What Happens When You Overcharge A Lithium Ion Battery. If a battery gets too hot it could explode or begin to burn. The thermal runaway reaction during overcharge was caused by the violent reaction between the overcharged anode deposited lithium and the electrolyte solvent at high temperature that was the result of the rapid exothermic reaction of the delithiated cathode.
In a lithium-ion battery overcharging can create unstable conditions inside the battery increase pressure and cause thermal runaway. Lithium-ion batteries will face the risk of excessive self-discharge during long-term storage especially at lower open-circuit voltages. And if they ever show signs of defect stop using them right away.
Overcharging causes damage to the battery and creates a safety hazard including fire danger.
In a lithium-ion battery overcharging can create unstable conditions inside the battery increase pressure and cause thermal runaway. At best this will lead to reduced capacity and shortened life cycle and at worst this could cause thermal runaway. With the pressure inside if heat is a factor the battery may explode. Excessive charging can bring on thermal run away in a lithium battery.
