摘要

Co-B alloy with mesoporous structure was firstly synthesized using room-temperature ionic liquids as templates and investigated as an anode for secondary alkaline batteries. Investigations indicate that such mesoporous structure facilitated the electrochemical hydrogen storage. It maintained 94% of the initial capacity (336 mA h/g) after 50 cycles. The excellent cycling performance is most likely due to the stable structure during cycling. Meanwhile, it exhibited an excellent rate capability. The results demonstrated that the prepared Co-B-mesoporous is capable of serving as a high power capability anode for the rechargeable alkaline batteries.
