Do you know how to charge and discharge lithium batteries?

During the charging and discharging process of the lithium battery, when the battery passes a certain amount of electricity, a certain amount of substances are generated and disappeared in the plate and electrolyte, which means that the greater the amount of substances generated and disappeared during the charging and discharging process. The more power it passes through, the larger the battery capacity. Conversely, the less power it passes, the smaller the battery capacity. This means that the capacity of a lithium lead-acid battery depends on the number of active materials participating in the chemical reaction. The most effective way to increase the number of active substances participating in chemical reactions is to increase the area of u200bu200bthe plate. Due to the increase in the area of u200bu200bthe electrode plate and the larger connection area of u200bu200bthe electrolyte, the battery capacity is larger, which also increases the volume of the battery. Therefore, the larger the battery volume, the larger the capacity. During the discharge process of lithium batteries, the active material lead dioxide of the positive electrode and the active material metal lead of the negative electrode both react with the sulfuric acid electrolyte to produce lead sulfate. This reaction is called the double sulfation reaction in electrochemistry. When the lithium battery is just discharged, the lead sulfate converted into the positive and negative active materials is a kind of crystalline material with loose structure and fine crystals, and the degree of activity is very high. During the charging process of the lithium battery, the loose and dense lead sulfate on the positive and negative electrodes will become lead dioxide and metallic lead again under the use of external charging current, and the lithium battery will be in a fully charged state again. It is this reversible electrochemical reaction that enables lithium batteries to store and release electrical energy.
