ELECTRICAL ENERGY STORAGE DEVICE

摘要

Provided is an electrical energy storage device which is compact and can achieve a high capacity of electrical energy. An electrical energy storage device (1) provided with a first electrode (4), a dielectric layer (6), and a second electrode (7), wherein a current collector layer (5) made up of current collector microparticles (5a) comprising metal, semiconductor or surface-modified ceramic is formed between the first electrode (4) and the dielectric layer (6) and also between the second electrode (7) and the dielectric layer (6).
