中文摘要	li(mn1/3ni1/3co1/3)o-2 cathode materials were fabricated by a hydroxide precursor method. al2o3 was coated on the surface of the li(mn1/3ni1/3co1/3)o-2 through a simple and effective one-step electrostatic self-assembly method. in the coating process, a nahco3-h2co3 buffer was formed spontaneously when co2 was introduced into the naalo2 solution. compared with bare li(mn1/3ni1/3co1/3)o-2, the surface-modified samples exhibited better cycling performance, rate capability and rate capability retention. the al2o3-coated li(mn1/3ni1/3co1/3)o-2 electrodes delivered a discharge capacity of about 115 mah.g(-1) at 2 a.g(-1), but only 84 mah.g(-1) for the bare one. the capacity retention of the al2o3-coated li(mn1/3ni1/3co1/3)o-2 was 90.7% after 50 cycles, about 30% higher than that of the pristine one.
