Lithium iron phosphate batteries these seven advantages: you know what?

Source: 2020 - 04 - 10 so he hits: 1 time advantage. The improvement of safety performance of lithium iron phosphate crystals in p - O key is stable, not easy to decompose. Even in the case of high temperature or overcharge, the structure will not collapse like lithium cobalt oxide to produce heat or forming strong oxidizing substances, therefore has good security. According to the report, in practice, in the needle or short circuit experiments found a small amount of sample burns, but not an explosion. In the overcharge experiments, however, still can appear after the high voltage charging explosion phenomenon, its discharge voltage is several times their own discharge voltage. But compared with the ordinary cobalt liquid electrolyte of lithium batteries, the overcharge security had the very big enhancement. 2. Longevity of lithium iron phosphate battery refers to the lithium iron phosphate as the anode material of lithium ion batteries. Long life cycle life of lead acid battery is about 300 times, 500 times the maximum, and lithium iron phosphate battery cycle life of more than 2000 times, using the standard charge ( 5 hour rates) Can reach 2000 times. Lead-acid batteries of the same quality with 'new six months, six months old, maintenance and maintenance of six months', up to 1 ~ 1. 5 years, and lithium iron phosphate batteries, under the same condition, the theory of life will reach 7 ~ 8 years. Overall, this performance than lead acid battery is the theory more than four times. Large current discharge can be large current fast charge and discharge, 2 c in the special charger, 1. 5 c make battery charging 40 minutes, starting current can be up to 2 c, but the performance of the lead-acid battery have no such. 3. High temperature peak electrical performance of the lithium iron phosphate can reach 350 ℃ 500 ℃, and lithium manganese acid lithium cobalt oxide and electric peak only about 200 ℃. Working temperature range ( - 20c - 75C) , electric heating peak lithium iron phosphate with high temperature resistant properties of up to 350 ℃ 500 ℃, lithium cobalt and lithium manganese acid and acid only at about 200 ℃. 4. Continue with large capacity batteries, battery capacity rapidly falling below the rated capacity, this phenomenon is called memory effect. For example, nickel metal hydride batteries and nickel-cadmium battery has a memory function, and lithium iron phosphate batteries would not have this kind of phenomenon. No matter in what state, it can be used when charging, and don't have to remove the batteries to recharge. 6. Light weight of the same size of lithium iron phosphate battery is two-thirds the size of lead-acid battery, a third of the lead-acid battery weight. 7, the environmental protection of lithium iron phosphate batteries generally do not contain any heavy metals and rare metals ( Nimh batteries need to rare metals) , non-toxic ( Through the SGS certification) , no pollution, in line with European RoHS regulations for absolute green battery license. The main reason for the favor by industry as a result, the lithium battery is environmental protection. Therefore, the battery was listed in '863' national '15' high technology development planning, become the focus of the state shall encourage and support development projects. With China's accession to the wto, China's electric bicycle exports will grow rapidly. In Europe and the United States, the electric bicycle has requires the use of non-polluting batteries. But there are also the expert points out, the environmental pollution caused by lead acid battery is the enterprise in the process of the production process is not standard and recycling. Similarly, lithium battery good things belong to the new energy industry, but it is also unable to avoid the problem of heavy metal pollution. Such as lead, arsenic, cadmium, mercury and chromium metal materials could be released into the dust and water. The battery itself is a kind of chemicals, so there are two possible pollution: one is the process of production engineering in feces pollution; Secondly, after waste battery pollution.
