The capacity of LFP cells covers the from 40Ah~302Ah.
LFP40Ah is power type of cell, which is suitable for the application that request high power charge or discharge rate, such as motorcycle, AGV etc. Other capacity of LFP cells are energy type of cells, which are appropriate for the projects of requiring continuous charge or discharge rate at 1C projects.
LFP50Ah, LFP100Ah and LFP135Ah is mainly applied in househould energy storage and low speed vehicles.
LFP205Ah and LFP230Ah with close dimension, and LFP280Ah and LFP302A and deep cycle LFP280Ah with almost same dimension are suitable for forklifts, electric bus, and trucks applications.
In addition, deep cycle LFP280Ah is designed specially for energy storage demand at the 6000times cycle life.
The cycle life of lithium battery cells varies associating with the testing condition of cycle life, including temperature, DOD(deepth of discharge), remaining battery capacity, charge and discahrge current. Common testing condition of cycle life is to charge and discahrge at 0.5C or 1C current rate under 100% DOD at the room temperture, the cycle life number is recorded until remaining battery capacity is less than 80%. The cycle life increase along with shallow DOD, and low current rate, and high capacity loss. Terefore, Litihium Storage suggested clients to pay attention to the testing condition of cycle life. In addition, the reliability of cycle life data from battery manufactuer is also relevant with the reputation of battery brand.
LTO excels in safety, cycle life and charging rate, but the low energy density and high cost limit the application in electric vehicles.
LMO is moderate in overall performance; most LMO battery blend with NCM to improve the energy density and prolong the cycle life. So typically, LMO (NMC) is chosen for electric vehicles application but existing limited growth potential.
LFP has excellent performance of safety and long cycle life but moderate energy density. LFP is primarily used in energy storage and the special vehicles which have a low requirement to battery energy density, high demand for battery safety performance.
NMC is the most favorable chemistry for many passenger vehicles manufacturers because of contribution to long driving distance benefiting from high energy density of NMC but less cycle life than LFP . The three materials of Nickel, Manganese and Cobalt effectively can be blended to output a wide of performance, which includes NMC111, NMC532, NMC622 and the newest NMC811. However, there are a lot of debates about the safety of high Nickel lithium ion battery.
NCA is consist of three materials of Nickel, Manganese and Aluminum, typically 80% Nickel and 15% Cobalt, but 5% aluminum as opposed to Manganese. NCA is also expected to another dominate customer requirements for the foreseeable future because of the vehicle performance success of Tesla electric vehicle combined by Panasonic cylinder batteries and Tesla's excellent battery management system.
