Gas production is a problem that LITHIUM ion batteries must face in the process of use. The gas production of lithium ion batteries is usually due to the decomposition of the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal electrolyte on the surface of the positive and negative electrodes. Or some impurities on the surface of the cathode material (such as Li2CO3) break down under high voltage. Gas production not only causes the soft-packed lithium-ion battery to bloat, creating bubbles that accumulate inside the battery cell,
It can also cause problems such as bubble edge lithium analysis and battery capacity decline, so gas production is an important content of lithium ion batteries. High temperature storage will aggravate the gas production of LITHIUM ion battery, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal, different cathode materials will also affect the gas production of lithium ion battery, LCO, NCM and NCA materials in the high temperature storage layer of gas production was analyzed.
The analysis shows that the gas production phenomenon of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC for iron removal is more serious than LiCoO2 in the early stage of high temperature storage, which is mainly affected by impurities such as LiOH and Li2CO3 on the surface of the triene material. However, with the increase of storage time, The gas production of LCO is higher than that of ternary materials.
