The positive electrode: The positive electrode material of the battery accounts for 30% to 40% of the cost of lithium batteries.

The negative electrode: The negative electrode material of the battery should be composed of raw materials with a relatively low lithium electrode potential, featuring a high specific volume and good cross-crossing performance, thereby maintaining the stability and reliability of the mechanical equipment throughout the lithium intercalation process.

Lithium battery electrolyte: The lithium battery electrolyte has the function of transmitting positive charges between the positive electrode and the negative electrode, which affects specific energy, power, wide temperature applications, cycle life, safety factor, etc.

Diaphragm: The diameter of the diaphragm should take into account a good positive ion foundation, the ability to absorb liquid to retain moisture and maintain the conductivity of positive ions, as well as the dielectric strength of electronic devices to protect the positive and negative insulation layers of mechanical equipment. In addition, it needs to have sufficient physical properties such as puncture compression strength and tensile strength, corrosion resistance, and sufficient photoelectrocatalytic reliability.

The entire process of discharge: During the entire process, the lithium-ion battery happens to be reversed back to the forward direction, and the electronic components enter the forward direction and recombine with the lithium-ion battery according to the high-power circuit. After the rechargeable battery is charged and discharged, the negative electron device e operates from the external power supply circuit to the positive level. Positive lithium-ion battery li jumps into the lithium battery electrolyte from the negative level, climbs up the serrated holes on the diaphragm, swims to the positive level, and fuses with the already washed electronic components. The greater the charging and discharging current, the smaller the charging and discharging capacity, and the faster the working voltage drops.

The entire charging process: Under the drive of the electrostatic field, the lithium-ion battery slides out of the normal lattice constant through the electrolyte solution and enters the negative lattice constant. At the beginning of battery charging, the working voltage of the standby rechargeable battery should be checked. If the working voltage is less than 3V, pre-charging should be carried out first, with the current being 1/10 of the set current. When the working voltage rises to 3V, the entire battery charging regulation process begins. The entire battery charging regulation process is as follows: Set the current for constant current charging. When the battery voltage rises, switch to constant current charging to maintain the working voltage for battery charging. At this point, the current gradually decreases. When the current drops to one-tenth of the current set, the battery charges.
