A lithium battery cell is the smallest unit of a battery. There are several types of classification of lithium battery cells from shape, chemistry of positive materials, and battery C ratings.
Shape: Cylinder, Pouch, Prismatic
Lithium Storage focuses on the prismatic type of lithium battery cells.
Chemistry of positive materials: lithium iron phosphate (LFP), lithium nickel cobalt aluminum oxide（NCA）, lithium nickel manganese cobalt oxide (NCM) lithium manganese oxide (LMO) and Lithium tantalite oxide (LTO)
Lithium Storage concentrates on the LFP and NCM chemistry both types of lithium battery cells.
Battery C ratings: energy cells and power cells
Energy cells are designed to deliver constant charge and discharge current in the long-term period, generally continuous C rating less than 1~2C. Power cells are designed to support charge and discharge current at a high rate for meeting the load application requirement.
Lithium Storage has both energy cells and power cells.
Mass production leads to higher accuracy and standardization in lithium battery cell production. This is beneficial to ensuring consistency of lithium battery cells in performance and avoiding the quality risk from interrupted production and batch production. Currently, the current production capacity is 26GWh, 17 production lines, and 50GWh is under construction.
the adoption of MES and ERP systems makes the retroactive realization from raw materials to the finished products.
Lithium Storage applies the framework provided by the ISO 9001: 2015 and IATF16949:2016 standards to monitor and measure quality management processes.
