Summary: The limited capacity of graphite anodes in high-performance batteries has sparked interest in alternative materials. Titanium niobium oxide (TNO) shows great potential as a next-generation anode material due to its high capacity, but its electrochemical behavior is not yet well understood. This study reveals that the structural weakness of TNO affects its long-term cycling stability, with capacity fading caused by amorphization and increased impedance. Carbon doping in TNO effectively suppresses impedance increase, offering a possible remedy to the stability issue.
