As automotive comfort and safety technologies evolve, heated steering wheels are now standard in many mid-to-high-end vehicles. To achieve quick heating, compact integration, and reliable performance under varying conditions, the power source becomes crucial. Semi-solid lithium-ion batteries provide the ideal balance of safety, stability, and temperature adaptability for such automotive applications.

Why Semi-Solid Lithium-Ion Batteries?

Unlike conventional lithium-ion batteries that use liquid electrolytes, semi-solid designs integrate a gel-like electrolyte, enhancing thermal stability and safety. These batteries are particularly suited for vehicle interiors exposed to temperature fluctuations and vibration.

• Wide temperature range: operates reliably from -30°C to +60°C.
• High safety: puncture-resistant, non-flammable, and no thermal runaway risk.
• Stable power output: ensures smooth heating without voltage drop.
• Compact size: adaptable to the limited space inside steering wheel assemblies.
