Semi-Solid Lithium-Ion Battery Solutions for Heated Clothing

Compact, safe, and long-lasting battery packs for jackets, vests, gloves and workwear in cold environments.

Heated clothing is a fast-growing wearable segment serving outdoor enthusiasts, winter sports, and workers in harsh climates. These garments require compact, lightweight batteries that deliver stable heat without compromising comfort and safety. With 26+ years of lithium battery manufacturing, PKNERGY provides tailored semi-solid Li-ion solutions optimized for heated apparel.

Application Background

Compact & lightweight: unobtrusive packs that integrate into liners or cuffs.
Stable output: consistent current for steady warmth across multiple heat levels.
Durable & safe: vibration/shock resistance, cold-temperature reliability, multi-level protections.
Long cycle life: supports frequent winter use across seasons.

Traditional cells can be bulky or rigid. Semi-solid Li-ion increases safety and energy density, enabling thinner, more comfortable wearables.

FAQ

How long can a jacket run on 7.4 V 5000 mAh?

Commonly ~5–7 h at medium heat depending on element wattage and ambient temperature. We size packs by your runtime targets.

Is semi-solid safer than traditional Li-ion?

The semi-solid electrolyte design improves thermal robustness and reduces leakage risk; combined with BMS it enhances user safety.

Can you customize connectors and cable lengths?

Yes—garment-friendly housings, flexible leads, and quick-swap interfaces are supported.

What certifications do you support?

UN38.3 for transport, IEC62133/CE/UL as needed. We provide test plans and documentation.
