Google Inc. in search of ‘super’ batteries to power its expansion into consumer electronics and other hardware.

In late 2012, a group drove by previous Apple Inc. battery master Dr. Ramesh Bhardwaj started testing batteries grew by others for utilization in Google gadgets. About after a year, the group extended to take a gander at battery innovations that Google may create itself, as indicated by individuals acquainted with the matter.

The group, some piece of the Google X research lab, is little, with only four individuals. A Google representative declined to remark or to make Dr. Bhardwaj accessible.

Google in recent years has moved into commercial enterprises, for example, transportation, social insurance, mechanical technology and correspondences, outlining physical gadgets that require effective batteries. Chief Executive Larry Page told examiners in 2013 that battery life for cell phones is a “huge issue” with “genuine potential to concoct new and better encounters.”

Dr. Bhardwaj has told industry officials that Google has no less than 20 battery-dependent projects. The organization’s most recent heading toward oneself auto runs on batteries energized by power. The principal variant of Google’s Glass Internet-joined eyewear experienced short battery life, which the organization plans to move forward. A push to utilize nanoparticles to diagnose ailments depends on a little battery-fueled checking gadget.

Researchers at Stanford say they’ve made an aluminum-particle battery that takes care of a large number of the issues with lithium-particle and basic batteries. Is this a marvel leap forward? WSJ’s Jason Bellini has.

“Google wants to control more of their own destiny in various places along the hardware supply chain,” said in a statement by Lior Susan, head of hardware strategy at venture-capital firm Formation 8. “Their moves into drones, cars and other hardware all require better batteries.”

Google joins numerous innovation organizations attempting to enhance batteries, including Apple, Tesla Motors Inc. what’s more, International Business Machines Corp. These endeavors have so far created just incremental additions, a complexity for tech organizations usual to customary, sensational jumps in the productivity of semiconductors.

Developing battery advances guarantee greater additions. Strong state, meager film batteries transmit a current over a strong, as opposed to fluid, making them littler and more secure. Such batteries can be delivered in slim, adaptable layers, helpful for little cell phones. Anyhow it isn’t clear whether they can be mass created inexpensively, said Venkat Srinivasan, an analyst at Lawrence Berkeley National Lab.

At Google, Dr. Bhardwaj’s group is attempting to propel current lithium-particle innovation and the front line strong state batteries for shopper gadgets, for example, Glass and Google’s glucose-measuring contact lens, as indicated by the individuals acquainted with the matter.

In a February presentation to an industry meeting, Dr. Bhardwaj depicted how strong state, slender film batteries could be utilized as a part of cell phones and other cell phones that are more slender, bendable, wearable and even implantable in the human body.

For a wearable gadget like Glass, he said, the batteries could help power vitality escalated highlights like feature. For the contact lens, the innovation is more secure on the grounds that it doesn’t utilize combustible electrolyte fluid, Dr. Bhardwaj’s presentation clarified.

Different groups at Google are working with Chicago-built AllCell Technologies LLC in light of more strong batteries for four hardware projects, including Project Loon, the organization’s push to bar Internet signals from high-elevation blow ups, individuals acquainted with the matter said.

A Project Loon feature from late 2013 shows Google architects packaging AllCell batteries into the framework’s energy pack. Lithium-particle batteries perform inadequately in the subfreezing temperatures of the stratosphere, Loon balloons float. AllCell wraps lithium-particle batteries in a wax and graphite material that rapidly retains warmth and spreads it uniformly, developing their life. Google is trying different things with uncommonly defined materials for better chilly temperature execution
