SECONDARY BATTERY-USE ELECTRODE AND PRODUCTION METHOD THEREFOR AND SECONDARY BATTERY

摘要

The invention provides an electrode as a cathode or an anode of a secondary battery. The electrode has a first and a second surface that are electrically conductive and adapted to be brought into contact with an electrolytic solution. The electrode has an active material layer containing active material particles between the first and second surfaces. The electrode has a large number of microvoids open on the first and second surfaces and leading to the active material layer.
