New battery technology enables battery life over ten years

According to foreign media reports, a new mobile phase medium battery will be available soon. The battery mainly stores energy through organic molecules dissolved in an aqueous solution. The battery is a non-toxic battery and has the advantage of long life and can be used as an alternative to lithium battery. Product. Researchers at the battery are currently working to expand technology production to make it faster to industrialize.

Everyone must have had this experience: When you need to use your mobile phone urgently, you find that it is running out of power. This is really a very crazy thing.

Now, this kind of experience will not happen, because scientists at Harvard University in the United States have recently developed a new type of battery that can store energy in a liquid solution and has a life span of more than ten years.

In addition to its superior efficiency and long life, the new battery is even more incredible, it is not corrosive, and it is a completely non-toxic battery with superior safety.

The new mobile phase cell was developed by researchers from Harvard University's John A. Paulson School of Engineering and Applied Science (SEAS).

The new battery is mainly stored by dissolving organic molecules in a pH-neutral aqueous solution, and the battery can maintain its energy density for more than 10 years. The birth of the battery also announces the era of ordinary flat battery End.

At the same time, this mobile phase battery not only has a long life, no corrosiveness, but also has a very low cost of preparation, and the battery is chemically safe compared to a lithium battery, which means that the battery does not need to be used. A series of additional expenses, such as corrosion-resistant pumps and corrosion-resistant storage tanks, is also an important reason for their low cost.

At present, the main problem of ordinary mobile phase batteries is that the efficiency is very low and the battery is very easy to be worn out if used for a long time, and the new mobile phase battery fundamentally solves the above problems by improving the solvent, and the test shows that the test The battery will only reduce the energy density by 1% in 1000 working cycles, while the average life of a normal lithium-ion battery is only 1000 working cycles.

Michael Aziz, a professor of materials and energy technology at Harvard University, said: "Lithium-ion batteries can't withstand 1000 charge and discharge cycles."

Professor Aziz added: "If anyone can reach this standard, then it can be said that he has changed the world. The battery is widely used, so the research is very cost-effective and also lays a foundation for our future research. The foundation has brought us one step closer to the goal."

Professor Aziz said: "The battery solution used by the R&D team is ferrocene ion, which is a very good charge storage material and is not easy to dissolve. The water-soluble ferrocene ion represents a large class. A substance that can be applied to a mobile phase battery."

Scientists have prepared a more stable, water-soluble and more resistant mobile phase cell by changing the molecular species in the electrolyte. Since the battery is not corrosive, even if the battery leaks, it will not be like lithium. The battery causes the same damage.

Although this mobile phase battery has been developed by scientists, there is currently no commercial sales and promotion.

The US Department of Energy (DOE) has released a development goal for the battery industry, which is to increase the use of wind and solar energy , and to make it more competitive through continuous research.

Imre Gyuk, director of the Energy Storage Research Office of the US Department of Energy's Power Office, said: "This research work is very important for water-soluble organic electrolytes, and lays the foundation for future battery development. The cycle life of the battery reduces the cost of the battery."

The Czech Republic also said: "I expect that mobile cells with high efficiency and long life will soon become the industry standard for basic grid facilities, and researchers are working hard to bring this technology to industrialization."
