Are lithium-ion batteries safe?

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, it will cause the internal diaphragm to crack, causing the temperature to rise suddenly, and finally an explosion accident, especially for the lithium battery with a weaker safety factor, this time will be even longer. Short, it will explode in about 5 seconds.

· Thermal shock.

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 charge 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 in 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.

At this stage, the acquisition of lithium-ion batteries has just developed, and the relative utilization rate is only 2%. It is indeed difficult to achieve environmental protection levels. It is widely believed that lithium iron phosphate batteries are more suitable for professional use, and ternary lithium batteries are suitable for immediate acquisition. However, whether it is professional application or recycling system reuse, there are some problems in the early stage of power lithium battery development and design, such as the immature operation model, the lack of reasonable battery recycling and acquisition methods, the unmatched disassembly of rechargeable batteries, and the remaining The service life is unpredictable.

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 environment protection have just begun to appear gradually. Lithium batteries in driving energy storage systems will become popular.
