Abstract

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 110 mAh/g at 4.5 C and 95 mAh/g even at 91 C in 0.5 mol/l Li₂SO₄ aqueous electrolyte. When charged at 136 C, 84% capacity could be obtained. In addition, its cycling behavior is also very good. After 200 cycles at 4.5 C, there is no evident capacity fading.
