Battery Technology Comparison

Standard Lithium Batteries

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 with low impedance liquid electrolyte
Standardized size for direct replacement, no production line modification required
Balanced cycle life (500-600 cycles) with low self-discharge and minimal after-sales service
Complete supply chain with UN38.3, IEC62133, and RoHS certifications

Semi-Solid-State Batteries (Next-Generation)

20-40% higher energy density than conventional ternary lithium batteries
Significantly improved safety with less flammable electrolyte
Stronger low-temperature performance (70%+ capacity at -20℃ to -30℃)
Thinner and more flexible design for curved wearables and compact structures
Longer cycle life (800-1000 cycles) for high-end devices

Key Product Advantages

High Energy Density: Ternary lithium polymer batteries store more energy in the same volume than traditional nickel-metal hydride, nickel-cadmium, or some lithium-ion batteries, making them suitable for small devices with limited space.
Compact and Flexible: Utilizing a soft-pack aluminum-plastic film encapsulation, they are compatible with ultra-thin devices such as beauty devices, reading pens, and smart bracelets.
Stable Discharge Performance: With a nominal voltage of 3.7V and an operating voltage range of approximately 3.6~4.2V, the voltage plateau is stable during discharge, preventing device malfunctions or shutdowns due to sudden voltage drops.
Built-in Protection Mechanism: Equipped with overcharge, over-discharge, overcurrent, and short-circuit protection, enhancing safety.
Long Cycle Life: Under normal use, it can achieve 300-600 charge-discharge cycles with a capacity retention rate of over 80%.
No Memory Effect: Can be charged at any time without complete discharge, making it more convenient to use.
Environmentally Friendly and Safe: Free from toxic substances such as lead and mercury; the polymer encapsulation will only swell rather than explode under abnormal conditions.
