The present teachings described a bias charging member and a method of manufacturing a charging member. The bias charging member includes a conductive core and an outer surface layer disposed on the conductive core. The outer surface layer includes a polycarbamate resin and a polyaldehyde cross-linker.

Provided is a polymer having a sharp melting peak and allowing easy adjustment of the melting peak temperature. Specifically provided is a polymer having two or more kinds of constitutional units containing an alkyl group having 14 or more and 30 or less carbon atoms, wherein the proportions of the number of the two or more kinds of constitutional units containing an alkyl group having 14 or more and 30 or less carbon atoms are each 20% or more, with respect to 100% of the total number of all constitutional units containing an alkyl group having 14 or more and 30 or less carbon atoms. An enthalpy of fusion of the polymer observed within a temperature range of 10 C. or higher and lower than 60 C. in differential scanning calorimetry is 30 J/g or more.

Systems and methods which provide an aqueous gel polymer electrolyte having one or more additive therein selected to configure the aqueous gel polymer electrolyte, and batteries formed therewith, for improved performance are described. Aqueous gel polymer electrolytes may, for example, have an additive compound including boron (e.g., a borate ion-containing salt) therein to configure batteries formed using the aqueous gel polymer electrolyte to increase the ionic conductivity of the gel polymer electrolyte. The addition of borax in Zinc-ion battery gel electrolytes of embodiments is configured to enhance the dissociation of zinc ions and anions, and subsequently release more mobile zinc ions. Furthermore, the interaction between borax and divalent transition metal (Zn) in electrolyte according to embodiments may enhance the transportation of mobile zinc ions.
