Establishment / Revision: Dec.1 2008
4/5
11. TOXICOLOGICAL INFORMATION
There is no available data on the product itself. The information of the internal cell materials is as follows.
Lithium metal oxidate –Li(Mn-Co-Ni)O
2
Acute toxicity: No applicable data.
Reference cobalt: LDLo, oral - Guinea pig 20mg/kg
manganese: LD50, oral - Guinea pig 9000mg/kg
nickel: LDLo, oral - Guinea pig 5mg/kg
Local effects: Unknown.
Sensitization:
The nervous system of respiratory organs may be stimulated sensitively.
Chronic toxicity/Long term toxicity:
By the long-term inhalation of coarse particulate or vapor of cobalt, it is possible to cause the serious
respiratory-organs disease. Skin reaction or a lung disease for allergic or hypersensitive person may be
caused.
By the long-term or repetitive inhalation of coarse particulate of Manganese Oxide (MnO
2
), lungs and
nervous system may be affected; bronchitis, pneumonia, nerve disease or nerve mental disorder
(manganese poisoning) may be caused.
Nickel Compounds belong to the 1st group of the carcinogen in the IARC category (substance which
has carcinogenic to man).
Skin causticity: Although it is very rare, the rash of the skin and allergic erythema may result.
Aluminum
Local effects: Aluminum itself has no toxicity. When it goes into a wound, dermatitis may be caused.
Chronic toxicity/Long term toxicity: By the long-term inhalation of coarse particulate or fume, it is possible
to cause a lung damage (aluminum lungs).
Graphite
Acute toxicity: Unknown.
Local effects: When it goes into one’s eyes, it stimulates one’s eyes; conjunctivitis, thickening of corneal
epithelium or edematous inflammation palpebra may be caused.
Chronic toxicity/Long term toxicity:
Since the long-term inhalation of high levels of graphite coarse particulate may become a cause of a
lung disease or a tracheal disease.
Carcinogenicity:
Graphite is not recognized as a cause of cancer by research organizations and natural toxic substance
research organizations of cancer.
Copper
Acute toxicity:
60-100mg sized coarse particulate causes a gastrointestinal disturbance with nausea and inflammation.
TDLo, hypodermic - Rabbit 375mg/kg
Local effects:
Coarse particulate stimulates a nose and a tracheal.
When it goes into one’s eyes, the symptom of the reddening and the pain is caused.
Sensitization: Sensitization of the skin may be caused by long-term or repetitive contact.
Reproductive effects: TDLo, oral - Rat 152mg/kg
Organic Electrolyte
Acute toxicity:
LD
50
, oral - Rat 2,000mg/kg or more
Local effects: Unknown.
Skin irritation study: Rabbit - Mild
eye irritation study: Rabbit - Very severe
12. ECOLOGICAL INFORMATION
Persistence/degradability:
Since a battery cell and the internal materials remain in the environment, do not bury or throw out into
the environment.
