Title: The Development of a Polyvalent Battery System
Agency: DOE
Contract: DE-FG02-02ER83579
Award Amount: $99,965.00


70552 Polyvalent battery systems incorporating magnesium or aluminum are expected to have several significant performance advantages (including higher specific energy, energy density, and cycle life) over conventional lead-acid batteries and also be much more environmentally friendly. Such systems also would offer advantages in safety and cost over current lithium-ion battery technology. This project will develop new electrolytes for polyvalent systems and screen them with various cathode materials. The electrolytes will be developed in Phase I by synthesizing new magnesium and aluminum salts. These new salts will be tested for electrochemical stability, conductivity, ability to reversibly deposit magnesium or aluminum electrochemically, and ability to reversibly intercalate/deintercalate from cathode materials. The best materials will be selected and tested in button cells. Commercial Applications and Other Benefits as described by the awardee: The battery cells could be used in high rate applications such as electric and hybrid automobiles, providing a high performance, low cost, safe, and environmentally friendly battery system.
