Abstract
- Li4Ti5O12 is a promising anode for lithium‐ion batteries due to its zero‐strain properties. However, its low conductivity has greatly affected its rate performance. At the same time, the electrolyte decomposition during cycling also needs to be solved, especially at low cut‐off voltage. Herein, using a high‐throughput two‐step method, we synthesized Zr‐doped LTO modified by mesoporous LiBaF3 nanoparticles for alkali‐ion storage. The doping of Zr can enhance the electronic conductivity and facilitate the rate performance. Meanwhile, the coating of mesoporous LiBaF3 nanoparticles can form a mesoporous surface with large pore size (ca. 3–10 nm), which can benefit the alkali ion diffusion and simultaneously restrain the formation of an excess solid electrolyte interface to a reasonable range. The optimized material is used as an advanced anode for both lithium‐ion and potassium‐ion batteries, and good battery behavior including high‐rate performance and high stability is achieved.
