Batteries that charge 10x faster and last 10x longer just 5-years out, scientists say

Fat battery pack accessories may soon be a thing of the past. Scientists at Northwestern University are tweaking lithium-ion batteries to last 10 times longer and charge 10 times faster than the battery technology used today, BBC reported recently. Better yet, the new tech could be on the market in just 5 years. Oddly enough, it appears that poking “millions of minuscule holes” that are just 20-40 nanometers wide, and changing the movement and density of lithium ion cells, helps to add battery life and speed up the charging process. A prototype phone battery in Northwestern’s labs can be fully charged in just 15 minutes and it lasts an entire week on a single charge, BBC said. Dr. Harold Kung, the lead scientist on the project, explained that the speed and density of lithium ions can be changed using different materials during the battery’s manufacturing process. “Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium-ion batteries on the market today,” Dr. Kung said. Unfortunately, battery life begins to decline quickly after about 150 charges with the technology in its current state.
