ENAX – empower progress.

“We, Enax, provide the safe andhigh quality Li-ion batteries whichis loved and admired by ourstakeholders, and contribute toconstruction of the society withmobility and convenience.”



Dr. Kazunori Ozawa

ENAX has been established byDr. Ozawa, who was the divisionmanager of the Li-ion battery at Sony(the first company which succeeded tocommercialise business on Li-ionbattery). He sees himself as anengineer, appealing to a society aboutthe importance and the splendidculture of creation and manufacturing.

Dr. Kazunori Ozawa

He has developed a new type of Li-ionbattery, i.e. LSB (Laminated SheetBattery) with his own patents (thus notcaught by the Sony patent net).LSB have been accepted worldwide.For instance Mr. Iacocca has praised as“the ENAX LSB is the safest Li-ionrecharge-able battery in the world!”.


Agenda

ß Coporate profile

ß Empower progress: ENAX Li-ion Batteriesß Technologyß Productsß Safety

ß New possibilities and solutions



Corporate Profile ENAX Inc.

Established 15 April 1996Capital 507 Million Yen (June 2004）Representative Kazunori OZAWA, Ph.D.HQ Bunkyo-ku, TokyoBusiness Scope Development, production

and sales of Lithium ionrechargeable battery packand applied products



From R&D to Mass production

We expanded our service areas to manufacturing andsales of Battery-Pack, to sales of proprietary Li-ionbattery. Striving to shift from a R&D contract typecompany to R&D and manufacturing type company, wehave defined the last year as the beginning of secondphase of ENAX establishment.



From R&D to Mass production

Since last year, we have expanding YonezawaLaboratory to enhance our R&D activities aswell as to establish the mass productionsystems.In addition, big developments were made inChina. Anqiu factory has started its productionof electrodes from this summer 2005, and atTianjin, we are starting the assembly of LithiumPolymer battery by the autumn 2005.



Business Fields.

ß R&D, manufacturing of samples, evaluation anddistribution of large size Li-ion rechargeable battery(Laminated Sheet Battery)

ß Manufacturing and distribution of battery packß Manufacturing and distribution of electrodesß Import and distribution of Electric Bikeß Manufacturing and distribution of Electric Mini Car



Our solutions.

High demands of Li-ion rechargeable battery cells still continue.By utilizing the characteristics of lightness on Li-ion batteries, theapplications vary from PC, Mobile phone to Robot, industry uses,and automobile and so on and so forth.

Fully exploiting our own R&D accumulated experiences andtechnologies, ENAX provide mid to large size safe, high power andhigh energy batteries.



Our spirit.

Within ENAX, we all share the battery engineer spiritwhich we define as the never exhausting spirit ofcontinuously keeping challenging to the limits andseeking for the best battery.



Our overall goal: empower progress.

ß By superior technologies and innovationsß By reliable treatmentsß By strong and personal partnerships and networksß By personal and technical certitude

Together with our costumers –for today and future markets.

ENAX Li-ion: Safety


ENAX Li-ion Safety: Comparison of Battery Structures


ENAX Li-ion: Safety

1. In the event of severe accidental damage

ß The Li-ion battery is a high power battery. In case of anaccident, a huge current may lead to an explosion.

ß The ENAX Li-ion battery does not explode in such situations.


ENAX Li-ion: Safety

2. Overcharging

ß The ENAX Li-ion battery does not explode due toovercharging.

ß Normal Li-ion batteries ignite (explode).


ENAX Li-ion: Safety

3. Over discharging

ß The ENAX Li-ion battery has no bulge or leakage of electrolytein the event of over discharging.

ß Normal Li-ion batteries suffer from bulge or leakage ofelectrolyte.
