1. Lithium batteries are divided by appearance: square (such as commonly used mobile phone battery cells) and cylindrical (such as 18650) lithium batteries;
2. Lithium battery with aluminum case, lithium battery with steel case, soft battery;
3. Lithium batteries are divided into positive and negative electrode materials (additives): lithium phosphate (LiCoO2) or lithium manganate (LiMn2O4) battery, lithium iron phosphate battery, disposable lithium manganese dioxide battery; another branch: lithium ion LIB, polymer PLB
IV. Divided into different performances and uses:
Disposable --- Lithium manganese battery. -- 3 volt coin cell battery
High capacity (high deck) -- used in digital mobile phone products
High rate --- used in electric cars, power tools and model airplaneses
High temperature; ---miner's lamp, interior lighting, built-in machine emergency power supply;
Low temperature ---outdoor environment, northern (winter) Antarctica;
Lithium batteries are generally divided into two categories:
These are: 1. Lithium metal batteries, generally using dioxide manganese as positive electrode material. , Lithium metal or its metal alloy is used as the negative electrode material, and the battery uses non-aqueous electrolyte solution. 2. Lithium ion battery is generally a battery that uses lithium alloy metal oxide as the positive electrode material, graphite as the positive electrode material. the negative electrode material and uses a non-aqueous electrolyte. Lithium-ion batteries can be divided into categories based on their uses. The 3C lithium battery is the battery usedseen daily in our mobile phones, tablets, laptops, etc. Power lithium batteries are batteries used in new energy electric vehicles, drones and other products.
Finished batteries of 3C lithium batteries need to be tested before they can be used, mainly to test whether their performance and quality meet the qualification standards. You can choose high current shrapnel microneedle module as the connection module. Firstly, it can transmit large current, the current transmission is very stable in the range of 1-50A, and it has good connection function. be adapted to small steps. The minimum pitch value can reach 0.15mm, which is a reliable solution; third, it has an average lifespan of up to 20W and can handle high-frequency testing.
