lithium batteries
A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It differs from rechargeable lithium-ion batteries and lithium-ion polymer batteries. The inventor of the lithium battery is Thomas Edison. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental controls. Therefore, lithium batteries were not widely used for a long time. With the development of microelectronics technology at the end of the 20th century, the increasing miniaturization of devices placed higher demands on power supplies. Lithium batteries subsequently entered a stage of large-scale practical application.
Product Categories
Lithium batteries are generally divided into two main categories:
Lithium metal batteries: Lithium metal batteries generally use manganese dioxide as the positive electrode material, lithium metal or its alloy metal as the negative electrode material, and a non-aqueous electrolyte solution.
Lithium-ion batteries: Lithium-ion batteries generally use lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and non-aqueous electrolyte.
Although lithium metal batteries have a high energy density, theoretically reaching 3860 watts per kilogram, their unstable nature and inability to be recharged prevent them from being used as reusable power batteries. Lithium-ion batteries, on the other hand, are being developed as the primary power battery due to their rechargeability. However, the different elements incorporated into the cathode materials result in significant differences in performance across various aspects, leading to increased debate within the industry regarding cathode material development strategies.
The most commonly mentioned power batteries are lithium iron phosphate batteries, lithium manganese oxide batteries, lithium cobalt oxide batteries, and ternary lithium batteries (ternary nickel-cobalt-manganese).
conductive coating
Conductive coating, also known as pre-coating, usually refers to a conductive coating applied to the surface of the positive electrode current collector—aluminum foil—in the lithium battery industry. Aluminum foil coated with conductive coating is called pre-coated aluminum foil or simply coated aluminum foil. Its earliest experiments in batteries can be traced back to the 1970s. In recent years, with the development of the new energy industry, especially lithium iron phosphate batteries, it has become a popular new technology or material in the industry.
Some lithium-ion batteries have a third wire that is a temperature protection wire, while others have a battery information verification wire (for example, it should trigger an alarm if a non-original battery is replaced).
Lithium-ion batteries consist of a battery and a protection board. Three wires only appear on the protection board; the battery itself always has only two wires.
There are two types of lithium-ion batteries. The one with a voltage of 3.7V is obviously a non-aluminum iron phosphate battery, which can be directly replaced.
Replacement is very simple (note the positive and negative terminals):
1. Remove the original battery packaging, then use a soldering iron to separate the protection board from the battery.
2: Similarly, remove the protection board from your new battery and connect the battery to the old protection board.
Connect P+ and P- to the output. Connect B+ to the positive terminal of the battery cell and B- to the negative terminal. If multiple cells are connected in series, connect the negative terminal of B1 and the positive terminal of B2 together, and so on, with the negative terminal of the last cell connected to Bn-. Solder the wires first, then connect the batteries last, making sure not to connect them incorrectly. If there is no output after completion, remember to use a charger to charge and activate the battery at the charging interface from P+ and P-.
