Abstract

The performance of TiNb₂O₇ (TNO) is enhanced for fast-charging lithium-ion batteries by coating with graphdiyne (GDY). This modification improves the conductivity, rate capability, and cycling stability of TNO. The GDY coated TNO (TNO@GDY) retains 73% capacity after 1000 cycles at 5C, demonstrating its potential for advanced energy storage applications.
