An important breakthrough by Dr. Wang Changan of Tsinghua University and Dr. Li Ju of MIT promises to extend the lifespan of lithium-ion batteries that power today's notebooks, mobile devices and other gadgets by a factor of four.
The unexpected discovery has the potential to allow for an all-week Apple Watch battery life while significantly extending run time between charges when using your iPhone, iPod touch, iPad or Mac notebook.
Remarkably, a team of forgetful researchers have figured out how to quadruple a li-ion battery’s lifespan literally by accident.
