This invention describes the preparation of a series of compounds that can be used as co-solvents, solutes or additives in non-aqueous electrolytes and their test results in various electrochemical devices. The inclusion of these novel compounds in electrolyte systems can enable rechargeable chemistries at high voltages that are otherwise impossible with state-of-the-art electrolyte technologies. These compounds are so chosen because of their beneficial effect on the interphasial chemistries formed at high potentials, such as 5.0 V class cathodes for new Li ion chemistries. The potential application of these compounds goes beyond Li ion battery technology and covers any electrochemical device that employs non-aqueous electrolytes for the benefit of high energy density resultant from high operating voltages.
