Study on the performance of LiCoxMn2-xO4-yFy using spent alkaline Zn-Mn batteries as manganese source
We have successfully synthesized the spinel LiCoxMn2-xO4-yFy cathode materials by simple sol-gel method using the manganese source that is recovered from spent alkaline Zn-Mn batteries through hydrometallurgy recycling technology. The charge-discharge curves demonstrate that the LiCo0.1Mn1.9O4 exhibited good cycling performance with 94.0% capacity retention after 100 cycles. The LiMn2O3.9F0.1 possesses the maximum initial discharge capacity of 124.54 mAh . g(-1). The LiCo0.1Mn1.9O3.9F0.1 has the best comprehensive performance. The initial discharge capacity of LiCo0.1Mn1.9O3.9F0.1 is 120.7 mAh . g(-1), the capacity retention is 91.7% after 100 cycles. (C) 2014 Elsevier B.V. All rights reserved.
