The development of electricity sustained society is due to the voltage is high-quality energy that is changeable into motive power, light and communication energy. However, the voltage is hard to accumulate, 1: the environmental load becomes more massive when it is generated (large scale concentration type), 2: has a potential hazard of blackout causing an emergency for human life. As the point of realizing a smart society resolving thus two problems, the lithium-ion battery came in the market as the device accumulating electricity as chemical energy.
It is evident that the battery is an essential product for future having background with the big theme.
To be prepared for an emergency, it is essential that the device is used daily. So, set the concept as “the design corresponding emergency but usable daily,” “beautiful heavy duty.” Also, it could contribute to lessening the environmental load (peak shift) and the like.
