ENAX empower progress. Company profile.

ENAX empower progress. We, Enax, provide the safe and high quality Li-ion batteries which is loved and admired by our stakeholders, and contribute to construction of the society with mobility and convenience. Kazunori Ozawa, Ph.D, President and C EO

ENAX empower progress. Dr. Kazunori Ozawa ENAX has been established by Dr. Ozawa, who was the division manager of the Li-ion battery at Sony (the first company which succeeded to commercialise business on Li-ion battery). He sees himself as an engineer, appealing to a society about the importance and the splendid culture of creation and manufacturing. Kazunori Ozawa, Ph.D, President and C EO

ENAX empower progress. Dr. Kazunori Ozawa He has developed a new type of Li-ion battery, i.e. LSB (Laminated Sheet Battery) with his own patents (thus not caught by the Sony patent net). LSB have been accepted worldwide. For instance Mr. Iacocca has praised as the ENAX LSB is the safest Li-ion recharge-able battery in the world!.

ENAX Li-ion: Safety

ENAX Li-ion Safety: Comparison of Battery Structures

ENAX Li-ion: Safety 1. In the event of severe accidental damage The Li-ion battery is a high power battery. In case of an accident, a huge current may lead to an explosion. The ENAX Li-ion battery does not explode in such situations.

ENAX Li-ion: Safety 2. Overcharging The ENAX Li-ion battery does not explode due to overcharging. Normal Li-ion batteries ignite (explode).

ENAX Li-ion: Safety 3. Over discharging The ENAX Li-ion battery has no bulge or leakage of electrolyte in the event of over discharging. Normal Li-ion batteries suffer from bulge or leakage of electrolyte.

ENAX Li-ion: Safety 4. Nail penetration The ENAX Li-ion battery does not explode in Nail penetration test Normal Li-ion batteries explode.
