Dr.Ozawa battery (R) as Next Generation Li-ion Battery

TO-A1 Dr.Ozawa(R) Battery


TO-A1R Dr.Ozawa(R) Battery Racing version

Dr.Ozawa(R) Battery developed as next generation Li-ion Battery, has world's first feature as following.

 *World First : This battery will be capable to replace Lead battery without any danger

 *World First : Metal case is not required because there is no fear of explosion or danger

 *World First : Safe battery, even if short circuit occurs

 *World First : Safe battery, even if Reverse-Connects +- terminal

 *World First : Unlike Lead battery or existing Li-ion battery, concern is not necessary for complete electric discharge of this battery which is the same as Nickel-Cadmium battery or Nickel-Hydride battery

 *World First : Hyper battery, can perform Multiple connection and Series connection with battery pack

 *World First : Hyper battery, is equivalent to Super Capacitor. Response is very good and Rush Current is the same as Super Capacitor


TO-A20 Dr.Ozawa(R) battery 2.4V20Ah (2016 Spring), now TO-A25 25Ah, and 50Ah will mass product soon

 *Ideal for any kinde of electric vehicless


 *Ideal for various electric care vehicles such as folding electric wheelchairs


 *Ideal for any kinde of UPS

UPS backpack softbag


 *Ideal for any kinde of large scale electric strage

 We are considering a standard unit of 500KW class, and it is a system concept to stack this to the required power size

 Ideal for micro-grids for remote islands, also effective for mobile power systems


Container-type 1MW power storage system under consideration for alliance

Coreless motor

When used as in-wheel, it is ideal for EVs in combination with Dr. Ozawa batteries, and the strongest drone can be made

Due to the coreless design, it is possible to reduce the size and weight of both the output and torque comparisons, and achieve several times the power of the same size motor at both rated output and rated torque

In addition, space saving is realized by incorporating gears using hollow parts for coreless

Magnesium battery

Unless the package is broken, long-term storage is possible and suitable for disaster storagesuitable for disaster stockpiling, and has been delivered to local governments

TM-3 LED Lantern

The following three kinds of Magnesium battery are under developing.

 *Carbon Type

 *Carbonate Type (Coating and Cylindrical shape)

 *Alloy Type

Hybridizing of a Magnesium battery with a Li-ion battery is indispensable because Magnesium battery has characteristics of long time discharge with small current therefore can not respond to Rush Current which requires momentarily big current.

LED Lighting

It is the first LED lighting in the industry without power supply unit therefore electric noise doesn't occur and can control the dimmer, Full life of LED lighting can be secured without obstacle, because there is no reduction of LED lighting's life by degradation of power supply unit.
