Ion dynamics in methylcellulose–LiBOB solid polymer electrolytes
A polymer electrolyte system comprising methylcellulose (MC) as the host polymer and lithium bis(oxalato) borate (LiBOB) as the lithium ion source has been prepared via the solution cast technique. The electrolyte with the highest conductivity of 2.79 μS cm−1 has a composition of 75 wt% MC–25 wt% Li...
