Modern batteries have an assortment of problems--from wearing out to burring up (literally).  The goal is to create batteries which can store a great amount of chemical energy.  [[Lithium]] anodes offer this option, since Lithium is such a small atom, which is also in plentiful supply.  However, unlike its predecessor materials, Lithium metal forms dendrites (fibers protruding from the surface) as it gives up and regains atoms. As these dendrites grow, they eventually can connect to the cathode, causing a short-circuit.  When this happens, the battery rapidly discharges and heats up, quite possibly to the point of combustion.  The work-around for this problem which is currently being used is placing lithium ions in graphite as a "framework".  This is two-thirds less efficient than a solid lithium metal anode, but still is better than that the alternatives.  This "dendrite problem" has been the cause of a sort of development race among battery designers--whoever finds an efficient way to stop the formation of dendrites stands to make a lot of money.<ref>http://newscenter.lbl.gov/2013/12/17/roots-of-the-lithium-battery</ref>
