Lead acid battery (VRLA) is a type of battery where the electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of lead-acid batteries, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; In the charging state, the main component of the positive and negative electrodes is lead sulfate.Lithium iron phosphate battery refers to a lithium-ion battery that uses lithium iron phosphate as the positive electrode material. The positive electrode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium iron phosphate is currently the cathode material used by the vast majority of lithium-ion batteries.

       During the charging and discharging process of lead-acid batteries, combustible gas hydrogen gas may precipitate. According to Appendix B of GB 50058-2014 Design Specification for Electrical Equipment in Explosive Hazardous Environments and Article 23 of the Typical Example Diagram of Hazardous Areas in Explosive Gas Environments, it belongs to the IIC classification of gas explosion environments and is the highest level of the same category. Flammable and explosive. The charging and discharging process of lithium iron phosphate batteries involves the migration of lithium ions between the positive and negative electrodes, without the production of combustible gases. Safe and reliable.

         A battery undergoes a cycle of charging and discharging, known as a cycle. Under certain discharge conditions, the number of cycles that a battery can withstand before reaching a specified capacity is called the cycle life. The number of cycles used by various batteries varies, with traditional lead-acid batteries having a cycle life of 300-500 times and lithium iron phosphate having a cycle life of over 2000 times. The factors that affect the cycle life of lead-acid batteries are firstly the performance of the product, and secondly the quality of maintenance work. Lead acid batteries need to undergo checked charging and discharging every quarter or six months; And lithium iron phosphate batteries are truly maintenance free, reducing maintenance costs.
