℃) under direct sunlight to the extreme cold (-20℃) encountered in winter sports or frigid regions. This ensures consistent performance regardless of weather or season.
3. Multi-Smart IC for Air-Conditioned Clothing, Heated Vests, and Smartphones

Equipped with a “Multi-Smart IC,” the battery automatically detects connected devices and delivers optimal, stable power. It can safely and smoothly power high-output, fluctuating load devices like air-conditioned clothing and heated vests, as well as delicate smartphones. This offers year-round convenience and versatility.
4. Lightweight and Compact Design Enabled by High Energy Density

Leveraging the high energy density characteristic of semi-solid batteries, the product achieves a lightweight and compact design. The 5000mAh model weighs approximately 100g, making it easy to carry in a bag or pocket without discomfort. Even when used in clothing pockets for air-conditioned apparel or heated vests, its minimal weight ensures a comfortable experience.
5. Economical and Eco-Friendly with Approximately 2,000 Charge Cycles

Surpassing the typical lifespan of conventional lithium-ion mobile batteries (approximately 500 cycles), this product offers an impressive 2,000 charge-discharge cycles. Its resistance to degradation over long-term use reduces the frequency of replacements, making it an economical and environmentally friendly choice.
