materials is as follows.

Lithium cobaltic – LiCoO2

・ Acute toxicity : Unknown.

・ Local effects : Unknown.

・ Sensitization : The nervous system of respiratory organs may be stimulated sensitively.

・ Chronic toxicity/Long term toxicity : By the inhalation of coarse particulate and steamy

gas of cobalt, it is possible to cause the serious respiratory-organs disease. The person of

allergy-natured or sensitive-natured may cause a skin reactionary lung disease.

・ Local effects(skin) : Although it is very rare, the rash of the skin and allergic erythema

may result. Graphite

・ Acute toxicity : Unknown.

・ Local effects : Unknown.

・ Chronic toxicity/Long term toxicity : Since the prolonged inhalation under the high

concentration of a graphite coarse particulate may become a cause of a lung disease or a

tracheal disease, it is regulated by the coarse particulate obstacle prevention rule and the

dust-lung method enforcement regulations.

・ Carcinogen city : Graphite is not recognized as a cause of cancer by research

organizations and natural toxic substance research organizations of cancer.

Copper foil
