Frequently Asked Questions
Electrochemical aging causes loss of active lithium and electrode degradation, increasing internal resistance. This reduces capacity and efficiency over time, making cycle life testing essential for predicting long-term battery performance.
Internal resistance affects heat generation, efficiency, and power delivery. Higher resistance leads to energy loss and temperature rise, directly impacting battery performance and safety.
Lithium plating occurs when charging rates exceed intercalation capability, especially at low temperatures. Metallic lithium deposits on the anode surface, causing capacity loss, increased resistance, and potential safety risks like internal short circuits.
Higher C-rates increase current flow, leading to heat generation, mechanical stress, and faster degradation of electrode materials. Lower C-rates improve stability but reduce charging and discharging speed.
Temperature variations within a battery pack cause uneven aging and performance differences between cells. This imbalance reduces overall efficiency and lifespan, requiring effective thermal management systems.
