What is the cause of the explosion of lead-acid batteries

1. Poor battery quality: the separator is of poor quality or defective, allowing the active material of the plates to pass through, resulting in virtual or direct contact between the positive and negative plates; 2. Overcharging: Lead-acid batteries will electrolyze the battery when overcharging The moisture in the electrolyte will produce hydrogen and oxygen after being electrolyzed. These are flammable and explosive gases. When the hydrogen content in the battery or in the air accumulates to the explosive limit, it will most likely burn if it encounters an open flame outside. Or explode. 3. Blocked vent holes: Due to the blockage of the vent holes of traditional lead-acid batteries, the battery will burst first, which will cause the battery to vibrate, and sparks will appear when the pole wiring is not strong, which will lead to an explosion. Regardless of whether it is a lithium battery or a lead-acid battery, a safety valve will be set for the abnormal increase of internal pressure during the design. Qualified lithium battery and lead-acid battery can fully ensure the safety of users, and there is no clear safety difference. . Even if there is an abnormal situation such as a short circuit inside the battery, the internal pressure will be released in time, which will not cause a big risk.
