Crystallographic Insight of Reduced Lattice Volume Expansion in Mesoporous Cu2+‐Doped TiNb2O7 Microspheres during Li+ Insertion

TiNb2O7 represents a promising anode material for lithium‐ion batteries (LIBs), but its practical applications are currently hampered by the non‐negligible volumetric expansion and contraction during the charge/discharge process and the sluggish ion/electron kinetics. A combination technique is repo...
