Low-cost and environmentally friendly synthesis of an Al(3+) and Mn(4+) co-doped Li(4)Ti(5)O(12) composite with carbon quantum dots as an anode for lithium-ion batteries

To increase the specific capacity and conductivity of lithium titanate (LTO), low-cost and environmentally friendly carbon quantum dots (CQDs) were used to composite with Al(3+) and Mn(4+) co-doped Li(4)Ti(5)O(12) (LTO-Al/Mn) to improve its electrical properties. The Al(3+) and Mn(4+) were successfu...

description To increase the specific capacity and conductivity of lithium titanate (LTO), low-cost and environmentally friendly carbon quantum dots (CQDs) were used to composite with Al(3+) and Mn(4+) co-doped Li(4)Ti(5)O(12) (LTO-Al/Mn) to improve its electrical properties. The Al(3+) and Mn(4+) were successfully substituted for Ti located at (16d) sites in the LTO and the CQDs formed a composite with LTO-Al/Mn. The specific capacity of the first cycle at 0.1C increased to 296.5 mA h g(−1), and the impedance decreased to 16.8 Ω. The specific capacity maintained 236.0 mA h g(−1) after 100 cycles.
