TiO2-(B) nanotubes show improved performances in Li-ion cells compared with lithium titanate spinels, but suffer from large irreversible capacity loss on the first charge/discharge cycle. By decoupling bulk (intercalation) and surface reactions of nanotube electrodes Li cells, major cause is identified its mitigation demonstrated by using chemical pretreatments.
