lithium battery
A primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution, which is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. The inventor of the lithium battery was Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the twentieth century, the number of miniaturized devices is increasing, which puts forward high requirements for power supply. Lithium batteries have then entered a large-scale practical stage.(Lithium - Ion Battery Equipment)
product category
Lithium batteries are usually divided into two categories:
Lithium metal battery: Lithium metal battery generally uses manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and uses a non-aqueous electrolyte solution.
Lithium-ion batteries: Lithium-ion batteries generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and use non-aqueous electrolytes.
Although lithium metal batteries have a high energy density, they can theoretically reach 3860 watts/kg. However, because its nature is not stable enough and cannot be charged, it cannot be used as a power battery for repeated use. The lithium-ion battery has been developed as the main power battery due to its ability to be repeatedly charged. However, due to the combination of different elements, the composition of the cathode material varies greatly in performance in various aspects, resulting in increased disputes over the cathode material route in the industry.
Usually, the power batteries we talk about the most mainly include lithium iron phosphate batteries, lithium manganate batteries, lithium cobalt oxide batteries and ternary lithium batteries (ternary nickel cobalt manganese).
conductive coating
Conductive coating is also known as pre-coating. In the lithium battery industry, it usually refers to a layer of conductive coating applied to the surface of the positive electrode current collector, the aluminum foil. The aluminum foil coated with the conductive coating is called pre-coated aluminum foil or simply coated. Layered aluminum foil, its earliest experiments in batteries can be traced back to the 1970s. In recent years, with the development of new energy industry, especially lithium iron phosphate batteries, it has become a popular new technology or new technology in the industry. Material.
For some lithium-ion batteries, the third is the temperature protection line, and some are the battery information check line (for example, if the non-original battery is replaced, an alarm will be prompted).
Lithium-ion batteries are all batteries + protection boards. The 3 wires will only appear on the protection board, and the battery will always only have 2 wires.
There are two kinds of lithium-ion batteries, the obvious 3.7V is non-iron-aluminum phosphate, which can be replaced directly.
The replacement is very simple (note the positive and negative):
1: Remove the packaging of the original battery, and then separate the protective plate and the battery with a soldering iron.
2: Similarly, remove the protective plate of your new battery and connect the battery to the old protective plate.
P+ and P- are connected to output. B+ is connected to the positive electrode of the cell, and B- is connected to the negative electrode. If it is a series of multiple cells, the negative electrode of B1 and the positive electrode of B2 are connected together, and so on, the negative electrode of the last battery is connected to Bn-. Solder the wires first, connect the battery last, don't make a mistake. If there is no output after completion, remember to use the charger to charge and activate the charging interface from P+ and P-.
