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 market. <\/p>\n<p>The batteries are key for many modern technologies, from smartphones to electric vehicles. However, as these batteries age, they often become less efficient &#8212; a process that cold weather accelerates. The researchers said they could counter this problem with the &#8220;injection&#8221; of a special solution to rejuvenate &#8220;sick&#8221; batteries. At present, lithium-ion batteries rely on sophisticated materials used to generate lithium ions &#8212; whose movement through electrolyte is key to their performance &#8212; and then protect them to ensure a decent lifespan. <\/p>\n<p>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. The battery is considered to have expired when the supply of lithium ions runs low &#8212; for example some electric car batteries have a lifespan of around 1,500 charge cycles &#8212; but other components in the battery still remain in good working order after this happens. This insight prompted the two lead researchers, Gao Yue and Peng Huisheng from Fudan University&#8217;s macromolecular science department, to see if they could revive a battery by replenishing the supply of active lithium ions.<\/p>\n<div class=\"share_submission\" style=\"position:relative;\">\n<a class=\"slashpop\" href=\"http:\/\/twitter.com\/home?status=Scientists+Develop+'Injection'+To+Make+Smartphone+and+EV+Batteries+Last+Longer%3A+https%3A%2F%2Fscience.slashdot.org%2Fstory%2F25%2F02%2F18%2F166204%2F%3Futm_source%3Dtwitter%26utm_medium%3Dtwitter\"><img decoding=\"async\" src=\"https:\/\/www.prime-wow.com\/wp-content\/uploads\/2025\/02\/twitter_icon_large-112.png\"><\/a><br \/>\n<a class=\"slashpop\" href=\"http:\/\/www.facebook.com\/sharer.php?u=https%3A%2F%2Fscience.slashdot.org%2Fstory%2F25%2F02%2F18%2F166204%2Fscientists-develop-injection-to-make-smartphone-and-ev-batteries-last-longer%3Futm_source%3Dslashdot%26utm_medium%3Dfacebook\"><img decoding=\"async\" src=\"https:\/\/www.prime-wow.com\/wp-content\/uploads\/2025\/02\/facebook_icon_large-63.png\"><\/a><\/p>\n<\/div>\n<p><a href=\"https:\/\/science.slashdot.org\/story\/25\/02\/18\/166204\/scientists-develop-injection-to-make-smartphone-and-ev-batteries-last-longer?utm_source=rss1.0moreanon&amp;utm_medium=feed\">Read more of this story<\/a> at Slashdot.<\/p>\n<p><iframe src=\"https:\/\/slashdot.org\/slashdot-it.pl?op=discuss&amp;id=23613541&amp;smallembed=1\" style=\"height: 300px; width: 100%; border: none;\"><\/iframe><\/div>\n","protected":false},"excerpt":{"rendered":"<p>SCMP: Chinese scientists have developed a revolutionary repair technology that could make lithium-ion batteries last over six times longer.
