An overview of 9 significant advances in battery technology in 2020

As the engine room of much of the modern world, researchers around the world are now focusing on improving the performance of today’s batteries, and to achieve this they are taking every action that can be imagined. Whether it’s building the world’s fastest electrodes, building batteries with nuclear waste, or avoiding the risk of fire with sound waves, 2020 has shown that researchers around the world are very creative and are developing a wealth of different technologies for the next generation of storage space. Have been energized.

Over the past year, several innovative ways have been discovered to improve the performance of electrodes, we found that the use of graphene can make electrolytes stiffer, and advanced materials have led to faster batteries. Let’s take a look at some of the highlights of 2020 in the field of batteries and see how thinking outside the box leads to progress.

When it comes to improving battery performance with new materials, there are plenty of options on the table, but lithium metal has the most potential. Lithium metal, which some have dubbed “dream material,” along with graphite and copper, can lead to more compact batteries today, and the battery not only holds more energy, but also lasts longer.

The main problem is security. As the battery charges, a dendrites form on the surface of the lithium metal, which can cause the device to connect, catch fire, and eventually fail. In 2020, we saw several innovative approaches to solve this problem. Researchers at Washington State University, for example, have been able to prevent the formation of dendrites by adding some key chemicals to the negative pole and electrolyte.

The same innovation led to the construction of a protective layer on the surface of the positive pole of lithium metal, which keeps it stable for at least 500 charge cycles. The University of Washington team now wants to commercialize the invention and add it to battery manufacturing processes.
