Cost
Among the types of lithium battery, LFP batteries are often seen as a cost-effective option for applications requiring long-term reliability. Their extended cycle life and lower maintenance needs reduce operational expenses over time. On the other hand, LCO, NMC and NCA batteries, with their higher energy densities, may come at a slightly higher upfront cost but offer excellent performance for weight-sensitive applications like electric vehicles and portable devices.
Performance in Extreme Temperatures
Extreme temperatures can significantly impact the performance and safety of lithium batteries. At low temperatures, the electrolyte inside the battery becomes less mobile, which slows down the chemical reactions. This can lead to lithium plating, a condition where lithium ions deposit unevenly on the anode. Over time, this causes permanent capacity loss and increases safety risks due to dendrite formation. High temperatures, on the other hand, accelerate chemical reactions within the battery. This not only shortens its lifespan but also raises the risk of thermal runaway, a dangerous condition where the battery overheats uncontrollably.
Large Power’s low-temperature batteries are specifically designed to perform effectively in temperatures below 0°C, unlike standard lithium-ion batteries. They retain approximately 50% of their charge and discharge capacity even at temperatures as low as -50°C. This technology helps prevent issues like reduced capacity, slower charging, and potential safety hazards that typically occur in standard batteries at low temperatures.
