Frequently Asked Questions
Repeated cycling causes electrochemical and structural changes such as electrode degradation, electrolyte decomposition, and lithium plating, leading to gradual capacity loss and increased internal resistance, which are key indicators of device aging.
Internal resistance determines energy losses and heat generation; higher resistance reduces efficiency, limits power output, and accelerates thermal degradation, making it a key indicator of battery health and performance.
Temperature affects reaction kinetics and material stability; high temperatures accelerate degradation and thermal runaway risk, while low temperatures reduce capacity and increase internal resistance, impacting performance and safety.
Cycle life defines the number of charge–discharge cycles a device can sustain before reaching a defined capacity loss, providing a key metric for durability, reliability, and economic viability in long-term applications.
Thermal runaway involves uncontrollable heat generation from exothermic reactions, leading to rapid temperature rise, gas release, and potential fire or explosion, posing significant safety risks.
