A hammer-like Co3O4 was firstly prepared by using metal-organic framework-74 as a template, and then compounded with elemental Ag to fabricate a highly active catalyst with an improved electronic conductivity. The Li-O2 battery with this prepared catalyst has a specific discharge capacity of 13 945 mA·h/g at a current density of 100 mA/g. Even at a high current density of 1 000 mA/g, the battery can still maintain a specific discharge capacity of 4 476.3 mA·h/g, indicating that it has an excellent rate performance. Also, the cycle performance is greatly improved. For the limited specific capacity of 1 000 mA·h/g at the current density of 500 mA/g, the battery with Ag/Co3O4 catalyst can be used for 195 cycles, while that with Co3O4 catalyst can be used for only 42 cycles.

以金属有机框架-74为模板制备了仿锤体状Co3O4,然后与单质Ag复合,通过界面工程提高了材料电导率,制备出Li-O2电池的高活性催化剂Ag/Co3O4。在100 mA/g电流密度,使用Ag/Co3O4催化剂的Li-O2电池的放电比容量达到了13 945 mA·h/g,即使在1 000 mA/g高电流密度,依然可以保持4 476.3 mA·h/g的放电比容量,证明其具有出色的倍率性能。同时,循环性能也得到了大幅提高,在电流密度为500 mA/g,限制比容量为1 000 mA·h/g,使用Ag/Co3O4催化剂的电池可以稳定循环195圈,而使用Co3O4催化剂的电池只能循环42圈。

以金属有机框架-74为模板制备了仿锤体状Co3O4,然后与单质Ag复合,通过界面工程提高了材料电导率,制备出Li-O2电池的高活性催化剂Ag/Co3O4。在100 mA/g电流密度,使用Ag/Co3O4催化剂的Li-O2电池的放电比容量达到了13 945 mA·h/g,即使在1 000 mA/g高电流密度,依然可以保持4 476.3 mA·h/g的放电比容量,证明其具有出色的倍率性能。同时,循环性能也得到了大幅提高,在电流密度为500 mA/g,限制比容量为1 000 mA·h/g,使用Ag/Co3O4催化剂的电池可以稳定循环195圈,而使用Co3O4催化剂的电池只能循环42圈。

A hammer-like Co3O4 was firstly prepared by using metal-organic framework-74 as a template, and then compounded with elemental Ag to fabricate a highly active catalyst with an improved electronic conductivity. The Li-O2 battery with this prepared catalyst has a specific discharge capacity of 13 945 mA·h/g at a current density of 100 mA/g. Even at a high current density of 1 000 mA/g, the battery can still maintain a specific discharge capacity of 4 476.3 mA·h/g, indicating that it has an excellent rate performance. Also, the cycle performance is greatly improved. For the limited specific capacity of 1 000 mA·h/g at the current density of 500 mA/g, the battery with Ag/Co3O4 catalyst can be used for 195 cycles, while that with Co3O4 catalyst can be used for only 42 cycles.
