The advantages and application of ternary polymer lithium battery industry

Source: 2020 - 04 - 04 'hits: ternary polymer lithium battery application industry advantage of ternary polymer lithium-ion batteries for its balance capacity and safety coefficient, is a kind of comprehensive performance of the battery. The main functions of the three kinds of metal elements application is as follows: high power density is the ternary polymer lithium battery greater competitive advantage, and the working voltage platform is the basic technology of battery power density index, according to the battery performance and cost, on the basis of working platform, the higher the voltage, electric capacity than is bigger, so the same volume, weight, or even the same battery, high working voltage platform ternary material lithium battery life longer. Single ternary polymer lithium-ion battery discharge voltage platform up to 3. 7 v, lithium iron phosphate battery is 3. 2 v, lithium titanate battery is only 2. 3v。 Therefore, in terms of power density, the ternary polymer lithium battery than the lithium iron phosphate batteries, lithium iron phosphate batteries or lithium titanate battery has more advantages. Poor safety factor, short cycle life is the key to the ternary polymer lithium battery weak link, which is restricted by the factor of safety of the large-scale configuration and large scale integrated use of the key factors. Numerous comments came to the conclusion that large capacity ternary cells hardly through safety tests, such as acupuncture and overload, this is the usual cause of large capacity battery is introducing more manganese element, and even cause the lithium iron phosphate batteries and safe use. 600 times the cycle life of lithium batteries belong to medium level is reduced, so the present stage the ternary polymer lithium battery application field is the key to POS terminals, intelligent speakers, red wine bottle opener, the children are watching, beauty equipment, lighting lamps and lanterns, mobile DVD, GPS tracking, holding a small fan battery, controller, lighting lamps and lanterns, intercom, etc
