Nickel Metal Hydride No. 5 battery

　　Are Nickel Metal Hydride No. 5 battery safe?

　　Lithium batteries have the largest number of applications and can pose significant safety risks.

　　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 a sudden increase in temperature, and finally an explosion accident. Especially for lithium batteries with weak safety factors, this period of time will be more serious. Short, usually about 5 seconds before an explosion occurs.

　　·Thermal shock resistance.

　　Thermal shock refers to a sudden increase in operating temperature. If the temperature rises, it will cause the SEI film on the negative surface of the lithium-ion battery to dissolve, thereby causing a chemical reaction. If the heat dissipation is not good, the internal temperature of the rechargeable battery will rise rapidly. High, resulting in an explosion.

　　over battery charge flow.

　　If the lithium battery is overcharged, unnecessary electromagnetic energy will be converted into energy, causing the temperature of the rechargeable battery to rise and cause damage. Generally, this kind of problem will occur on some charging heads or electronic devices that do not have charging head protection.

　　Are Nickel Metal Hydride No. 5 battery really environmentally friendly?

　　Lithium-ion battery: low-carbon and environmentally friendly, does not contain lead, mercury, cadmium and other harmful heavy metals and chemicals, regardless of production, use 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 serious side effects and cause environmental pollution to soil and water quality.

　　The use of lithium batteries in the industrial production of pure electric vehicles is becoming more and more common, especially the emergence of lithium iron phosphate battery raw material rechargeable batteries, which has promoted the development trend and application of lithium battery industrial production. As far as the development trend of new energy vehicles is concerned, 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 era, cars use gasoline and diesel engines as driving fuel, which not only causes environmental pollution in cities, but also causes an increase in fuel prices due to the shortage of crude oil supply. Gas cars and biomass The emergence of pellet fuel cars as an alternative fuel.

　　At this stage, the field of lithium-ion battery acquisition in China has just developed, and the relative utilization rate is only 2%. It is indeed difficult to achieve environmental protection levels. It is generally believed in China that lithium iron phosphate batteries are more suitable for professional use, while ternary lithium batteries are suitable for immediate purchase. However, whether it is professional use or recycling, there are some problems in the early stage of power lithium battery development and design, such as immature operating models, lack of reasonable battery recycling and acquisition methods, mismatching of disassembled batteries, and remaining batteries. The service life is unpredictable, etc.

　　Therefore, the acquisition and reuse of lithium batteries is undoubtedly a major problem of environmental pollution. Whether it is related to raw material collection or traditional fuel, the development trend and environmental protection advantages of lithium batteries are beginning to emerge. Lithium batteries will become popular in power energy storage systems.
