High-rate and long-life lithium-ion battery with improved low-temperature performance through a prelithiation strategy
When it is cold in winter, cars tend to have starting problems. This is not much better with electric cars, which inevitably lose capacity of their rechargeable lithium-ion batteries at freezing temperatures. Now scientists have offered a strategy to avoid plunging battery kinetics. They have designed a battery system with a cold-enduring hard-carbon anode and a powerful lithium-rich cathode, with the important initial lithiation step integrated. …read more
