Recently, MAB phases (layered ternary borides) have attracted much interest for their mechanical, oxidation resistant and functional properties. Following the MXene route, they have also been
predicted as candidates for novel 2D borides (MBenes) synthesis. Furthermore, MBenes have been theoretically predicted to have excellent performance for Li-ion batteries. Herein, we have investigated the synthesis of the Ni(n+1)ZnBn (n = 1, 2) MAB phases and studied their potential for Li-ion batteries. Interestingly, exposing these materials to acid, caused opening between the layers and create some pores in the bulk samples without chemical etching. Analyzing the acid-treated Ni2ZnB and Ni3ZnB2 showed specific capacities of 90 mAh g-1 and 80 mAh g-1, respectively. These results show that MAB phases containing pores or opened sheets are active materials for Li-ion battery applications. This work not only confirms the theoretical predictions but also it hints at an exciting future for MBenes as excellent battery materials. |
