Developing high-energy-density and good cycling stability of lithium ion batteries is regarded as the core of next-generation rechargeable batteries. However, the considerable volume variation during the lithiation and delithiation process drives big challenges to its commercialization in lithium-ion batteries. In this study, silicon composite anodes with the three-dimensionally cross-linked binder (c-PAA-CMC) ; poly(acrylic acid) and sodium carboxymethyl cellulose, which possess mechanical resistance to strain, are fabricated and evaluated. Compared with the Silicon composite anodes with the polyvinylidene fluoride binder, three-dimensionally interconnected binder indicates a significantly enhanced reversible capacity and a high initial coulombic efficiency of 88.2%. The three-dimensionally cross-linked binders provide promising way to develop next generation Lithium ion battery with high-energy-density and good cycle performance. |
