Approaching high-performance lithium storage materials by constructing Li2ZnTi3O8@LiAlO2 composites

Li2ZnTi3O8anode: design from material to electrode and devices

“…Yi's group prepared Li 2 ZnTi 3 O 8 @LiAlO 2 (LZTAO) via a two-step solid-state route. 44 The LiAlO 2 modification was effective in improving the structure stability, transfer of Li + ions, and Li-storage capability of Li 2 ZnTi 3 O 8 @LiAlO 2 as compared with the pristine LZTO. 203.9, 194.8, 187.4, 180.6, and 175.6 mA h g −1 were delivered at 0.5, 1, 2, 3, and 5 C for Li 2 ZnTi 3 O 8 @LiAlO 2 with good rate capability, respectively.…”

“…Yi's group prepared Fe 2 O 3 -coated, Mo-doped, and LiAlO 2 -coated LZTO, respectively. 28,36,44 The ever-increasing trend of the specific capacities before 150–500 cycles for the three samples was attributed to the gradual activation process, including the optimization of lithiation-induced structure, reconfiguration of the SEI film, reduced particle size, and generation of organic polymeric/gel-like layer owing to the decomposition of the electrolyte at low potentials. Inamdar et al investigated the effects of operating temperature on the electrochemical performance of the LZTO electrode.…”
