This is the most common complaint among all smartphone users- the battery just sucks! Yes.... in today’s world where a person uses his smartphone for almost everything- right from shopping to bill payments, bank withdrawals and deposits. Add to this the many hours spent on social networking sites and checking and replying to official and personal mails- the battery of the phone seldom lasts for more than half of the day.
And that certainly is a great problem considering the dependence of human beings on smartphones nowadays. In order to address this problem, accompany set up by the Massachusetts Institute of Technology (MIT) - SolidEnergy Systems - claims to have built a new kind of rechargeable battery that may end all the “low battery” woes of users.
This battery is called lithium metal battery, it offers twice the energy capacity of standard lithium ion batteries. Interestingly, these batteries are half the size but double the capacity of current smartphone batteries. Qichao Hu, the co-inventor and CEO of SolidEnergy Systems, informed: “With two-times the energy density, we can make a battery half the size, but that still lasts the same amount of time, as a lithium ion battery. Or, we can make a battery the same size as a lithium ion battery, but now it will last twice as long.”
The company was set up exclusively to research and develop more efficient battery technology. The company has plans to first launch its battery technology in drone before moving on to smartphones and then electric cars. In order to increase the capacity of the battery, the first thing the company has done is swapping out graphite for a thinner lithium-metal foil. The second thing is making chemical modifications to the electrolyte that provides the charge. If all goes well, the battery may hit the shelves by 2017.
