Scientists Develop 'Injection' To Make Smartphone and EV Batteries Last Longer
SCMP: Chinese scientists have developed a revolutionary repair technology that could make lithium-ion batteries last over six times longer. Announcing their discovery in the journal Nature on Wednesday, the researchers said this low-cost, eco-friendly technology could soon be ready to enter the mark...
At present, lithium-ion batteries rely on sophisticated materials used to generate lithium ions -- whose movement through electrolyte is key to their performance -- and then protect them to ensure a decent lifespan. Typically these lithium ions move from the positive terminal to the negative when the battery is charging, a process which is then reversed when it is generating power. This insight prompted the two lead researchers, Gao Yue and Peng Huisheng from Fudan University's macromolecular science department, to see if they could revive a battery by replenishing the supply of active lithium ions.
