Google is apparently working on developing batteries that last longer, according to a report by Wall Street Journal. The report further states that Google is also working on specially formulated materials so that batteries can withstand cold temperatures better. Though nothing is officially confirmed yet, but it shouldn’t be a distant possibility as most of Google’s product range require the use of batteries.

The project was initiated back in 2012, when Dr. Ramesh Bharadwaj started testing power sources of Google devices’. Now along with his four-man team, he is trying to make advancements in lithium-ion technology. Moreover, they are attempting to materialize solid-state battery tech, which can be mass produced for consumer products as it’s financially more feasible.

We are quite familiar with lithium-ion batteries as it mostly used in electronics, but what about solid state batteries? Typically, solid state batteries are smaller than lithium-ion batteries, as they use solids to transmit currents rather than liquids. They’re also safer to use as there is no flammable liquid, which is the reason Dr. Bharadwaj and his team plan to use this technology for Google Glass along with X lab’s smart contact lenses. Deploying such battery tech in Google Glass will enable it to play more videos on a single charge, while future smart lens owners can wear them for extended periods of time.

If the report turns out to be true, the search engine giant will join the ever growing list of companies working and researching to improve battery tech. Moreover, with devices becoming more complicated and power-hungry, it good to see big tech giants working on improving battery technology. Apple is reportedly manufacturing its own “large scale battery division” while Tesla is planning to open a gigantic factory to mass produce batteries for its EV’s in the United States.
