Features of lithium ion battery

　　High energy. The lithium battery has high storage energy density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries.

　　Good safety performance and long cycle life. The lithium battery has no structural changes in the lithium ion insertion and dehydration on the cathode and anode during the charging and discharge process (in the process of insertion and dehydration, there will be some expansion and contraction) Stable, lithium branches crystal will not be formed during the charging and discharge process, which significantly improves the safety performance of the battery, while the cycle life is also greatly improved. The service life can reach more than 6 years, and the lithium metal phosphate is a 1C (100%DOD) battery with a positive electrode, and there are records of 10,000 times.

　　The rated voltage is high. The single operating voltage of the monomer is 3.7V or 3.2V, which is about 3 series voltage of 3 nickel -cadmium or nickel -metal hydride battery, which is convenient for the battery power group; lithium batteries can use a new type of lithium battery pressure regulator technology to turn the voltage voltage Trow up to 3.0V to the use of small appliances.

　　The self -discharge rate is very low. This is one of the most prominent superiority of lithium batteries. Generally, it can be less than 1%/20 of nickel -metal hydride batteries. The lithium battery adopts a non -hydrolytic fluid system, and the lithium -carbon material is unstable in thermodynamics in the non -hydraulic fluid system.

　　Light weight. The weight under the same volume is about 1/6-1/5 of lead-acid products.

　　Putting low temperature. It can be used in the environment of -20 ° C-60 ° C. After processing, it can be used in -45 ° C environment. Lithium batteries and lead batteries will lose useful energy capacity under cold weather conditions. However, the effect is much more effective for lead batteries.

　　Green. Regardless of production, use, and scrap, it does not contain, nor does it produce toxic and harmful metal elements and substances such as lead, mercury, cadmium, etc. At the same time, because the battery must be well sealed, there are very few gas releases during use, and it does not cause pollution to the environment. The solvent used to dissolve binders during the manufacturing process can also be completely recycled.
