چکیده انگلیسی
Nanochain LiMn2O4 was prepared by a starch-assisted sol-gel method. Its electrochemical behavior as a cathode material for aqueous rechargeable lithium batteries (ARLBs) was characterized by cyclic voltaammograph, capacity measurement and cycling test. Results show that the nanochain LiMn2O4 has an ultra-fast charge capability. It presents a reversible capacity of 110Â mAh/g at 4.5Â C and 95Â mAh/g even at 91Â C in 0.5Â mol/l Li2SO4 aqueous electrolyte. When charged at 136Â C, 84% capacity could be obtained. In addition, its cycling behavior is also very good. After 200Â cycles at 4.5Â C, there is no evident capacity fading.
