Abstract
Si/SiO_x composite anodes were prepared using a facile solution reaction-based method. Their initial capacity was significantly improved to 1.3 times that of SiO_x by incorporating 3 wt% silicon nanoparticles into the SiO_x. The capacity retention of the Si/SiO_x anodes after 50 charge-discharge cycles was significantly enhanced, to 99%, compared with..... More
