Energy storage lithium battery cell selection
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 choos. 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. 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. 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 discharge 1h to complete the discharge, 5C is.

Lithium battery cell grouping and pairing
If the cell manufacturer can deliver cells with a proven quality history of OCV within +/-0.02V then you will be able to assemble and charge these cells without gross balancing. However, you will need to consider a few things: 1. cell manufacture, formation, ageing end of line testing all have reporting and metrics 2. This is what you are probably trying to avoid as it can take hours or even days for the pack balancing to remove large SoC differences. An SoC difference of 10% on a 100Ah cell will take 100 hours to remove with a 100mA balancing. This is the approach used by the satellite industry and adopted by motorsport. The cells undergo a number of checks from visual inspection, capacity and internal resistance measurement. Prior to assembling the battery packs you can charge/discharge all of the cells to a defined voltage. This ensures all of the cells are matched in SoC prior to assembly.
