In a smartphone world of 5.5-inch HD screens, quad-core 1.5 GHz processor that rival old computers and more one thing that is still truly holding smartphones and tablets hostage is the battery life. Whether it be Android, iOS, or anything else for that matter battery technology has only come along so far, and that isn’t much. However, A new crushed silicon technique could see our battery life triple without using more real estate.

Lets be honest. While technology as a whole has been improving by leaps and bounds our battery life hasn’t. This is a massive selling point for devices with smaller screens, or happy-medium devices like the Motorola DROID RAZR MAXX HD with a massive screen and a huge 3,300 mAh battery. Most users are lucky to get an entire day out of their smartphone in this connected world we live in, but that could soon be changing.

Interesting news appeared today on SlashDot detailing a new crushed silicon method that could potentially triple our battery life, and soon. While I’m obviously no battery expert the details revealed were quite interesting. Instead of using the usual graphite anode construction many commercially available lithium ion batteries use, an improved silicon method has been developed.

Apparently silicon has been in the mix for an excellent alternative and perfect material because it holds up to ten times more lithium ions than graphite, but has a few issues preventing it from currently being used. Surface area expands under certain circumstances, and previous silicon anodes didn’t have enough surface real estate to reliably cycle battery life. Well, Engineer Sibani Lisa Biswal and research scientist Madhuri Thakur have discovered that using silicon sponges and crushing them to get more surface area without adding size, have been able to produce functional batteries with up to 3x the battery life of current options. This is all pretty technical stuff, but if our smartphones can stay the same — or get thinner — while lasting 4-5 days and beyond we’re all for it.

Current graphite anodes can handle around 350 mAh per gram, but this new technique allows for over 1000 mAh per gram. I don’t know about you guys, but this sounds excellent. The team is working to find the optimal materials and hopefully this can be one of the next major breakthroughs we’ve all been waiting for. That goes for the mobile market, hybrid smart cars, and everything in between. Interesting stuff right?
