Energy conversion and strage

Resent develop in Lithium Ion Batteries require higher energy density which usually result in lower safety of batteries. The main safety problem is due to combustibility of electrolyte and other parts (for example separator, Al foil positive electrode current collector) used in batteries.
To avoid or to reduce speed of reaction between electrolyte and charged electrodes, completely incombustible or low combustible solvents should be used in electrolyte. However,

using of incombustible solvents result in extremely lower conductivity of obtained solutions. Such a low conductive electrolytes are difficult to be used in practical Lithium Ion batteries. But why the conductivity becomes drastically low?
To find the explanation for that, the ion solvation in obtained solutions is currently under analysis. The goal is to propose completely safe (non combustible) and practically useful (compatible with commonly used negative and positive electrode active materials) electrolyte for Lithium Ion Batteries.
At this time, fluorinated phosphoric esters seem to be most promising solvents.
