Abstract
An electrode composition that includes an electrode material consisting essentially of at least one electrochemically inactive elemental metal and at least one electrochemically active elemental metal in the form of an amorphous mixture at ambient temperature. The mixture remains amorphous when the electrode composition is incorporated into a lithium battery and cycled through at least one full charge-discharge cycle at ambient temperature.
Claims4
An electrode composition comprising:
- an electrode material consisting essentially of aluminum, silicon, and manganese in the form of an amorphous mixture at ambient temperature that remains amorphous when said electrode composition is incorporated into a lithium battery and cycled through at least one full charge-discharge cycle at ambient temperature.
An electrode composition comprising:
- an electrode material consisting essentially of germanium, nickel, silicon, and aluminum in the form of an amorphous mixture at ambient temperature that remains amorphous when said electrode composition is incorporated into a lithium battery and cycled through at least one full charge-discharge cycle at ambient temperature.
An electrode composition comprising:
- an electrode material consisting essentially of silicon, tin, and copper in the form of an amorphous mixture at ambient temperature that remains amorphous when said electrode composition is incorporated into a lithium battery and cycled through at least one full charge-discharge cycle at ambient temperature.
