What are the safety hazards of using lithium batteries?

Are lithium batteries safe? The most commonly used lithium battery has many potential safety hazards. ▲Acupuncture, short circuit, squeeze When a short circuit, acupuncture or squeeze occurs in a lithium battery, it will cause the internal diaphragm to rupture and cause a sudden explosion in temperature, and eventually an explosion will occur, especially for lithium batteries with poor safety performance. This time will be shorter, and it will explode in about 5 seconds. ▲ Thermal shock The so-called thermal shock is the phenomenon of a sudden increase in the ambient temperature. If the temperature is high, it will cause the SEI film on the negative electrode surface of the lithium battery to decompose, which will cause an exothermic reaction. If the battery heat dissipation is not good, the internal temperature will be It rises rapidly, causing a deflagration phenomenon. ▲Overcharge If the lithium battery is overcharged, the excess electric energy will be converted into heat energy, which will cause damage to the temperature of the battery body. Often this problem will appear in some chargers or electronic products without overcharge protection. Will the power lithium battery pack explode if heated? Lithium batteries are almost everywhere in life, and electronic products such as mobile phones, tablets, cameras, and notebook computers are powered by lithium batteries. However, power lithium battery packs sometimes overheat or explode due to certain unexpected conditions. With the increasing capacity of batteries today, user safety issues have also attracted special attention.
