“…9 While these earlier findings demonstrated the prospective functionality of nanoscale polymers for 3D all-solid-state battery architectures, polymer formation via electro-oxidation may not always be desirable, particularly when the underlying architecture on which the polymer is deposited is designed to serve as the negative electrode. 17 Prieto and co-workers electrodeposited polyethyleneoxide-based films through the electroreduction of a diazonium group; the resulting films were grafted to the electrode surface and displayed electronic conductivity of 10 À10 S cm À1 , but the o10 nm thickness will limit the operating voltage when functioning as a solid-state electrolyte. Electropolymerization from acrylate-type monomers en route to solid-state electrolyte coatings was reported by Owen and co-workers; they deposited micrometres-thick polyacrylonitrile coatings on nickel foam and vitreous carbon followed by incorporation of electrolyte salts into the film to achieve ionic conduction.…”

Routes to 3D conformal solid-state dielectric polymers: electrodeposition versus initiated chemical vapor deposition

We show that two distinct methods, electropolymerization and initiated chemical vapour deposition (iCVD), can be adapted to generate ultrathin polymers (30-50 nm thick) at three dimensionally (3D) porous conductive substrates comprising B300 lm-thick carboncoated silica fiber paper (C@SiO 2 ). We selected 1,3,5-trivinyl-1,3,5trimethylcyclotrisiloxane (''V3D3'') as a common monomer amenable to polymerization by either approach. Electroanalytical and electrical measurements confirm that all carbon surfaces are passivated with electronically insulating poly(V3D3) coatings.The Achilles heel that trips up all-solid-state 3D energy-storage devices resides in the inability to form ultrathin dielectrics with high fidelity when conformally coating non-line-of-sight substrates such as ultraporous scaffolds and architectures. Of the limited fabrication protocols available to paint polymers throughout macroscopically thick structures while ''blind,'' electrodeposition and initiated chemical vapour deposition are the most compelling. Both methods offer conditions under which growth can be limited thus ensuring that monomer can access all of the internal surfaces. The critical chemical, physical, and electrical properties of nanoscale polymers generated by such methods-well-studied on planar substrates-must also be validated for the polymers when expressed in 3D. These data are necessary to demonstrate performance as a solid-state dielectric in 3D batteries and capacitors.

“…Due to computational limitations, only the single reference concentration of Li:O = 1:23, which approximately corresponds to that used in the experimental reference material, was used for the largest film thickness (380 Å). The bulk structures were doped with LiPF 6 at concentrations of Li:O = 1:21/1:42/1:63/1:84.…”

“…Multifunctional applications also pose additional challenges due to different and possibly conflicting requirements for optimum performance with respect to both functionalities. To address these issues, this contribution investigates the dependence on salt concentration of the mechanical properties of an interface between a graphitic carbon (GC)‐based electrode and a poly (propylene glycol) acrylate (PPGDA)‐based solid polymer electrolyte (SPE). In structural terms, the interface represents a fiber/SPE‐coating interface if a negative electrode is considered …”

This reactive molecular dynamics study explores the salt concentration dependence of the viscoelastic and mechanical failure properties of a poly(propylene glycol)/LiPF6‐based solid polymer electrolyte (SPE) at a graphitic carbon electrode interface. To account for the finite‐size effect of interface‐confined SPE films, the properties of two distinct film thicknesses are compared with the respective bulk properties. Additionally, the effect of uniaxial compression in the interface‐normal direction on free energy profiles of Li‐ion SPE‐desolvation is studied. © 2018 The Authors.

Electrodeposition induces material syntheses on conductive surfaces, distinguishing it from the widely used solid‐state technologies in Li‐based batteries. Electrodeposition drives uphill reactions by applying electric energy instead of heating. These features may enable electrodeposition to meet some needs for battery fabrication that conventional technologies can rarely achieve. The latest progress of electrodeposition technologies in Li‐based batteries is summarized. Each component of Li‐based batteries can be electrodeposited or synthesized with multiple methods. The advantages of electrodeposition are the main focus, and they are discussed in comparison with traditional technologies with the expectation to inspire innovations to build better Li‐based batteries. Electrodeposition coats conformal films on surfaces and can control the film thickness, providing an effective approach to enhancing battery performance. Engineering interfaces by electrodeposition can stabilize the solid electrolyte interphase (SEI) and strengthen the adhesion of active materials to substrates, thereby prolonging the battery longevity. Lastly, a perspective of future studies on electrodepositing batteries is provided. The significant merits of electrodeposition should greatly advance the development of Li‐based batteries.
