Lithium ion battery and lead acid battery, nickel cadmium battery

Source: 2020 - 04 - 12 20:55 hits: lithium ion battery and lead acid batteries, nickel cadmium battery comparison of railway vehicle emergency standby power supply in our country mainly adopts nickel-cadmium batteries, part of the old models still use lead-acid batteries. The main problem with the battery weight is big, big volume, maintenance trouble, need a lot of form a complete set of equipment maintenance and repair personnel configuration. The heavy metal in battery will cause harm to the environment. In the process of production, use and destruction produced a lot of heavy metal lead and cadmium. Heavy metal ions serious destruction of ecological environment not only, still can enter human body through water, air and food, lead to poor health. Due to the effect of China's population and employment environment, the distribution of the railway is very broad, a lot of the cell number of the train is also very big. In quite a long period of time, however, these batteries in a suspended state for a long time, without the proper process conditions, in the long run, it will be in China already fragile environment cause more serious pollution of valve-control sealed lead-acid battery in table 1, the whole sintering alkaline nickel cadmium batteries, lithium-ion battery performance comparison table. Table 2 battery performance comparison table 2 spare battery performance battery valve control type sealed lead acid battery ( Advanced lead-acid battery) The sintering of cadmium nickel battery ( The best performance of nicad batteries) Iron phosphate lithium-ion battery ( A new generation of lithium ion battery) Battery model TFM - 100 gnc - 100年奖学金 Rated voltage/V 2 100 monomer. 0 v 1。 2 v 3。 2 v rated capacity/Ah Ah Ah Ah 100 100 100 can volume per watt hour ( dm3) - 1, 85, 71, 206. 5公斤, 1 29. 1, 32, 106. 70. 2C( 20A) 85, 100, 110 at room temperature (1 c/Ah 100A) Discharge performance in 108, 91. 675C( 500A) There is no 58. 33 100 / Ah 0 discharge performance at low temperature. 2c ( 20A) no 801001C( 100A) There is no 57. 5 95 heat discharge performance/Ah no 55 ℃ high temperature discharge performance of 100 a capacity of 112 Ah charge/discharge uniformity Ah, performance is better, aside the charging status of 28 days of 96 Ah self-discharge, aside the charging status of 28 days of 80 Ah low self-discharge, initial capacity: 110, full state from 28 days Ah cycle life of 105 / week ( Times) The shortest life expectancy -- 180 short, shallow charge-discharge is not less than 550 longest service life and can be carried out depth charge is almost 4000 times, 99 ah lead-acid battery in environmental protection lead is harmful to human body, environmental pollution, Lead-acid batteries containing cadmium) Cadmium nickel battery cadmium is harmful to human body, the pollution of the environment used in lithium ion battery material is harmless to human body, belong to the green environmental protection of power use maintenance acid corrosion and wire connection parts, yes on a regular basis to wipe, maintenance is more complicated. Effect of alkali fog climbing alkali corrosion, and regularly adding distilled water to replace the electrolyte, maintenance is the most boring, the intensity of labor is big, poor working environment battery sealing, convenient maintenance so the advantage of lithium ion battery is the smallest, lightest weight, high and low temperature multiplier discharge performance is the best, the longest service life, the most environmental protection, maintain the simplest.
