Researchers from Peter the Great St Petersburg Polytechnic University in Russia developed a method to increase the efficiency of cathode battery by 15 percent.

The efficiency was increased by adding a solid electrolyte to the battery’s cathode or the positively charged electrode. The discovery will boost the energy productivity and will reduce the weight of the devices that are powered by lithium-ion batteries.

The team demonstrated the result of the findings at a scientific conference in Qingdao, China. The researchers managed to expand the battery’s capacity by 15 percent compared to the one with liquid electrolyte.

“In the framework of the development of energy-saving technologies, clean energy and electric transport, the result obtained in our center hastens the massive introduction of green technologies into the real life,” said Wang Tsinshen from Peter the Great St Petersburg Polytechnic University (SPbPU).

Lithium-ion batteries are generally used in mobile phones, laptops, and electric vehicles, which the scientists claim the new method has potential to increase its efficiency by 15 percent. The team added a solid electrolyte to the battery’s cathode or the positively charged electrode, which helped to enhance its efficiency.

 The researchers conducted experiment in the laboratory to develop the battery on the basis of Joint Innovation Center ‘Science – Technologies’ of Energy New Vehicle (ENV), established in China in collaboration with SPbPU.

“The improvement of cathode materials and functional additives is one of the main tasks of our joint research center,” said Tsinshen, who is also the Director of ENV.
