What are the differences between power lithium-ion batteries and storage batteries?

1. The materials are different. The power lithium-ion battery plates are mostly lead-calcium alloy, and the batteries for starting are mostly lead-antimony alloy. 2. The discharge time is different. The power lithium-ion battery can be discharged for several hours with a small current, and the discharge depth is very deep. The start-up battery has a short discharge time, but runs a large discharge current, several hundred amperes. 3. The electrolyte concentration is different. In order to run farther, many people increase the electrolyte concentration of power lithium-ion batteries to 1.31. In fact, the battery is very easy to vulcanize and make the plates inactive. The standard concentration of electrolyte for starting the battery is 1.28, under which a larger discharge current can be obtained, which makes the car easy to start. 1. The materials are different. The power lithium-ion battery plates are mostly lead-calcium alloy, and the batteries for starting are mostly lead-antimony alloy. 2. The discharge time is different. The power lithium-ion battery can be discharged for several hours with a small current, and the discharge depth is very deep. The start-up battery discharge time is very short. First, when the battery is new, the battery capacity is tested with a discharge meter. Generally, the capacity of the power lithium-ion battery is about 1000-1500mAh; while the capacity of the ordinary battery is above 2000mAh, there is It can reach 3400mAh. 3. Discharge power is different. A 4200mAh power lithium-ion battery can discharge the power in just a few minutes, but ordinary batteries can't do it at all, so the discharge capacity of ordinary batteries is completely incomparable with power lithium-ion batteries. The biggest difference between a power lithium-ion battery and an ordinary battery is its large discharge power and high specific energy. Since the important purpose of power batteries is the energy supply for vehicles, they have higher discharge power than ordinary batteries. Fourth, the application of different applications to provide driving power for electric vehicles is called power lithium-ion batteries, including traditional lead-acid batteries Batteries, nickel-metal hydride batteries and the emerging lithium-ion power lithium batteries are divided into power-type power lithium-ion batteries (hybrid vehicles) and energy-type power lithium-ion batteries (pure electric vehicles); mobile phones, laptops and other consumer electronics products The lithium batteries are generally collectively referred to as lithium batteries to distinguish them from the power lithium-ion batteries used in electric vehicles.
