Developing synthetic methods for graphene based cathode materials, with low cost and in an environmentally friendly way, is necessary for industrial production.
To increase the specific capacity and conductivity of lithium titanate, low-cost and environmentally friendly carbon quantum dots (CQDs) were used to composite with Al3+ and Mn4+ co-doped Li4Ti5O12 (LTO-Al/Mn) to improve its electrical properties.
Due to their low cost and improved safety compared to lithium-ion batteries, sodium-ion batteries have attracted worldwide attention in recent decades.
