Abstract
An electrochemical device electrode has a current collector, alkalescent resin layers, conductive layers, and active material layers. The current collector is an acid-etched metal foil whose surface has concavities. The alkalescent resin layers are formed and desiccated inside the concavities and exhibit weak alkalinity. The conductive layers are formed on the current collector and the alkalescent resin layers, contain conductive material, and are electrically connected to the current collector. The active material layers are formed on the conductive layers.
Claims9
An electrochemical device electrode having:
- a current collector which is an acid-etched metal foil whose surface has concavities;
- alkalescent resin layers which are formed and desiccated inside the concavities of the current collector and whose pre-desiccated state exhibit weak alkalinity;
- and
- conductive layers which are formed on the current collector and alkalescent resin layers, which contain conductive material, and which are electrically connected to the current collector;
- and
- active material layers formed on the conductive layers.
A method for manufacturing electrochemical device electrode, comprising:
- etching a current collector, which is a metal foil, using an acid, to form recesses and projections on its surfaces;
- applying and then drying an alkalescent resin material on surfaces of the current collector, to form alkalescent resin layers in the recessed parts of the current collector;
- forming conductive layers on the current collector and alkalescent resin layers;
- and
- forming active material layers on surfaces of the conductive layers.
