Electrical charge and discharge of lithium ion secondary batteries takes place through the movement of lithium ions between the cathode and anode. Anode active materials receive lithium ions during charging, and release electrodes during electrical discharge. The following passage will introduce the production process of silicon, which is one of the anode active materials. Silicon…

In Lithium Ion Batteries, recharge and discharge occurs through the movement of lithium ions between the cathode and anode. The material that takes in and discharges the lithium ion is called active material. Methods for producing these cathode active materials will be described in this passage. The production process is split into two separate procedures.…

The following is an introduction of the production process of lithium cobalt oxide LiCoO2 LCO, which is one of the leading cathode precursors of lithium ion secondary batteries. The following process can be utilized for not only lithium cobalt oxides, but for a ternary system such as Li(NiaMnbCo1-a-b) NMC and Li(NiaCobAl1-a-b)O2 NCA as well as…

This passage will introduce the production flow of producing Iron Phosphate Lithium LiFePO4, one of the leading phosphate based cathode active materials for lithium ion secondary batteries. Recently, Olivine type cathode materials such as LiMPO4 (M: Mn, Mg, Ni) is rapidly being developed and implemented due to its cheap costs and the fact that it…
