Battery Chemistry Advantages
Li(NiCoMn)O2 Lithium Batteries
- High energy density and long range
- Low-temperature discharge performance superior to most lithium batteries (except LiCoO2), with minimal capacity loss at low temperatures
- Cobalt content is significantly lower than in LiCoO2 batteries, allowing for controllable raw material costs
- Moderate rate capability, suitable for continuous discharge at low to medium rates
LiCoO2 Lithium Batteries
- High tap density and volumetric energy density, resulting in a smaller footprint for the same capacity
- Stable discharge plateau with minimal voltage fluctuation, ensuring steady output voltage
- Excellent cycle consistency and low self-discharge, resulting in minimal loss during long-term storage at low currents
- Good processability, making them ideal for manufacturing ultra-thin, pouch-type micro-cells
