摘要:
A method of forming an electrode of a lithium ion secondary battery includes combining a binder and active particles to form a mixture, coating a surface with the mixture to form a coated article, translating the article along a first plane, cutting a first plurality of carbon fibers, each having a first average length, to form a second plurality of carbon fibers, each having a longitudinal axis and a second average length that is shorter than the first average length, inserting the second plurality of fibers into the mixture layer so that the longitudinal axis of each of at least a portion of the second plurality of fibers is not parallel to the first plane to form a preform, wherein the second plurality of fibers forms a truss structure disposed in three dimensions within the mixture layer, and heating the preform to form the electrode. An electrode is also disclosed.

摘要:
A defrosting or defogging structure includes at least one optically transparent member and an optically transparent composite laminated to the optically transparent member(s). The optically transparent composite includes a thermally and electrically conductive filler material embedded in a polymer matrix. The filler material has at least one dimension on the nanoscale. The optically transparent composite is configured to heat the optically transparent member(s) when an electric current is applied thereto.
