摘要：

Silicon suboxides (SiOx) have been widely concerned as a practical anode material for the next-generation lithium-ion batteries due to their relatively high theoretical capacity and lower volume change compared to silicon (Si). Nevertheless, traditional binder poly(vinylidene difluoride) (PVDF) still cannot hold the integrity of the SiOx particle due to its weak van der Waals force. Herein, a copolymer binder for SiOx microparticles is synthesized through a facile method of free radical polymerization between acrylamide (AM) and acrylic acid (A...
