over the years in which technology has grown many things have become easier and more efficient but one thing always lags behind, batteries. yeah it may seem weird I'm blogging this but I'm kind of interested in all things sci-ency and tech like. but back to the point we've got lithium-ion batteries polymer-ion batteries 1 kilo of lithium stores the same power as a 6 kilo lead acid battery. there is a war between two batteries now which is the refinement of lithium-ion batteries and the other is fuel cell. lithium is the one I'm most interested in as it has been under many different schemes but the most fascinating one is MIT's research into fully organic, virus generated cathodes. its based on the idea how tiny proteins cant naturally bond together to form a perfect structure of a sea shell. by identifying certain viral strains MIT managed to come up with a virus that would automatically organize itself into cathode and anode stacks. fundamentally taking the shape of wires only 6 billionth of a meter in diameter. these tiny wires make for an ultimately thin battery. that is 3 times more potent that a standard lithium-ion battery and more importantly its organic nature makes for a completely green energy source. Standford university is experimenting with another way in which they use silicone nano wires and if they can improve the cathode in a similar way there could be a 10 fold in energy density.
