摘要：
A cathode material Na0.42Mn0.96Ti0.04O2 with conjugated layered and tunnel structures was synthesized via a convenient solid-state method. The designed conjugated structure enables superior electrochemical properties such as 93.9% capacity retention after 200 cycles at 1 C and excellent rate capability with a reversible capacity of 83.9 mAh g(-1 )at 20 C.
