Although initially more expensive, the advantage of rechargeable batteries has always been that they cut down on buying more batteries and they cut down on depleted batteries clogging our landfills.

The company Infinite Power Solutions(IPS) has developed a new range of high-density flexible batteries that could revolutionize renewable energy systems. The manufacturer says these tiny, rechargeable, thin-film batteries combine the energy density of traditional batteries with the high discharge current of supercapacitors. With some models measuring just 0.5in. square (12.7mm) and less than .01in. thick [...]

A new discovery shows that the batteries can be charged very easily by their exposure to sunlight. The inventor Knut Karlsen recently developed the SunCat batteries that are wrapped in flexible photovoltaic panels and will slowly recharge when left to bask in the sun.
