Google has one of the most exciting exploratory labs in its Google X division, but a specific team of four are working on the future of battery technology according to The Wall Street Journal.
The Wall Street Journal reports: "In late 2012, a team led by former Apple Inc. battery expert Dr. Ramesh Bhardwaj began testing batteries developed by others for use in Google devices. About a year later, the group expanded to look at battery technologies that Google might develop itself, according to people familiar with the matter".
We all want to see the battery life on our smartphones and tablets increase by large amounts, with the Google X team working on just that. The Wall Street Journal continues: "At Google, Dr. Bhardwaj's group is trying to advance current lithium-ion technology and the cutting-edge solid-state batteries for consumer devices, such as Glass and Google's glucose-measuring contact lens, according to the people familiar with the matter".
