Scientists are working on a new battery that can charge as fast as ordinary batteries and is less harmful to the environment. Accordingly, as a result of replacing lithium and cobalt in ion batteries, it is possible to develop a more conscious and harmless technology for the environment and society.
Researchers from the University of Texas in the USA have succeeded in developing a sodium-based battery material partially funded by the US National Science Foundation. It is stated that the newly developed sodium-based material can charge as fast as a conventional lithium-ion battery, potentially has more energy output than existing lithium-ion batteries, and is stable.
Can charge as fast as conventional batteries
The ions in the batteries move between the negative anode and the positive cathode during the electricity generation phase. In sodium-based batteries, however, the anodes can develop filaments called dendrites that can cause short circuits. Thanks to the new technology we mentioned above, it may be possible to prevent this dendrite formation in sodium-based batteries and to charge batteries as fast as lithium batteries.
Anode material developed by forming a thin layer of sodium metal on an antimony tellurium powder and repeatedly folding the layer; It creates a single sodium atom distribution that prevents dendrite formation and corrosion from occurring. In addition, this process also makes the battery much more stable, with a charging rate similar to that of lithium-ion batteries and possibly a higher energy capacity.
David Mitlin, co-author of the study published in the journal Advanced Materials, noted that with the new technology developed, they actually solve two problems at once. “Typically, the faster you charge, the more these dendrites are formed. Therefore, if you suppress dendrite growth, faster charge You can go and discharge,” he said.
On the other hand, the demand for fixed energy storage systems is quite high and increasing day by day. Thanks to this new technology, it may be possible to provide a more stable, sustainable and cheaper solution to the problem in question.
