Chinese scientists may have found battery that could double electric vehicles’ range
Chinese scientists achieve 700 Wh/kg energy density, potentially doubling EV range to 1,000km per charge.
A research team from Nankai University and the Shanghai Institute of Space Power Sources has published a breakthrough in Nature that could revolutionize electric vehicle technology. Their newly developed electrolyte has achieved an energy density of 700 watt-hours per kilogram in laboratory tests, effectively doubling the performance of current liquid lithium batteries which are approaching their theoretical limit of around 350 Wh/kg. Lead researcher Chen Jun stated that this advancement means electric vehicles with a current 500km range could potentially travel over 1,000km on a single charge, addressing one of the most significant barriers to EV adoption.
The technology represents a major leap beyond conventional lithium iron phosphate and ternary lithium batteries, offering a practical alternative to the industry's current focus on solid-state batteries. According to the research published in Nature, this electrolyte innovation maintains the advantages of liquid-state batteries while dramatically increasing energy storage capacity. The breakthrough could accelerate the transition to electric mobility by eliminating range anxiety and improving reliability in cold weather conditions, potentially reshaping global battery manufacturing strategies and reducing dependence on next-generation solid-state technology that faces significant production challenges.
