To address the poor electronic conductivity and easily dissolved in electrolyte of polyoxometalates (POMs), and considering the high electrical conductivity and configuration advantages of crumpled graphene balls (CGBs), herein, a series of POM‐based coordination polymers [Cu(pyttz)2]PMo12@CGB (n, n=1, 2, 3) were successfully synthesized, and electrochemical lithium storage performance and lithium ion diffusion kinetics were comprehensively investigated. Galvanostatic intermittent titration technique (GITT) and electrochemical impedance spectroscopy (EIS) study confirm that [Cu(pyttz)2]PMo12@CGB (n, n=1, 2, 3) integrates the advantage of high electronic conductivity of CGB and excellent Li+ migration kinetics of POMs, which greatly ameliorates the electrochemical performances of POMs, among [Cu(pyttz)2]PMo12@CGB (2) exhibits an excellent reversible specific capacity of around 941.4 mA h g−1 at 0.1 A g−1 after 150 cycles and admirable rate performance. This work will promote the development of POMCP anodes, thus fulfilling their potential in high‐performance LIBs.

Solid state physics is the basis of quantum mechanics to study the microstructure and macro properties of crystal materials. The combination of the two can promote the further improvement and development of the structure and properties of solid materials. Under the background of computer application, the development of quantum mechanics is inseparable from the effective support of solid-state physics. It can be seen that the relationship between solid-state physics and quantum mechanics is mutual promotion and correlation. Based on this, this paper first studies the key points of quantum mechanics and its relationship with solid state physics, and then analyses the concrete relationship between quantum mechanics and solid state physics based on computer.
