论文摘要
四种不同形式的碳：人毛的活性炭（AC），来自大麻纤维的AC，富勒烯提取物，由C $ _ {60} $和C $ _ {70} $ fullerene（CFEX）和Super-P Carbon Black组成，并被测试，并作为非含水铝铝的载体测试和比较。这些材料在其一般结构，孔隙率和形态上有所不同。富勒烯显示出结晶的结构，而大麻纤维，超级P和头发本质上是无定形的。在所有材料中，从头发获得的AC在50个周期后以103 mAh g $^{ - 1} $记录的最高特异性容量，库仑效率为$ \ sim $ 90％，目前为50 mA g $^{ - 1} $。大麻纤维和Super-P分别以56 mAh g $^{ - 1} $和84 mAh g $^{ - 1} $达到了最高的特定能力。 CFEX以78 mAh g $^{ - 1} $记录了其最高容量，并维持了50个周期。将细胞充电并分别排放到2.45 V和0.2 V。
Four different forms of carbon: activated carbon (AC) from human hair, AC from hemp fibers, a carbon fullerene extract consisting of C$_{60}$ and C$_{70}$ fullerene (CFEx) and Super-P carbon black were tested and compared as cathodes for non-aqueous aluminium-ion batteries (AIBs). These materials differ in their general structure, porosity and morphology. Fullerenes display a crystalline structure, whereas hemp fibers, Super-P and hair are amorphous in nature. Of all materials, AC obtained from hair recorded the highest specific capacity after 50 cycles at 103 mAh g$^{-1}$ with a Coulombic efficiency of $\sim$90% at a current rate of 50 mA g$^{-1}$. Both hemp fibers and Super-P achieved their highest specific capacities at 56 mAh g$^{-1}$ and 84 mAh g$^{-1}$ respectively. CFEx recorded its highest capacity at 78 mAh g$^{-1}$ and maintained it for 50 cycles. The cells were charged and discharged to 2.45 V and 0.2 V respectively.
