All lithium battery blasts are caused by battery heating caused by short circuit. The reasons for short circuit are overcharge, overdischarge, straight connection of positive and negative electrodes, and electrolyte leakage. Therefore, in the lithium battery planning, we can start from the following points: 1. Prevent overcharging of lithium batteries above 4.2V; 2. Prevent overdischarge of lithium batteries below 2.75V; 3. Install explosion-proof valves on the metal casing; 4. , Prevent short circuit during the process. The best way is of course to have a lithium battery protection circuit board plan. Although this will increase the manufacturing cost of lithium batteries, the safe use of lithium batteries is necessary, and all the products of formal lithium battery processing manufacturers are unavoidable of this plan.
