Lithium-ion batteries have certainly been a boon to electronic devices, offering much longer run times than their alkaline counterparts. There is still room for improvement, however. Existing lithium batteries can short circuit, they don't stand up to damage, and they can only be made in a limited variety of shapes. Now, scientists from the University of Leeds have developed a polymer gel that could be used to make lithium batteries with none of those shortcomings - plus, they should be cheaper.
