Abstract: Methods for fabricating electrodes include coating a current collector with a slurry to form a coated current collector. The slurry includes a dry fraction, including silicon particles, polymeric binders, and one or more types of naturally occurring carbonaceous filaments, and one or more solvents. The coated current collector is heat treated to produce the electrode having a layer of silicon-based host material. The one or more naturally occurring carbonaceous filaments can include animal fibers, chitin, alginate, cellulose, keratin, and chitosan, and can have an average length of 1 μm to 50 μm and an average diameter of 1 nm to 500 nm. The dry fraction can include 5 wt. % to 95 wt. % silicon particles, 0.1 wt. % to 15 wt. % polymeric binders, and 1 wt. % to 20 wt. % naturally occurring carbonaceous filaments. The method can include assembling a battery cell by disposing the electrode and a positive electrode in electrolyte.

Abstract: A lithium-ion conducting, solid electrolyte is deposited on a thin, flexible, porous alumina membrane which is placed between co-extensive facing side surfaces of a porous, lithium-accepting, negative electrode and a positive electrode formed of a porous layer of particles of a compound of lithium, a transition metal element, and optionally, another metal element. A liquid electrolyte formed, for example, of LiPF6 dissolved in an organic solvent, infiltrates the electrode materials of the two porous electrodes for transport of lithium ions during cell operation. But the solid electrolyte permits the passage of only lithium ions, and the negative electrode is protected from damage by transition metal ions or other chemical species produced in the positive electrode of the lithium-ion cell.
