Which type of battery is more suitable for the production of energy storage batteries?

The advantages and disadvantages of lead-acid batteries The maintenance-free battery has lead as the negative electrode, lead dioxide as the positive electrode, and a sulfuric acid solution as the electrolyte. Its important material determines that the durability must be poor, because lead sulfate will appear during operation, and these substances will gradually sulfide the electrode plates and affect the charge and discharge efficiency; the electrolyte will slowly evaporate during use, and no matter how it is adjusted in the later period ( Adding water) is difficult to balance to the best condition. Lead-acid batteries are most commonly used as starting power supplies for automobiles. In addition, a large part of large-scale energy storage currently uses lead-acid batteries. Lead-acid batteries are inexpensive and have stable and safe performance. They are better than lithium batteries in normal use environments. It is safer. Ruiran has a life span of only about 300 times, but it is still favored by many users. Advantages and disadvantages of lithium iron phosphate batteries The advantages of lithium iron batteries are first of all safety and environmental protection. The metal materials used in their manufacture are not heavy metals like lead, and the electrolyte is almost zero pollution. The thermal runaway temperature of this kind of battery in operation is very high (hundreds of degrees Celsius), and the special mechanism can withstand impact and puncture to ensure no fire, which is more reassuring than lead-acid batteries as storage batteries. The second advantage of lithium iron battery is its small size, low weight and high energy density. The capacity of a lithium iron phosphate battery pack with the same weight will be 3 to 4 times that of a lead-acid battery. Therefore, it does not take up too much space and is lighter than lead-acid batteries. These two points are also the absolute advantages of iron batteries. However, the advantage of playing a decisive lead is not the above points: the complete charge and discharge can be used about 2000 times, and the SOC still has a margin of 60% to 70% is the absolute advantage. Which type of battery is more suitable for production energy storage batteries? 1. Lead-acid battery energy storage battery has a long history of using lead-acid battery as energy storage battery. The important reason is that lead-acid battery was invented earlier and the technology is relatively more mature. Of course, its cheap manufacturing cost is also the most popular factor. One of them, but it also has great disadvantages. For example, the energy density per unit volume is the lowest, but the weight is the heaviest. In addition, it is relatively small in terms of supply rate discharge, and the supply power often cannot meet the demand. One is that its manufacturing materials are very harmful to the environment and the human body. Under the country's environmental protection and sustainable development, it is constantly being replaced by the application of lithium-ion batteries. 2. The use of soft-packed polymer lithium-ion batteries for energy storage batteries From the economic benefits of energy storage batteries, the use of soft-packed polymer lithium-ion batteries is the most expensive, and the safety performance is also the most unstable. This is why the batteries used in many new energy vehicles are not polymer lithium-ion batteries. Despite this, it is more ideal to choose polymer lithium-ion batteries in some energy storage batteries that are more lightweight. For example, for some electronic equipment for field exploration or work, the energy storage battery that supplies backup power is required to be as light as possible in terms of weight. Therefore, polymer lithium-ion batteries are not an ideal choice for energy storage batteries used in ordinary life. 3. The use of lithium iron phosphate batteries in energy storage batteries may be the most widely used lithium iron phosphate battery in the field of energy storage battery applications in the future. Why is this? Let's first understand the advantages of various aspects of lithium iron phosphate batteries. First of all, in terms of temperature resistance, the lithium iron phosphate battery is the most high temperature resistant battery among all energy storage batteries, laying a certain foundation for safety and stability. Then in terms of supplying high-current discharge, although it is slightly worse than polymer lithium-ion batteries, it is much better than lead-acid batteries. Therefore, the batteries used by many smart cargo trucks or robots used in warehousing and logistics are basically lithium iron phosphate batteries. . Again in terms of environmental protection, lithium iron phosphate batteries are environmentally friendly and non-polluting. They are manufactured from a wide range of raw materials and are a good product for sustainable development. Finally, in terms of electrochemical performance, such as battery capacity, energy density, cycle life, etc., they are far better than lead-acid batteries.
