Storage battery: A storage battery is also called a secondary battery. It is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to be recharged through a reversible chemical reaction, usually a lead-acid battery. After discharge, the internal active material can be regenerated by charging - storing electrical energy as chemical energy; and converting chemical energy into electrical energy again when it needs to be discharged. A battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.
Lithium battery: It is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It mainly relies on lithium ions to move between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes; during charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; during discharge, the opposite is true. Due to the very active chemical properties of lithium batteries, the processing, storage, and use of lithium metal have very high environmental requirements. The positive and negative electrodes of the lithium battery are lithium cobalt oxide/lithium iron phosphate/lithium manganate, graphite, and organic electrolyte.
The positive and negative electrodes of lead-acid batteries are lead oxide, and metal lead and the electrolyte is concentrated sulfuric acid.
The lithium battery has no memory effect, the battery can be charged and discharged at any time, the self-discharge of the battery is low, and the battery can be stored for a long time; the power is strong, and it can be charged and discharged quickly.
The solar battery has a memory effect and cannot be charged and discharged at any time; there is a serious self-discharge phenomenon, and the battery is easy to be scrapped after being put on hold for a period of time; the discharge rate is small, and it cannot be discharged with a large current for a long time.
