摘要 研究了GNSs(石墨烯)、Super P炭黑、VGCF(气相沉积碳纤维)等三种具有不同形貌的碳基材料对锂空气电池放电容量的影响,并以Super P炭黑为碳基材料,分别考察了碳负载量和粘结剂含量对锂空气电池放电性能的影响。为了进一步研究限制锂空气电池放电性能的因素,采用水热法合成了具有高比表面积的空心刺球状α-MnO2,制备了SuperP/α-MnO2/PVDF复合空气电极,考察了锂空气电池放电过程中的速率控制步骤。 The influence of three kinds of carbon with different morphologies such as GNSs,Super P and VGCF on the discharge performance of lithium-air batteries was studied.And then Super P was selected as carbon substrate material and the effect of carbon loading and binder content on the discharge performance of lithium-air batteries was investigated.In order to study the factor that restrict the discharge performance of lithium-air batteries,hollow structured α-MnO2 microspheres were synthesized using a hydrothermal method and Super P/α-MnO2/PVDF composite air electrode was prepared to study the rate controlling step of lithium-air batteries in discharging process.
