Application:
In the smart wearables sector, it's suitable for smartwatches with medium-sized screens larger than 1.3 inches (such as sports monitoring watches) and multi-function health bracelets (with continuous blood oxygen and heart rate monitoring functions).
Its 800mAh capacity supports multiple sensors working simultaneously without frequent charging. In the mini consumer electronics sector, it's suitable for small action cameras (such as thumb-sized portable cameras) and wireless microphones (clip-on).
Its lightweight design doesn't affect the device's portability, and its stable discharge ensures continuous output. In the IoT device sector, it serves as a backup power source for smart door locks (driving emergency unlocking in the event of a power outage) and water quality monitoring sensors (for long-term outdoor monitoring).
Its 800mAh capacity provides 3-6 months of standby time. In the medical assistive device sector, it's used in portable blood pressure monitors (for home use) and micro nebulizers (for pediatric use).
Its stable power supply and high safety meet medical device standards. In the small toy sector, it's suitable for remote-controlled helicopters (20-30cm in size) and smart programmable robots (mini models). Its 1C peak discharge meets the toy's instantaneous power needs, with a battery life of up to 15-20 minutes per charge.
The advantages for Li(NiCoMn)O₂, LiFePO4, LiCoO₂, LiMn₂O₄ batteries:
Ternary Lithium Polymer Battery (Nickel-Cobalt-Manganese / Nickel-Cobalt-Aluminum System)
Leading Energy Density: Volumetric energy density reaches 450-550Wh/L, and gravimetric energy density reaches 150-200Wh/kg. This battery offers 20%-30% higher capacity than lithium iron phosphate batteries of the same size, significantly extending device battery life.
Excellent Low-Temperature Performance: Discharge efficiency remains at 50%-70% at -20°C, far exceeding lithium iron phosphate (20%-30%), making it suitable for outdoor devices in northern winter.
Strong Rate Discharge Capability: Supports 1C-3C conventional discharge and instantaneous peak discharge up to 5C, meeting the transient high-power demands of devices.
Lithium Iron Phosphate Polymer Battery (LiFePO4 System)
Extremely safe: The thermal runaway temperature is approximately 200-300°C, far exceeding the 150-200°C of ternary lithium batteries. It is also less susceptible to fire and explosion when punctured, squeezed, or overcharged, making it suitable for safety-critical applications.
Long cycle life: Typical charge and discharge cycles reach 1000-2000 cycles (at 80% depth of charge and discharge), two to four times that of ternary lithium batteries (300-500 cycles). This makes it suitable for devices with long-term, high-frequency use (such as IoT gateways and smart door lock backup power supplies).
Excellent high-temperature stability: Capacity degradation is only 5%-10%/year at 60°C, with no risk of bulging. This makes it suitable for high-temperature applications such as in-vehicle microsensors and industrial monitoring equipment in summer.
Excellent cost and environmental performance: Containing no precious metals such as cobalt and nickel, raw material costs are 15%-25% lower than ternary lithium batteries, and recycling is easy, meeting green production requirements.
Lithium Cobalt Oxide Polymer Batteries (LiCoO3 System)
Stable voltage platform: The standard voltage is 3.7V, with over 90% of the discharge process remaining in the 3.2-3.7V range. Voltage fluctuations are minimal, preventing device freezes and black screens caused by voltage instability.
High volumetric energy density: Small cells can achieve a volumetric energy density of 500-600Wh/L, 10%-15% higher than ternary lithium batteries of the same size. These cells are suitable for extremely miniaturized devices. Excellent consistency: The production process is mature, with cell capacity and internal resistance variations within the same batch ≤3%, making it suitable for multi-cell series/parallel use.
Lithium Manganese Oxide Polymer Batteries (LiMnO3 System)
Clear cost advantages: Containing no cobalt or nickel, raw material costs are 30%-40% lower than ternary lithium batteries. The simple synthesis process makes it suitable for low-cost mass production applications.
Outstanding rate performance: Supports high-rate discharge of 2C-5C, with a transient discharge current of up to 10C, meeting high-frequency, high-power requirements.
Excellent low-temperature performance: Discharge efficiency at -10°C is approximately 60%-80%, superior to lithium iron phosphate batteries. There is no risk of lithium plating at low temperatures, making it suitable for short-term low-temperature use . Strong processability: The cathode material has uniform particles, making it easy to manufacture into thin battery cells (down to 2-3mm thick), making it suitable for ultra-thin devices (such as ultra-thin smart cards and micro-flexible sensors).
