As an 18650 Battery Factory, share with you. Lithium batteries have the
largest number of applications, and their safety risks can be great.
Needle punch, short circuit failure, extrusion molding.
When the lithium battery has a short circuit failure, acupuncture or extrusion molding, it will cause the internal diaphragm to crack, causing the temperature to rise suddenly, and finally an explosion accident, especially the lithium battery with a weaker safety factor, this time will be even longer. Short, it will explode in about 5 seconds.

Thermal shock refers to the situation where the working temperature suddenly rises. If the temperature rises, the negative surface SEI film of the lithium ion battery will dissolve, which will cause a chemical reaction. If the heat dissipation is not good, the internal temperature of the rechargeable battery will rise rapidly. High, and then an explosion occurs.
Over battery charging flow.
Assuming that the lithium battery is overcharged, unnecessary electromagnetic energy will be converted into energy, which will cause the temperature of the rechargeable battery to rise and be destroyed. Under normal circumstances, this type of problem will appear on some charging heads or electronic devices that are not maintained by the charging head.
Are lithium-ion batteries really environmentally friendly?
Lithium-ion battery: low-carbon and environmentally friendly, free of lead, mercury, cadmium and other harmful heavy metal elements and chemical substances, regardless of manufacturing, application or waste. Others, such as batteries and solid-state batteries, generally contain heavy metal elements such as mercury, lead, and cadmium; these heavy metal elements have large toxic and side effects and cause environmental pollution to the soil layer and water quality.
The use of lithium batteries in the industrial production of pure electric vehicles has become more and more common, especially the emergence of rechargeable batteries as raw materials for lithium iron phosphate batteries, which has promoted the development trend and application of lithium battery industrial production. In terms of the development trend of new energy vehicles, the development trend of lithium batteries is more environmentally friendly, and the development trend of car fuel is also closely related to the development trend of electric energy. With the advent of the crude oil period, the use of car gasoline and diesel engines as driving fuels in cars has not only caused environmental pollution in large cities, but also caused fuel prices to increase due to the shortage of crude oil supplies. Gas cars and bio-engines The emergence of pellet fuel cars as an alternative fuel.
Therefore, the acquisition and reuse of lithium batteries is undoubtedly the main problem of environmental pollution. Whether it is from the collection of raw materials or related to traditional materials, the development trend of lithium batteries and the advantages of ecological protection have just begun to appear gradually. Lithium batteries in driving energy storage systems will become popular.
