How to choose the line of lithium battery pack

According to the different cathode materials, lithium-ion batteries are mainly divided into: LFP, LNO, LMO, LCO, NCM, and NCA. Different types of cells are used in different fields. For example: Tesla cars chooses NCA ( LiNiCoAlO2 ) cell for car battery. LFP( LiFePO4 ) usually used for home energy storage. . This is the amount of energy the battery can store. Higher capacity means the battery can store more energy and provide more operating time for the device. . The voltage and current of a battery determine the amount of power it can deliver. For the same current, higher voltage can provide more power to the device. . This is the rate at which a battery can discharge its stored energy. It determines how quickly it can deliver its stored energy. For example: If the battery capacity is 1Ah, 1C is 1A. . Energy density is a measure of how much energy can be stored in a given volume or mass of the battery. The cell with high energy density will be more compact and lighter, but it may also have a shorter lifetime and may be more. [pdf]
