We report a simple strategy to synthesize high tap density Li₄Ti₅O₁₂ particles with excellent electrochemical performance, whose tap density could be controlled by the starting materials. A series of high tap density Li₄Ti₅O₁₂ particles are successfully synthesized with high tap density TiO₂ through hydrothermal process with a short post‐annealing. The electrochemistry performances of them were carefully researched in this work. The high tap density Li₄Ti₅O₁₂ showed similar performance with normal Li₄Ti₅O₁₂ particles. The highest tap density of Li₄Ti₅O₁₂ particles is 1.4 g⋅cm⁻³, whose capacity is 134 mAh⋅g⁻¹ at 10 C. Those high tap density Li₄Ti₅O₁₂ display their promising commercial application in high‐energy density lithium ion batteries.
