Electrode structure

Abstract

The electrode structure 10 comprises interlayer 14, arranged on current collector surface 13 and / or tab surface 15’, comprising a corrosion resistant carboxymethyl cellulose binder and may comprise an electrically conducting single or multi-walled carbon nanotubes. Interlayer 14 may be in electrical contact with electrode layer 16 and current collector layer 12, found between electrically conductive tab 15 and collector layer 12. The tab 15 may comprise aluminium, lie between electrode 16 and current collector 12 with an end surface extending beyond the current collector 12. The interlayer 14 may have thickness that is uniform and between 200nm and 100nm. The current collector 12 may comprise aluminium. A second interlayer (214f, Figure 5) may be in contact with the current collector 12 or the tab 15. A battery cell incorporating the electrode structure 10, a method of making the electrode structure 10, and uses of the interlayer 14 are also described. [Figure 1]
