Information

Positive electrode: The cathode material of the battery accounts for 30%-40% of the cost of a lithium battery.
Negative electrode: The negative electrode material of the battery should be composed of raw materials with low relative potential of lithium electrode, with high specific volume and good crossover performance, so as to maintain the stability and reliability of mechanical equipment in the whole process of lithium intercalation.
Lithium battery electrolyte: Lithium battery electrolyte has the function of transferring positive charge between positive electrode and negative electrode, endangering specific energy, power, wide temperature application, cycle life, safety factor, etc.
The diameter of the diaphragm, diaphragm should be considered a good positive ions, maintain moisture absorption liquid and the ability to keep the ionic conductivity, dielectric strength and electronic device, to complete the mechanical equipment of plus or minus insulation protection, in addition also need to have enough puncture compression strength, tensile strength and other physical properties, corrosion resistance and enough photoelectric catalysis reliability.
Discharge process: The whole process happens to reverse the lithium-ion battery back to the forward direction, and the electronic devices enter the forward and lithium-ion battery compound according to the high-power circuit. After charging and discharging the rechargeable battery, the negative electronic component E runs from the external power supply circuit to the positive level. The positive Li-ion battery Li jumps into the lithium battery electrolyte from the negative level, climbs up the sawtooth hole in the diaphragm, swims to the positive level, and merges with the already washed electronics. The larger the charge and discharge current is, the smaller the charge and discharge capacity is and the faster the operating voltage decreases.
The whole process of charging: Driven by the electrostatic field, the lithium ion battery slides out of the normal lattice constant through the electrolyte solution and into the negative lattice constant. At the beginning of battery charging, check the working voltage of the standby rechargeable battery. If the working voltage is less than 3V, precharge the battery and the current is 1/10 of the preset current. The working voltage is increased to 3V, and the whole battery charging adjustment process is entered. The whole battery charging adjustment process is as follows: Set the current for constant current charging, and when the battery voltage rises, change to constant current charging to maintain the working voltage of battery charging. At this point, the current slowly decreases, and when the current is reduced to 1/10 of the current set, the battery is charged.
