Smartphone Battery Life Is About to Double

Poor battery life still remains one of the major pain points of modern day gadgets. Whether it’s a smartwatch that barely lasts a day, or a smartphone that offers nothing better than a blank screen by dinnertime, batteries just haven’t kept up with the huge advancements in display and processor technology. Scientists aren’t sitting still,  however, and a new report from Nano Technology suggests things are about to get a lot better.

We won’t pretend to understand the process at work here, but the report suggests that new lithium ion battery technology helps provide for about 99-percent more efficient batteries for “more than 150 cycles.” The secret is how a special coating of “interconnected amorphgous hollow carbon nanospheres helps isolate the lithium metal depositions and facilities the formation of a stable solid electryolyte interphase,” Nature Nanotechnology explained. Thankfully one of the professors working on the project at Stanford University explained that whole process, and the benefits, to Phys.org in much easier terms.

“In practical terms, if we can improve the capacity of batteries to, say, four times today’s, that would be exciting,” former U.S. Secretary of Energy Steven Chu said. “You might be able to have cell phone with double or triple the battery life or an electric car with a range of 300 miles that cost only $25,000—competitive with an internal combustion engine getting 40 mpg.”

Yep, this stuff can’t come soon enough.
