Scientists have been able to improve the efficiency of liquid batteries

Учёным удалось улучшить эффективность жидких батарей (3 фото) Stanford University has developed a new model of in-line batteries based on liquid metal. Compared to analogues, they are safer and more durable. To do this, American experts have updated the familiar scheme of liquid batteries. The working team also has an engineer from Russia Andrei Poletaev. Учёным удалось улучшить эффективность жидких батарей (3 фото) As the cathode, the engineers used an alloy of sodium with potassium, which remains liquid even at room temperature. The energy density of this compound is incredibly high – about ten times more than other compounds of this kind, previously used in the production of liquid batteries. The novelty has a ceramic membrane coated with aluminum and potassium oxides. Учёным удалось улучшить эффективность жидких батарей (3 фото) Experts have found that it is such a membrane that is extremely selective for sodium ions. She just doesn’t let them to the anode. The most complicated development was a curious fact. This membrane reached its maximum efficiency at a temperature of about 200 ° C, but even at room temperature the prototype showed good results. Scientists performed a series of experiments with the thickness of the membrane, achieving a significant increase in the power of the invention. During testing in the laboratory, the prototype liquid battery was able to work without fail for about one thousand hours. At the same time, engineers doubled the maximum voltage relative to other analogues. According to the authors of the project, the technology can be scaled, its potential for modernization is quite large., Newatlas.com
