Lithium ion battery(LIB) have been gathered tremendous attention along to progress of portable electronic devices and needs to use eco-friendly energy. Among challenging views for versatile use of lithium ion battery, it is the most requirable point is to increase the amount of energy of LIB which is possible to be stored in LIB. In the aspect for solution of this challenge, SiOx has been considered as next-generational anode material due to high capacity and stability. Although SiOx has vast advantages for application to anode of LIB, SiOx also shows performance degradation phenomena owing to its poor electrical conductivity and reactivity of amorphous silica in SiOx. Herein, we analyzed microscopic structural changes of SiOx related to performance degradation at specific cycles, and suggest the structural degradation mechanisms of SiOx and the direction for preventing SiOx from structural performance degradation through analysis of component changes as cycles. |
