  Lead-acid batteries are a mature battery technology that mainly uses lead and lead oxide as electrodes and sulfuric acid as an electrolyte. Their advantages include: Low cost : Lead-acid batteries have a lower manufacturing cost than other types of batteries. High current output : More suitable for high power requirements, such as car starting. Reliability : Lead-acid batteries perform well in extreme temperatures. However, lead-acid batteries also have disadvantages, such as low energy density, heavy weight, and short cycle life. They are widely used in automobiles, UPS systems, and solar energy storage. Nickel-metal hydride batteries (NiMH) are a common rechargeable battery that mainly consists of nickel oxide and hydrogen storage alloy. Their advantages include: Higher energy density : Compared with lead-acid batteries, nickel-metal hydride batteries have higher energy density and lighter volume and weight. Environmental protection : NiMH batteries do not contain harmful heavy...

  Lithium iron phosphate (LiFePO₄) batteries are widely used in many fields due to their high safety, long life and environmental friendliness. The following are some of the main use scenarios of lithium iron phosphate batteries: 1. Electric vehicles (EV) Lithium iron phosphate batteries are widely used in electric vehicles (EV) and plug-in hybrid electric vehicles (PHEV), especially in situations where safety is required. Because lithium iron phosphate batteries have a long cycle life and a lower risk of thermal runaway, they have become the preferred battery type for vehicles such as electric buses, logistics vehicles, and passenger cars. 2. Energy storage system Lithium iron phosphate batteries are widely used in home energy storage, commercial energy storage, and large-scale grid energy storage systems. They are used in solar photovoltaic systems and wind power generation systems to store excess energy so that it can be released when power demand peaks or energy supply is insuf...
