This work demonstrates a high-performance and durable silicon nanoparticle-based negative electrode in which conventional polymer binder carbon black additive are replaced with lignin. The mixture of nanoparticles lignin, low cost, renewable, widely available biopolymer, was coated on copper substrate using the slurry mixing coating method subsequently heat-treated to form composite electrode. showed excellent electrochemical performance an initial discharge capacity up 3086 mAh g–1...

Because of its natural abundance and high theoretical specific capacity (3579 mAh g-1, based on Li15Si4), silicon composites have been extensively studied as the negative electrode for future energy density lithium-ion batteries. While rapid failure due to significant volumetric strain lithium-silicon reactions makes bulk unsuitable practical applications, nanoparticles can sustain large volume changes without fracturing. However, polymeric binders are usually required maintain structural...
