Dispersion of Amorphous Sn_2P_2O_7 in a Conductive Matrix as an Anode Material in Lithium Secondary Batteries

摘要

Tin-based materials may offer alternatives to anode materials in lithium secondary batteries, because of their higher gravimetric/volumetric capacity compared to graphite, a widely used anode. However, metal tin and tin oxides normally suffer substantial loss of capacity due to mechanical degradation during cycling. Dispersion of tin in a non-active or less active matrix was suggested to alleviate the capacity fading.
