free-standing electrodes 的意思?原句是这样的“In addition to using high capacity active materials like silicon, free-standing electrodes have generated signi?cant interest due to their potential to eliminate electrochemical ... 就是类似的意思,文章写的基底是金属片。材料需要负载在金属基底上组成电极,金属基底仅起到收集电流的作用,所以属于没有活性的部分“inactive mass”。而free standing由于材料本身就是电极,不再需要额外的基底,当然可以减少原来基底所占的质量。查看更多
