The core of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC prelithium is: looking for external lithium sources, so that the whole battery formation consumes lithium ions provided by external lithium sources, rather than the consumption of positive electrode lithium ions, so as to maximize the retention of positive electrode lithium ions, and improve the total battery capacity. At present, a typical Li-enriched material is Li5FeO4, whose gram capacity is up to 700mAh/g. During formation, each molecule can release four Li+. The equation is as follows:
Li5FeO4 - > 4 li + + 4 e - + LiFeO2 + O2
The reaction is not reversible for lithium-ion batteries, as it is for positive delithium, because the O2 generated in the reaction is expelled from the battery with degassing. However, due to the high gram capacity of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC processing Li-rich materials, adding a small proportion of it into the positive electrode can add enough additional lithium ions required for the negative electrode formation. Therefore, as long as the stability of the product LiFeO2 in the electrolyte is guaranteed, It can increase the overall battery capacity.
In the concrete implementation of this scheme, if the process of mixing and coating Li5FeO4 with PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC positive active substance is explored, it can make the battery factory complete the pre-lithium without any equipment transformation. This may seem like a fool's errand, but it's often what companies love most.
