Do you know the important difference between lithium ion batteries and lithium batteries?

Lithium-ion battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. 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-ion batteries have not been used for a long time. With the development of science and technology, lithium-ion batteries have now become the mainstream. Lithium ion batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance-price ratio are superior to those of lithium-ion batteries. Lithium battery core article Lithium battery core rechargeable battery removal protection circuit board is the battery cell. The difference between lithium batteries and traditional lithium-ion batteries lies in the production process. Lithium-ion battery core is a single, enclosed electrochemical device composed of a positive electrode and a negative electrode with a potential difference between the two electrodes. It is the storage part of the rechargeable battery. , The quality of lithium batteries directly determines the quality of rechargeable batteries. The batteries are divided into three types: aluminum shell batteries, soft-pack batteries, and cylindrical batteries. Generally, mobile phone batteries use aluminum shell batteries, Bluetooth and other digital products mostly use soft-pack batteries, and laptop batteries use a series-parallel combination of cylindrical batteries. The energy density of lithium batteries is higher, so under the same capacity, the volume of lithium batteries is smaller and the weight is lighter. At the same time, the lithium battery cell can be made into any shape, which makes the finished product more free in the shape design, greatly improves the flexibility of the mobile power supply, and has outstanding performance in terms of safety. Although the price is higher than the 18650 battery cell, it has become More and more products use lithium batteries, which can be said to be the future development direction. The difference between lithium ion battery and lithium battery ▲Lithium ion battery is mainly composed of two blocks, battery cell and protection board (PCM), protection board is mainly composed of protection chip (or management chip), MOS tube, resistor, capacitor and PCB board, etc. ; The battery cell is equivalent to the heart of a lithium-ion battery, and the management system is equivalent to the brain of a lithium-ion battery. The battery cell is mainly composed of positive electrode material, negative electrode material, electrolyte, diaphragm and shell. Lithium batteries are an important part of lithium-ion battery packs. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
