Abstract: | The influence of vinylene carbonate addition to aqueous LiNO3 solution on the Li-ion insertion performance of a Li1.05Cr0.10Mn1.85O4 was studied by galvanostatic charging/discharging. Without additive, the coulombic capacity amounted initially to 80 mA h g?1 and, during 50 galvanostatic charging/discharging cycles, decreased to 44.1% of the initial value. Upon VC addition in an amount of 1 wt.%, the initial discharge capacity of 112 mA h g?1 was registered which after 100th charging/discharging cycles retained even 82% of the initial value. This is the first report of a successful use of an additive to improve the behaviour of a Li-intercalation material in an aqueous solution. |
