Until recently, the memory effect was believed to be absent in Li‐ion battery materials. Here, the memory effect is clearly observed in anatase TiO 2 nanoparticles when they are used as the negative electrode material in Li‐ion batteries. Additionally, the memory effect strongly decreases with increasing specific surface area of the TiO 2 sample.
