Electric vehicles (EVs) will be able to run over 1,000 kilometers on a single charge in one to two years, said Chen Jun, a deputy to China's 14th National People's Congress (NPC) and an academician of the Chinese Academy of Sciences, at the Deputies' Corridor in the Great Hall of the People in Beijing on Friday.

Chen, also the vice president of Nankai University, shared with the press that his team has developed solid-state batteries with an energy density of about 400 watt-hours per kilogram, 30 percent higher than the currently most advanced 300 watt-hours per kilogram lithium-ion batteries on the market.
