摘要:
A conductive-structured electrode is proposed. The proposed conductive-structured electrode includes a tubular 3D electron passage structure made of one or more first-type conductive additives for conducting electrodes; a connecting/continuous conductive 3D structure made of one or more second-type conductive additives for adhering active substances and framing the tubular 3D electron passage structure; and a 3D porous structure formed by the first-type and second-type conductive additives for adhering active substances and framing the tubular 3D electron passage structure. The interior of the stated network-like 3D structure formed by the tubular 3D electron passage structure and the connecting/continuous conductive 3D structure can be used as an ion passage. The network structure itself can increase adhesion of active substances on substrates, and the conductive passage can facilitate rapid conduction of electrons. Thus, the invention is suitable for making batteries, which have increased C-rate performance.
