Abstract
An active anode (10) is provided that includes a framework (11) of a first anodic material which contains large cavities (12) that include particles (13) of a second anodic material. The cavities have to be large enough so that a fully lithiated particles of the second anodic material fits into the cavity that contains it and does not apply stress to the framework. The first anodic material has a lower lithium intercalation potential than the second anodic material. To produce the anode cavities the second anodic material is coated with an organic coating which is then removed once the anodic layer is produced from a mixture of the first and second anodic materials.
