Search engine giant Google Inc. is rigorously working in the research and development of better batteries, which the company intends to use for powering up its devices as it mulls expanding its roots into deeper consumer electronics sector.

A small team, comprising only four members, led by Ramesh Bhardwaj, a former battery expert at rival Apple Inc., commenced a research work late in 2012 for testing the batteries that were developed by other firms. These batteries were meant for being used for Google-manufactured devices.

About a year later, the team of researchers began looking at various battery technologies that Google could develop itself, according to the sources.

The search engine company has booked its remarkable presence in different industries over recent years. Ranging from healthcare and transportation sectors to communications and robotics, Google has proved its niche in almost every sector and continues to make rigorous efforts to weed out the minor obstacles coming its way.

With the expansion, Google has also grown its dependence on efficient batteries.

Larry Page, chief executive official of Google, had also talked about the problem of battery life of the mobile devices has a bigger concern for the company.

Several reports, citing Bhardwaj, have said that Google currently owns at least 20 projects that are based on batteries. One of the most ambitious Google projects include the self-driving car, which will run on electrically charged batteries. Another one is Google Glass, which have suffered badly due to a poor battery life.

It is not just Google that is hunting for new technologies to bring significant improvements on its current battery technologies. Some of these bigwigs are Apple, IBM and Tesla. These companies are also working on dedicated research for the same purpose.
