Lithium -ion battery materials will expand and shrink in volume in lithium -ion repeatedly embedded. Long -term volume changes may cause the material structure to collapse.
In the lithium -tinylite -lithium manganate material, as the cycle is carried out, the material will have a distortion effect, causing the oxygen octopus to deviate from the ball symmetry and distort it into a deformed octopus. When defects in the material structure, collapse will occur during repeated contraction and expansion. When LIMN2O4 was embedded in 3V, it became Li1+XMN2O4 after lithium, and Li entered the 16C bits of the octopus, making the MN3 ﹢ concentration greater than MN4 ﹢ "concentration, which led to a decrease in structural symmetry. When coexisting, the structure is not compatible, and the electrode material particles cannot be touched well. The volume of li ﹢ is difficult to increase, resulting in increasing irreversible capacity loss. In addition, when the Limn2O4 is in depth or high mortar discharge, the surface of the electrode is on the surface of the electrode. When the lithium ion is quickly embedded in lithium ion, the dynamics is limited, and the Jahn-Teller distorted Lizmn204 will be generated on the surface. The dynamic science is limited when the lithium ion is embedded, and the JAHN-Teller distorting the LIZMN2O4 will be generated on the surface. Unstable, dissolved in the form of MNO, which leads to an increase in the proportion of N (li)/n (mn) in lithium manganese oxides. At the same time, it is accompanied by MN3 ﹢ oxidation to MN4 ﹢ "and manganese atoms. LI2MNO3 from spinel -like to layered structure. The LIZMNO3 generated is strong in thermal stability and has no electrochemical activity, causing irreversible capacity loss.
The electrochemical performance of the lithium -ion battery at different temperatures found that the battery experienced a fast capacity attenuation at high temperature. The anatomical analysis of the battery found that a small amount of iron is detected in the battery electrolyte after circulation. Elements exist. Their research found that the litteria negative electrode carried out with the cycle. Whether it was the micro -scale peeling the surface of the grain, the graphite grain was fine, or the macroex polar tablet was slightly cracking, and the graphite and the collecting flow was the macroex. The layered stripping will cause the mechanical instability of the graphite surface SEI membrane, which will cause losses of active lithium and eventually lead to the attenuation of the battery capacity. Therefore Due to the attenuation of negative physical properties.
