20110033755 | PROTECTED LITHIUM METAL ELECTRODES FOR RECHARGEABLE BATTERIES - It has long been recognized that replacing the Li intercalated graphitic anode with a lithium foil can dramatically improve energy density due to the dramatically higher capacity of metallic lithium. However, lithium foil is not electrochemically stable in the presence of typical lithium ion battery electrolytes and thus a simple replacement of graphitic anodes with lithium foils is not possible. It was found that diblock or triblock polymers that provide both ionic conduction and structural support can be used as a stable passivating layer on a lithium foil. This passivation scheme results in improved manufacture processing for batteries that use Li electrodes and in improved safety for lithium batteries during use. | 02-10-2011 |
