The blanket features an outer layer made from silica and boron nitride, which reflects heat and sunlight, while an inner layer made from aluminium traps heat to keep the car’s temperature constant. In tests, the team found it could cool an electric vehicle by 8°C on a hot day, compared to the outside temperature, andGet a dose of climate optimism delivered straight to your inbox every month.
It could also find use with domestic battery storage systems, energy storage power plants and even buildings, says Cui. “A sustainable energy system relies on energy storage, and energy storage requires thermal management – and then the blanket will be useful,” he says.
