Abstract EN
High capacity Li2MnSiO4/C nanocomposite with good rate performance was prepared via a facile sol-gel method using ascorbic acid as carbon source.
It had a uniform distribution on particle size of approximately 20 nm and a thin outlayer of carbon.
The galvanostatic charge-discharge measurement showed that the Li2MnSiO4/C electrode could deliver an initial discharge capacity of 257.1 mA h g−1 (corresponding to 1.56 Li+) at a current density of 10 mA g−1 at 30°C, while the Li2MnSiO4 electrode possessed a low capacity of 25.6 mA h g−1.
Structural amorphization resulting from excessive extraction of Li+ during the first charge was the main reason for the drastic capacity fading.
Controlling extraction of Li+ could inhibit the amorphization of Li2MnSiO4/C during the delithiation, contributing to a reversible structural change and good cycling performance.
