In application,lithium-ion cells undergo expansion during *** mechanical behavior and the impact of external stress on lithium-ion battery are important in vehicle *** this work,18 Ah high power commercial cell with Li Ni_(0.5)Co_(0.2)Mn_(0.3)O_(2)/graphite electrode were adopted.A commercial compress machine was applied to monitor the mechanical characteristics under different stage of charge(SOC),lifetime and initial external *** dynamic and steady force was obtained and the results show that the dynamic force increases as the SOC increasing,*** the lifetime with high power driving mode,different external force is shown to have a great impact on the long-term cell performance,with higher stresses result in higher capacity decay rates and faster impedance increases.A proper initial external force(900 N)provides lower impedance *** analysis of the cells with2000 N initial force suggests a close correlation between electrochemistry and mechanics in which higher initial force leads to higher direct current internal resistance(DCIR)increase *** addition,for the cell with higher external force,deformation of the cathode and thicker solid electrolyte interface(SEI)film on the surface of anode and separator are *** reduction and closure was also verified after cycles which is an obstacle to the lithium ion *** largest cause of the observed capacity decline was the loss of active lithium through autopsy *** addition,for the cell with higher external force,deformation of the cathode and thicker SEI film on the surface of anode and separator are *** reduction and closure was also verified after cycles which is an obstacle to the lithium ion *** largest cause of the observed capacity decline was the loss of active lithium through autopsy analysis.

The transmission electron microscopy has been used to investigate the fine structure variation of 18R martensite under deformation in a polycrvstalline CuZnAl shape memory *** has been found that the strain is gabined by the reorientation of martensite variants in the ini- tial deformation *** addition to the result of optical microscopy studies,however,the reorientation is often incomplete and the interfaces among the prior variants still remain.A lot of twins will appear in martensite under enormous deformation,and the twin plane is(001) phane of martensite *** dislocations has also been observed in some *** this case,the martensite will lose its thermoelasticitv and the shape memory effect will be damaged.
