Pristine LNCM and LNCMA as Li-rich cathode materials for lithium ion batteries were synthesized via a sol–gel route. The Al-substituted LNCM sample exhibits an enhanced high rate performance and superior cyclability.
A composite of SnO2and three-dimensional graphene (SnO2/3DG) was fabricated using a hydrothermal method, with polystyrene balls (PS) as templates, and was found to have excellent electrochemical performance..
