Li(NiCoMn)O2 and Semi-Solid-State Lithium Batteries Advantages

Standard Lithium Polymer (Suitable for mass production, cost-effective, universal applications)

Low cost, high rate available: Mature technology, yield rate >95%, low unit price, suitable for high-volume digital, IoT, and wearable devices.
Stable fast charging/discharging performance: Low impedance of liquid electrolyte, fast charging and discharging speed, stable high-rate output, compatible with Bluetooth, speakers, and gamepads.
Mature technology, strong compatibility: Standardized size, direct replacement, no production line modification required, ready to use.
Balanced cycle life and reliability: 500-600 cycles are sufficient, low self-discharge, stable for daily use, minimal after-sales service.
Complete supply chain: Complete materials, equipment, and certifications, including UN38.3, IEC62133, and RoHS, ensuring worry-free cross-border operations.

Semi-Solid-State Batteries (Next-Generation Upgrade Direction)

Higher Energy Density: 20%-40% higher than conventional ternary lithium batteries, resulting in longer battery life in the same volume and a thinner, lighter battery for the same battery life.
Significantly Improved Safety: Less electrolyte, less flammable; does not catch fire or explode upon puncture/compression, making it more suitable for wearables, children, and medical applications.
Stronger Low-Temperature Performance: Maintains 70%+ capacity at -20℃ to -30℃, more stable in outdoor, northern, and cold chain equipment applications.
Thinner and More Flexible: Can be made into thinner soft packs, supports slight bending, suitable for curved wearables and compact structures.
Longer Cycle Life: Up to 800-1000 cycles, longer lifespan for high-end devices.
