Contact UsLithium-Ion Battery Fires: Causes, Risks & Preventive Measures
Nearly all lithium battery fires are caused by short circuits. A short circuit happens when the electrical current flows through an unintended shorter path with minimal resistance. It leads to an electrical overload. Currents that are 20 to 50 times stronger than the battery''s design limitations overwhelm the cell.
