Polythiophosphonate Electrolytes for Rechargeable Magnesium Batteries

75571-Safety is a key concern in the development of higher energy density rechargeable battery systems, such as used in electric and hybrid electric vehicles. This project will identify a superior non-aqueous, aprotic electrolyte that can effectively support the development of practical, rechargeable magnesium batteries. Phase I will demonstrate the feasibility of using designed poly(thioether-oxyether) phosphonates as superior, high-ion-transfer-rate electrolytes in rechargeable magnesium battery systems. The electrochemical and thermal (safety related) properties of the new systems will be evaluated. Commercial Applications and Other Benefits as described by the awardee: The new electrolytes should be applicable for use not only in vehicular batteries but also in a variety of consumer electronics markets.
