摘要:1-丁基-1-甲基吡咯烷鎓双(氟磺酰基)酰胺 (Bmpfsa) 和 1-丁基-1-甲基吡咯烷鎓双(三氟甲基磺酰基)酰胺 (Bmptfsa) 在玻碳 (Gc) 电极上形成固体电解质界面 (Sei)利用二茂铁 (Fc) 的氧化还原反应研究了含有 Li +,Na +,K + 和 Ni 2+ 的物质.在碱金属离子存在的情况下,相对于 Bmpfsa 中的 Ag|ag(I),将电极保持在-1.4 至-1.5 V 后,Fc 氧化的阳极峰值电位 (E Pa ) 发生变化. Fsa-的分解通过 X 射线光电子能谱 (Xps) 在含有碱金属离子的 Bmpfsa 中在-1.5 V Vs Ag|ag(I) 下保持 6 小时的 Gc 电极上证实. E Pa 的变化也可能表明 Fsa-型离子液体中形成了均质 Sei.此外,在 50 Mm Ni(Tfsa) 2 /bmptfsa 中,将电极保持在比-0

摘要:A silicon graphene-incorporated rechargeable Li-ion battery with enhanced energy delivery and cycling life comprising a high-performance Si/graphene composite anode, a cathode film and electrolyte is disclosed. The anode and cathode are immersed in or partially immersed in the electrolyte; wherein the anode is formed of a mixture of carbon coated Si and graphene composite with a polymer binder and a conductive additive. A method for fabricating such Si and graphene-based anode comprises the steps synthesis of carbon coated Si particles by polymer encapsulation and carbonization; enveloping the coated Si particles in graphene by mechanical agitation; formulating the carbon coated Si and graphene with a polymer binder and conductive additive; depositing the mixture onto current collectors. The anode structure affords a combination of superior rate capability, cycling life and improved volumetric capacity.
