Lithium-ion batteries have excellent performance, but long charging times are a challenge. Researchers at the University of Tokyo in Japan have developed a new lithium-ion battery electrolyte that can reduce charging time by more than two-thirds.
According to Japan's "Sankei Shimbun" website reported on the 30th, lithium-ion battery charge and discharge process is through the electrolyte in the lithium ion to move between the positive and negative. The concentration of lithium ions in the new electrolyte is extremely high, which is more than four times that of ordinary lithium-ion batteries. Lithium ions can move at high speed in this high-concentration environment, and the time for one charge is less than one-third that of ordinary lithium-ion batteries.
Because of the problem of the electrolyte's voltage resistance, the lithium-ion battery voltage is usually limited to about 4 volts, and the new electrolyte can be stably charged at voltages above 5 volts. Researchers believe that the voltage of lithium-ion batteries can also be greatly increased.
The head of research, University of Tokyo professor Yukio Yamada, said that although this technology is simple, it is expected to improve the convenience of using lithium-ion batteries.
Stainless steel Angle steel is the two sides perpendicular to each other into the angular shape of the long steel. It is mainly divided into equilateral stainless steel Angle steel and unequilateral stainless steel Angle steel, which can be divided into two kinds of unequal thickness and unequal thickness.
Stainless steel Angle steel can be composed of different forces according to the different needs of the structure, but also can be used as a connection between members. Widely used in a variety of building structures and engineering structures, such as beam, bridge, transmission tower, lifting machinery, ships, industrial furnace, reaction tower, container rack and warehouse shelves.
Stainless steel Angle steel is a carbon structural steel for construction. It is a simple section of section steel. It is mainly used for metal components and the frame of workshop. It is required to have good weldability, plastic deformation and mechanical strength in use. The raw billet of stainless steel Angle steel is low carbon square billet, and the finished stainless steel Angle steel is delivered in hot rolled forming, normalizing or hot rolled state.
