ChemElectroChem, Volume 13, Issue 9, 5 May 2026.This study shows that the beneficial effect of Nb by Ti partial substitution on TiO2 consists of a significant increase in the lithium diffusion coefficient, resulting from the opening of structural tunnels. This explains the intercalation pseudocapacitive behavior of Nb‐derivatives of TiO2. The electrochemical performance of a rutile with high niobium
