To obtain high-energy density Li-ion batteries for the next-generation storage devices, silicon anodes provide a viable option because of their high theoretical capacity, low operating potential versus lithium (Li), and environmental abundance. However, the silicon electrode suffers from large volume expansion (∼300%) that leads to mechanical failure, cracks in the SEI (solid electrolyte interphase), and loss of contact with the current collector, all of which severely impede the capacity retention. In this respect, the choice of binders, carbon, electrolyte, and the morphology of the silicon itself plays a critical role in improving capacity retention. Of specific mention is the role of binders where a carboxylic acid-heavy group, PAA (polyacrylic acid), has been demonstrated to have better cycling capacity retention as compared to CMC (carboxy methyl cellulose). Traditionally, the role of binders has been proposed as a soft matrix backbone that allows volume expansion of the anode while preserving its m...
