| Abstract: | LiMn2O4 was synthesized rapidly by microwave heating. The product phases of the microwave synthesis and conventional solid-state synthesis were comparatively invesitigated. The capacity of microwave synthesis product decreases relatively slow. The lithium ion can be inserted into and extracted from the spinel framework structure fluently after cycling. But the capacity of the conventional solid-state synthesis product is more remarkably lowered. The spinel framework structure was destroyed which hindered the lithium ion from inserting and extracting. The influential factors of the process parameters are discussed such as heat preservation time, pre-heating at 400°C for 24h and coupled agent. HAO Hua: Born in 1971.
