Source: 2020 - 03 - 26 'hits: ternary lithium battery and lithium iron phosphate battery energy density which is better? The energy density of lithium iron phosphate battery monomer in wh/kg - 90 120 wh/kg, and the ternary lithium battery monomer reached 200 wh/kg to arrange energy density as well as you, seems to be the advantage of the ternary lithium battery energy density is relatively accurate, it is also in a few years to collect online actual reasons of ternary lithium battery production line, with Japan and South Korea ternary lithium battery skills to keep goal, injected strong beliefs into the shopping center. In terms of safety, the ternary lithium battery liquid electrolyte, easy combustion and explosion in the process of long-term use of prone to 'thermal runaway. In the process of charging, lithium dendrite growth is easy to puncture the cracks, cause short circuit batteries, form the safe hidden trouble. Lithium iron phosphate battery encapsulation with high temperature resistance, safety, quiet strong sex, better reincarnation, etc. Temporarily on the market for lithium cobalt oxide, lithium manganese acid batteries are less common, at least the following five kinds of lithium iron phosphate battery cheap: security is higher, longer service life, does not contain all of the heavy metals and rare metals ( Lower the cost of materials) Charging, support, working temperature field. Defect is the lithium iron phosphate battery has some natural defects, such as vibration density and compaction density is very high, guide the lithium ion battery energy density is relatively low; Cost of material preparation and battery manufacturing cost is higher, battery low yield, poor penetration; Poor product everywhere; Knowledge property right. The ternary lithium battery energy density is high, the renewable natural is better than common cobalt acid lithium. The nominal voltage of battery has already reached 3. 7 v, because the formula is not broken, the structure is complete. Defect: three yuan energy lithium battery is an important material, aluminum nickel and cobalt acid lithium batteries, nickel cobalt manganese acid lithium battery, etc. , because of high temperature aluminum nickel and cobalt alloy structure is not quiet, high temperature and poor safety guidance and pH is too high, easy to make a single gas, then stimulate the damage, temporary cost is very high. The above is the lithium iron phosphate battery and lithium battery three is the comparison of life, the difference between the two original life is not much, nature also has some of the different development space, is each lithium battery consumer cannot break the development of new products, to fill the defect and have no feet, can stand firm in the market.
