英文摘要 | Boron, the most ideal lithium-ion battery anode material, demonstrates highest theoretical capacity up to 12 395 mA h g(-1) when forming Li5B. Furthermore, it also exhibits promising features such as light weight, considerable reserves, low cost, and nontoxicity. However, boron-based materials are not in the hotspot list because Li5B may only exist when B is in atomically isolated/dispersed form, while the aggregate material can barely be activated to store/release Li. At this time, an ingenious design is demonstrated to activate the inert B to a high specific capacity anode material by dispersing it in a Fe matrix. The above material can be obtained after an electrochemical activation of the precursors Fe2B/Fe and B2O3/Fe. The latter harvests the admirable capacity, ultrahigh tap density of 2.12 g cm(-3), excellent cycling stability of 3180 mA h cm(-3) at 0.1 A g(-1) (1500 mA h g(-1)) after 250 cycles, and superlative rate capability of 2650 mA h cm(-3) at 0.5 A g(-1), 2544 mA h cm(-3) at 1.0 A g(-1), and 1696 mA h cm(-3) at 2.0 A g(-1). Highly conductive matrix promoted reversible Li storage of boron-based materials might open a new gate for advanced anode materials. |
