What is the difference between lithium battery and storage battery

1. Different concepts and properties

Lithium Iron Phosphate Battery: A type of lihiutm battery made of lithium metal or lithium alloy as anode material, using a non-aqueous electrolyte solution. It relies heavily on lithium ions moving between positive and negative electrodes. In the process of charge and discharge, Li+ is inserted and uninserted between the two electrodes. During charging, Li+ is removed from the positive electrode and embedded into the negative electrode through the electrolyte. The negative electrode is in a lithium-rich state. The opposite is true for electrical discharge. Due to the very active chemical characteristics of lithium ion battery, the processing, preservation and use of lithium metal require very high environmental requirements.

Storage Battery: Storage battery is also called secondary battery. A device that converts chemical energy directly into electrical energy. It is a rechargeable battery designed to be recharged by a reversible chemical reaction, usually a Lead acid battery. After discharge, the internal active substance can be regenerated and stored as chemical energy by way of charging; To discharge, chemical energy is again converted into electrical energy. Maintenance Free Battery is a kind of electrical and chemical equipment that stores chemical energy and releases electric energy when necessary.

2. Different safety performance

Lithium ion battery: Lithium ion battery comes from the stability of cathode materials and reliable safety design. Lithium iron phosphate battery has been strictly tested for safety, and will not explode even in a violent collision. Lithium iron phosphate has high thermal stability and low oxygenation ability of electrolytic liquid, so it has high safety.

Batteries: Lead-acid batteries may explode in strong collisions, posing a threat to the life and safety of consumers.

3. Different prices

Lithium-ion batteries: Lithium-ion batteries are expensive. Lithium-ion batteries are about three times more expensive than lead-acid batteries. Combined with the service life analysis, the service life of lithium ion battery is still longer for the same cost.

4, Green environmental protection is different

Lithium ion battery material without any toxic and harmful substances, the world is considered green battery, the battery no matter in production and use are pollution-free, in line with the European RoHS regulations, for the green battery.

There is a large amount of lead in lead-acid batteries, which will pollute the environment if not handled properly after abandonment.

5, The use of cycle life

The service life of lithium-ion battery is longer, and the service life of storage battery is relatively short. The number of cycles of lithium-ion batteries is generally about 2000-3000.

Battery cycles are about 300-500 times.

6. Weight energy density

Lithium ion battery energy density is generally 200~260wh/g, lithium ion battery is 3~5 times of lead acid, which means that under the same capacity, lead-acid battery is 3~5 times of lithium ion battery, so in the energy storage device lightweight, lithium ion battery occupies an absolute advantage.
