In this study, nickel-cobalt-lithium LiNi0.7Co0.3O2 cathode materials are regenerated from spent lithium-ion battery cathode materials as the raw material, which not only aids in the reduction of pressure on the environment but also leads to the recycling of resources.
The thermal stability of materials was investigated using a thermal analyzer (NETZSCH DSC 200F3).

The big leg of supplied materials car is the important steel structure parts and the main stress components of material piling machine.
Therefore, to ensure that supplied materials car big leg's functions under the premise, we should determine the dimensions of supplied materials car's big leg reasonably improves the support stress condition and reduce maintenance costs of material piling machine in the future.
The big leg of cantilever side material piling machine' supplied materials car is taken as the research object in the paper.
