Abstract
An electrode, a method for preparing the same, a battery, and an electrical apparatus are provided. The electrode comprises a current collector layer having a porous structure and being gas permeable; and an active material layer laminated on at least part of surface of the current collector layer and located outside pores of the porous structure.
Claims18
An electrode, comprising:
- a current collector layer being gas permeable, a surface of the current collector layer having an active material region and a support region extending from the active material region;
- an active material layer laminated on the active material region of the current collector layer;
- a support layer laminated on the support region, the supporting layer comprising porcelain, and the support region being not covered by the active material layer;
- and
- an electrical connection member mounted on the current collector layer and electrically connected to the current collector layer through a connection region, the electrical connection member protruding and extending from an edge of the current collector layer and being separated from the active material layer by the support layer;
- wherein the current collector layer comprises a porous substrate and a conductive layer, the porous substrate comprises a polymer and having a plurality of pores, the conductive layer comprises a metal, the active material layer is located outside the plurality of pores of the porous substrate, and the conductive layer covers at least part of a surface of the porous substrate and covers at least at part of an inner surface of at least one of the plurality of pores of the porous substrate.
