A famous academic journal recently published an article stating that new progress has been made in the research on the "intermediate state" structure and transmission characteristics in lithium iron phosphate (LiFePO4) lithium batteries. Researchers at two universities in Tokyo University and Tokyo Institute of Technology said the results of the study will help speed up the response speed of lithium batteries and significantly shorten the battery charging time.
A team led by Atsuo Yamada, a professor at the University of Tokyo's Institute of Engineering, found that the electrons surround the stripe-shaped thin film layer without interrupting the lithium ions and the striped thin film layer. In addition, the "intermediate" lithium / electron conductivity is higher and lithium ions and electrons move faster than the charge or discharge states. At present, the team has succeeded in stabilizing the "intermediate" content at 100%, which is conducive to improving the electrical conductivity. Through the new research program, can quickly charge the battery development will usher in a new breakthrough.
A valve that automatically controls the level of a vessel. It is installed in the liquid inlet or outlet of the container, the use of float (usually empty floating ball) in the container float or drop drive valve disc action, by regulating the flow in and out of the container to maintain a certain level of the container. The valve in the figure is a floating ball regulator that controls the inlet flow of fluid. When the liquid level is below the specified value, the float drops to open the disc, and the liquid flows into the container, and the liquid level rises accordingly. When the liquid level rises to the specified level, the float floats to close the disc and the liquid stops flowing in. These valves are used for level control in low pressure vessels.
