Tianjin Chen Jun Vice President of Nankai University said this on the sidelines of the legislative assembly session of the People’s Republic of China, Ukrinform reported, citing CGTN.

According to Chen, his team has developed solid-state batteries (which use solid electrodes and solid electrolytes rather than liquid or polymer gel electrolytes as in current lithium-ion or lithium polymer batteries) with an energy density of about 400. Watt hours per kilogram is 30% higher than the state-of-the-art lithium-ion battery with a density of 300 watt hours per kilogram.

At the same time, he noted that scientists aim to achieve a breakthrough in the research and development of solid-state batteries in the next one to two years and create a battery with an energy density of 600 watt-hours per kilogram. Electric cars can travel more than a thousand kilometers on a single charge.

Chen also said that Nankai University, one of China’s top classical universities, has developed a flame-retardant electrolyte that can operate stably around the clock in a wide temperature range of minus 70°C and above.

He added that safe, high-performance batteries are vital for both electric vehicles and the electricity storage industry.

The publication notes that today many countries of the world are focusing on the development of solid-state batteries, which could significantly change the future of electric cars and find application in other fields, such as electric aviation.

According to Ukrinform’s report, Chinese automobile manufacturer BYD introduced the luxury electric supercar Yangwang U9, which is expected to rival Ferrari and Lamborghini.
