In-situ Synthesis of In2O3 (Bi2O3)/Sisal Fiber-Based Carbon Composites by Carbon Heating and Its Application in Lead Carbon Batteries

摘要:

利用炭原位合成制备了Bi2O3、In2O3两种不同的析氢抑制剂/剑麻纤维基碳复合材料，利用XRD, SEM，EDS、N2吸附-脱附曲线等方法对碳复合材料进行表征。SEM和XRD结果表明复合材料均结晶程度较好，剑麻纤维基碳材料表面可以观测到大量嵌入到纤维内部的析氢抑制剂微粒，且分布均匀。将制备的碳复合材料与电池辅剂进行混合，制备出铅碳电池负极材料，电化学测试结果表明In2O3/剑麻纤维基碳复合材料的负极材料具有更长的循环寿命以及更好的电化学性能，其最终容量可达到102.25 mAh/g，循环150圈后比容量占最初比容量的79.8%。

Abstract:

Two different hydrogen evolution inhibitor Bi2O3 and In2O3/sisal fiber-based carbon composites were prepared by in-situ synthesis of carbon. The carbon composites were characterized by XRD, SEM, EDS and N2 adsorption-desorption curves. The results of SEM and XRD indicate that the composites have a good degree of crystallization. A large amount of hydrogen evolution inhibitor particles embedded in the fiber surface can be observed on the surface of the sisal fiber-based carbon material, and the distribution is uniform. The prepared carbon composite material was mixed with a battery auxiliary agent to prepare a lead carbon battery anode material. The electrochemical test results show that the anode material of the In2O3/sisal fiber-based carbon composite material has a longer cycle life and better electrochemistry. Performance, the final capacity can reach 102.25 mAh / g, after 150 cycles, the specific capacity accounts for 79.8% of the initial specific capacity.
