“…[ 48 ] The strong absorption at 1690 cm -1 is ascribed to the carboxylate anion. [ 50,51 ] Considering the changes in the FT-IR peaks, we inferred that a cross-linked network consisting of PD-treated Super-P and PAA was well formed by the cross-linking reaction.…”

Zn, Cd, Hg, etc.), the so-called "lithium alloys." Li alloys, which have a larger number of Li ions per formula unit than graphite, consequently provide higher specifi c capacities than graphite. [ 11 ] For instance, fully lithiated Si (Li 22 Si 5 or Li 4.4 Si) has a theoretical specifi c capacity of 4200 mAh g -1 , the highest among the abovementioned alloying elements. [ 12,13 ] Consequently, Si is considered a promising anode material and, for decades, it has attracted intense research attention. However, the huge volume changes that occur during lithiation and delithiation result in cracking and crumbling ("pulverization") of the active material. [ 5,11 ] This consumes a large amount of available Li ions and electrolytes and forms a passivation fi lm, the so-called solid electrolyte interphase (SEI), [ 14,15 ] on the Si surface exposed to the electrolyte. In addition, loss of electronic interparticle contact occurs. [ 4,16 ] Consequently, these factors eventually lead to capacity fading, and, as a result, the implementation of Sibased anodes in LIBs has not been realized.Generally, the electrodes for LIBs consist of three major constituents: (1) the active materials, (2) polymeric binders, and (3) conductive additives. First, the development and modification of Si active materials have been intensively studied. To release dimensional stress in Si-based active materials during lithiation and delithiation, many nanostructures, including 0D nanoparticles, 1D nanowires and nanotubes, 2D nanosheets and nanofl akes, and core-shell structured nanomaterials, have been explored. [ 17,18 ] These materials reduce mechanical stress because fracture does not occur in Si nanostructures below a critical size. [ 19 ] However, nanostructured materials still suffer from several severe shortcomings; for example, an increased surface area, leading to a larger SEI and consumption of lithium ions, low tap densities, aggregation, and safety problems associated with the fl ammable and explosive tendencies of metallic nanopowders. [ 20,21 ] Therefore, as the next step, nano/microhierarchical structures, in which nanosized Si particles are embedded in a microscale framework, e.g., conductive carbon-based materials, have attracted much interest. [ 17,22,23 ] However, owing to the complex structure of these materials, these approaches generally have high production costs and are not appropriate for mass production. For the successful implementation of Si-based anodes in LIBs, low cost, and scalability are prerequisites.Second, it has been recently verifi ed that the appropriate choice of polymeric binders for Si-based anodes can improveThe study has developed a facile polydopamine (PD) surface coating method for a typical conductive additive, Super-P. This method is effi cient, economical, and environmentally friendly, and it can be used for the mass production of Super-P. PD treatment converts the hydrophobic surfaces of Super-P into hydrophilic surfaces, facilitating slurry preparation, and slurry coating for the fabrication of Si-ba...

“…The first endothermic peak was observed at 40 C, while the second one was observed at 148 C (Figure 1e). A broad crystallization T c peak was also evident between 40 C and 80 C. This broad crystallization peak was most certainly a result of conformational changes in the PAA macromolecules 40 . The presence of the hydrophilic pendent COOH À groups on the PAA polyelectrolyte macromolecules favors its suitability as an adhesive and coating agent since sufficient hydrophilic COOH À groups for replacing polar OH À groups at the substrate site is a pre-requisite.…”

“…metal and polyimide, and then cured at high temperature. If a polyimide precursor is coated directly onto copper, either adhesion of polyimide to copper is weak or the poly(amic acid) reacts with copper [4,5], leaving copper oxide particles in the cured polyimide layer, which results in an increase of the dielectric constant and degradation of the material properties. Kim et al [6,7] reported that pyromellitic dianhydrideoxydianiline (PMDA-ODA) poly(amic acid) in a solvent reacted with copper during a high-temperature 300°C) curing process to form copper oxide particles which diffused into the bulk of PMDA-ODA polyimide.…”
