摘要：

We report the high capacity and rate capability of mesoporous CO3O4 nanowire (NW) arrays as anodes in Li ion batteries. At a current of 1C, the NW arrays maintain a capacity of 700 mAh/g after 20 discharge/charge cycles. When the current is increased to 50C, 50% of the capacity can be retained. With their ease of large area synthesis and superior electrochemical properties, these CO3O4 NW arrays will be interesting for practical Li ion batteries.
