abstract
Lithium battery price constitutes lithium battery is the price of mainly composed of cell, protective plate, shell three parts, at the same time due to the electrical power consumption and current, the cell between the material (conventional nickel, nickel forming, copper and nickel composite, transjoint, etc.) selection will affect the cost, different connector
First, the price composition of lithium battery
The price of lithium battery is mainly composed of cell, protective plate, shell three big parts, at the same time due to the electrical power consumption and current, the cell between the material (conventional nickel, nickel, nickel, copper, span, etc.) selection will affect the cost, different connector (such as special plug, from ten yuan to thousands of yuan) may also have a greater impact on cost, and is different PACK process will also affect the cost.
Two, the influencing factors of lithium battery price
1. Selection of the electric cell
First, the selection of different material system cells will affect the price of the whole lithium battery.Lithium battery according to the different cathode materials, there will be lithium manganese oxide (3.6V), lithium cobalt oxide (3.7V/3.8V), nickel cobalt manganese oxide (commonly known as ternary, 3.6V), lithium iron phosphate (3.2V), lithium titanate (2.3V/2.4V) and other material system cell, its different material system cell, the voltage platform, safety factor, recycling, energy density ratio, working temperature, etc.
Low-temperature square aluminum shell of 3.2V 20Ah
Cell model: JD2270160CFL
Charging temperature: -20~ + 45℃
Discharge temperature: -40~ + 55℃
Maximum continuous charging current: 20A
Maximum continuous discharge current: 60A
The-40℃ supports the maximum discharge rate: 3C
-40℃ 3C discharge capacity retention rate of 70%
Second, the price of different brands will vary greatly, the total price gradient can be divided into: special cells (including ultra low temperature, high temperature, high ratio, type), Japanese (panasonic, Sanyo, SONY), Korean (samsung, LG), domestic (domestic is divided into a line (force god, gram, byd, ATL), second line, can even five, six lines), the material system and different brands of battery, price difference will be very big, and through the market brand core quality (safety, consistency, stability) is basically proportional to the price.
