Battery safety refers to the set of design principles, operational practices, and protective technologies that ensure a battery operates reliably and securely, without posing risks of fire, explosion, chemical leakage, or electrical hazards. It is a critical focus in the development, deployment, and regulation of lithium-ion batteries, energy storage systems (ESS), electric vehicles (EVs), and consumer electronics.
Common Battery Safety Risks:
Thermal runaway: An uncontrollable rise in temperature due to internal short circuits, overcharging, or external heating, potentially leading to fire or explosion
Overcharging/over-discharging: Can degrade cell materials and lead to gas generation or internal damage
Mechanical damage: Punctures or crushing can compromise internal structure and cause short circuits
Electrical abuse: Short circuits or high current surges can result in overheating and component failure
Electrolyte leakage: May result in chemical burns, corrosion, or toxic exposure
