Lithium battery is a battery of lithium robot battery metal or lithium alloy as negative electrode and non aqueous electrolyte solution. The earliest lithium battery came from the great inventor Edison, using the following reaction: Li+MnO2=LiMnO2 reaction is redox reaction, the discharge from the chemical properties of lithium metal is very active, The processing, preservation and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not been used for a long time. Now lithium batteries have become the mainstream.
Lithium ion battery (Lithium battery) refers to the battery containing lithium (including lithium metal, lithium alloy, lithium ion, lithium polymer) in the electrochemical system. Lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are usually non rechargeable and contain metallic lithium. Lithium ion batteries do not contain lithium and can be charged.
The technology of lithium battery is very strict and complex. Here, we can only briefly introduce some of the main processes.
Method 1. The special solvent and adhesive of pulping are mixed with the positive and negative active substances of powder. After mixing and mixing at high speed, the slurry is made into positive and negative substances.
Method two. The coating is evenly coated on the surface of the metal foil and dried to make positive and negative pole pieces.
Method three, the assembly is assembled according to the order of the positive pole - diaphragm - negative electrode - diaphragm from top to bottom.
Method four. The battery charge and discharge test is carried out with a special battery charging and discharging equipment. Every battery is tested and qualified product battery is screened out.
