      abstract     = {Massive volume change during (de-)lithiation and subsequent
                      challenges, such as pulverization of active materials,
                      delamination of electrode from the current collector, and
                      fragile solid electrolyte interphase, are among the main
                      impediments hindering the large-scale commercialization of
                      silicon-containing anode materials in lithium-ion batteries.
                      In this regard, designer polymeric binders with unique
                      chemistries are considered as enabling solutions. Polymeric
                      materials endowed with functional groups such as –OH,
                      –COOH/COO−, and –NH2/NH3+, capable of building strong
                      H bonds, are hailed as effective binders for Si-containing
                      anode materials. Herein, chitosan biopolymers are
                      investigated as a green and environmentally friendly binder
                      in a silicon/graphite (Si/Gr) anode and compared to lithium
                      poly(acrylic acid)/sodium carboxymethyl cellulose binders.
                      The effect of degree of acetylation (DA) and degree of
                      polymerization of chitosan on the electrochemical
                      performance of Si/Gr anode-based cells is investigated.
                      Anodes with chitosan binder with DA of $50\%$ show the most
                      promising electrochemical performance in Si/Gr||lithium
                      metal and lithium nickel manganese cobalt oxide
                      (NMC622)||Si/Gr cells. Crosslinking of chitosan binder with
                      citric acid monohydrate in combination with free-standing
                      electrodes results in improved electrochemical performance
                      in full cells. The surface chemistry of electrochemically
                      cycled Si/Gr anodes with/without chitosan binder is
                      investigated by X-ray photoelectron spectroscopy.},
