What we usually call "lithium batteries", in a strict sense, should be called lithium-ion (Li-ion) batteries. Lithium (Li) batteries and lithium ion (Liion) batteries are two different batteries. The earliest lithium batteries are dangerous when used, and there are often cases of burning and bursting during charging. This is because lithium is a relatively active metal element and is not safe to use. Lithium-ion battery (Li-ion) is a substitute for lithium, which is a substitute for lithium batteries. Its anode is composed of lithium active compound, usually lithium cobalt oxide (LiCoO2), and the negative electrode is sucked. A special molecular structure of lithium that holds lithium ions.
 

Battery memory effect
The battery memory effect is the automatic tendency of the battery to automatically maintain this particular duty cycle. This phenomenon first appeared in nickel-cadmium batteries. If the battery is not exhausted, the battery will show less and less power as the number of uses increases, so it is necessary to recharge the battery each time. Later nickel-metal hydride batteries have no obvious memory effect, but they still need to be fully charged and discharged frequently to maintain their normal storage capacity. Therefore, some nickel-hydrogen battery chargers provide the function of charging after discharge. Lithium batteries basically have no memory effect of nickel-cadmium batteries, and the principle of memory effect is crystallization, which is hardly produced in lithium batteries. However, the capacity of lithium-ion batteries will still decrease after repeated charge and discharge, which is complicated and diverse. Mainly the change of the positive and negative materials themselves. From the molecular point of view, the hole structure containing lithium ions on the positive and negative electrodes will gradually collapse and block; from the chemical point of view, the positive and negative materials are reactively passivated, and the side reaction is stable. Other compounds. Physically, the positive electrode material gradually peels off, and finally, the number of lithium ions in the battery that can freely move during charge and discharge is finally reduced.
