%X Novel ultrathin Li2MnSiO4 nanosheets
have
been prepared in a rapid one pot supercritical fluid synthesis method.
Nanosheets structured cathode material exhibits a discharge capacity
of ∼340 mAh/g at 45 ± 5 °C. This result shows two
lithium extraction/insertion performances with good cycle ability
without any structural instability up to 20 cycles. The two-dimensional
nanosheets structure enables us to overcome structural instability
problem in the lithium metal silicate based cathode materials and
allows successful insertion/extraction of two complete lithium ions.
