What are the advantages of aqueous lithium batteries?

Advantages of aqueous lithium batteries Aqueous lithium batteries have become the preferred direction for the development of next-generation large energy storage batteries due to their high safety performance, no fire, high ion conductivity, and low cost. The important working principle of the lithium battery is to rely on the migration of lithium ions between the positive and negative electrodes to generate current. This migration is carried out in the solution, which often causes the battery itself to be depleted. Professor Wu Yuping created a new idea: a composite membrane made of polymer materials and inorganic materials, wrapped around metal lithium. And this composite film becomes a random gate through which the potential of lithium ions travels through time and space between the positive and negative electrodes. Wu Yuping said: You can think of it as the potential of lithium ions passing through the membrane, reaching the negative electrode at once, and then directly returning from the negative electrode to the positive electrode. Back and forth. Therefore, Professor Wu also referred to this new discovery as potential crossing. This new type of aqueous lithium battery will become a strong man in new energy products with outstanding safety and durability. The travel distance of electric vehicles equipped with it is expected to reach 400 kilometers, while the travel distance of traditional lithium-ion electric vehicles equipped with the same volume is only 150,180 kilometers. The latest research by Professor Wu Yuping of Fudan University on the aqueous lithium battery system can increase the performance of lithium batteries by 80%. An electric vehicle can travel 400 kilometers in just 10 seconds. This battery is low in cost, safe and not easy to explode. The research team demonstrated this lithium battery system to reporters. A thin piece of lithium metal is tightly wrapped by a special composite film, placed in an aqueous solution with a neutral pH value, and assembled with the traditional positive electrode material spinel lithium manganate in lithium batteries to make an average charge A new type of water lithium battery with a voltage of 4.2V and a discharge voltage of 4.0V. This achievement has greatly exceeded the theoretical decomposition voltage of 1.23V for aqueous solutions. This achievement of Wu Yuping's research group provides the possibility for the development of a new low-cost, easy-to-large-scale processing, safe and environmentally friendly battery system. It is said that the new type of water-lithium battery uses an aqueous solution as the electrolyte, which has enhanced flame retardancy, which makes the battery less prone to heat and heat during use, and has high safety performance; a composite film made of polymer and inorganic materials can reduce the energy of the battery Drop below 5%. It is estimated that if this battery is used in a mobile phone, the same size battery can at least double the talk time of the mobile phone, and the cost is less than half of the original; the same is true for cars, and the pollution to the environment is also higher than that of existing lithium The battery is much smaller. The U.S. Energy Research Institute has taken aim at this research and hopes to reach a cooperation intention with the research group. But he also hopes to cooperate with forward-looking companies in China. The team stated that the new hydro-lithium battery can be applied to all aspects of life. It is hoped that the breakthrough of hydro-lithium battery can finally make consumers feel at ease about safety, accept the cost, and solve the current global hesitation of the electric vehicle industry.
