“…During p-doping, some of the delocalized electrons are removed, and positive polarons/bipolarons are generated. 87 The electrons within the resultant partially empty energy level have high mobility. In the case of n-doped polymers, electrons are injected to the polymer backbone, thus generating negative polarons/bipolarons with high mobility.…”

The emerging era of supramolecular polymeric binders in silicon anodes

Silicon (Si) anode is among the most promising candidates for the next-generation high-capacity electrodes in Li-ion batteries owing to its unparalleled theoretical capacity (4200 mA h g À1 for Li 4.4 Si) that is approximately 10 times higher than that of commercialized graphitic anodes (372 mA h g À1 for LiC 6 ).The battery community has witnessed substantial advances in research on new polymeric binders for silicon anodes mainly due to the shortcomings of conventional binders such as polyvinylidene difluoride (PVDF) to address problems caused by the massive volume change of Si (300%) upon (de)lithiation. Unlike conventional battery electrodes, polymeric binders have been shown to play an active role in silicon anodes to alleviate various capacity decay pathways. While the initial focus in binder research was primarily to maintain the electrode morphology, it has been recently shown that polymeric binders can in fact help to stabilize cracked Si microparticles along with the solid-electrolyte-interphase (SEI) layer, thus substantially improving the electrochemical performance. In this review article, we aim to provide an in-depth analysis and molecular-level design principles of polymeric binders for silicon anodes in terms of their chemical structure, superstructure, and supramolecular interactions to achieve good electrochemical performance. We further highlight that supramolecular chemistry offers practical tools to address challenging problems associated with emerging electrode materials in rechargeable batteries.

Nanostructured composites of lead oxide/copper-carbon (PbO/Cu-C) were synthesized through in situ solvothermal synthesis and heat treatment of PbO/Cu with polyvinyl pyrrolidone (PVP) and used as lithium-ion battery anodes. A PbO active particle was embedded in the Cu and PVP-C matrix, accommodating volume changes and maintaining the electronic conductivity of PbO. The composite exhibits a superior electrochemical performance, with a capacity of 420 mA h g À1 at a current density of 165 mA g À1 , compared with previously reported Pb and PbO composite anodes. The developed anode exhibits >90% capacity retention after 9500 cycles, beginning from the second cycle, at a current density of 5.5 A g À1 .
