The lithium battery used today has a maximum life of about 10 years. Earlier, Japan's Sharp and Professor Tanaka Hyun of Kyoto University jointly developed a lithium-ion battery with a service life of 70 years. The long-lived lithium-ion battery produced in this trial, with a volume of 8 cubic centimeters, optimizes the material combinations used for positive electrodes such as iron and silicon by using the latest computer-based simulation technology. From the results of this experiment, the long-life lithium-ion battery can be charged and discharged up to 25,000 times. If it is charged and discharged once a day, the service life can be as long as 70 years. And Sharp said that after the actual charge and discharge of 10,000 times, its performance is still stable. In this way, the life of a lithium-ion battery will be six times longer. Even if used in combination with a power generation device that uses renewable energy, the battery can continue to be used even if the solar panels and wind turbines are updated. Researchers plan to use this long-lived lithium-ion battery for wind and solar power as a large battery. At this stage, wind power and solar power generation are affected by the climate, and the power output will change at any time. If it is matched with the battery, it can ensure stable output and reduce the impact on the power grid. Frequent replacement of the battery is an important factor in increasing the cost of power generation. If a lithium-ion battery with a service life of 70 years is applied to this, the power generation cost will be greatly reduced.
High speed shutter door is a rapid operating, anti-crash shutter door for indoor application . The most advantage of this door is that the opening/closing speed can reach to 0.6-1.8m/s, really fast action a lot than tranditional rollling shutter door. short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
High speed door can be easily installed, economical,quiet and efficient with electromechanical drive.
This door quickly though in/out open gate, ideal for warehouses,factories, hangars use, widths can be from 2m to 20 meters.
The material of this door are variety: PVC curtain to keep the insdie clean, heavy duty aluminum door with wind-resisitant function can wrok in heavy windy weather, and also the freezer door can be used in cold warehouse or somewhere like that.
Including models are:PVC High Speed Door, Aluminum Spiral High Speed Door, Self-Recovery repair door, Cold Storage Room Fast Door.
