NANOCOMPOSITE ELECTRODES AND RELATED DEVICES

摘要

A nanocomposite electrode (100) that includes a current collector (110), an electroactive layer (150), a conductive adhesive (130) contacting the surface of the current collector and an interlayer region (140) in electrical communication with the current collector an the electroactive material. The interlayer region is interposed between the current collector and the electroactive layer and includes a portion of the conductive adhesive intermixed with a portion of the electroactive layer. The electroactive layer includes electroactive material having a surface area of at least about 10 m2/g. The conductive adhesive may be at least partially soluble in electrode castin solvent. Electrochemical devices, such as lithium secondary cells, containing an electrode with an interlayer region are also provided, as are processes for making such electrodes and electrochemical devices.
