Portable electronic technologies all require electricity to operate and have been limited in their operation by the amount of energy a reasonably sized portable power source can provide. Throwaway primary batteries work well enough, but lack rechargeability and become costly over time due to replacement including added weight to carry as spares for long term missions. Rechargeable batteries such as Lithium Ion have been sucessful in providing increased energy over aqueous based batteries, however all rechargeable batteries are limited to less energy than primary batteries and require an external charger and power source (power grid, vehicle alternator, generator power, renewable energy source) to recharge. Since most of these recharging sources require fuel the added logisitcs to supply energy increases. So what are the choices for an expeditionary future? Renewables such as wind and solar offer some promise, but their footprints are large relative to battieres for proving energy. Using renewables to recharge batteries is also limited by the amount of extra weight and space needed (ie. for solar panels and charging cables) and due to the inefficient nature of batteries to be recharged, requiring a long time. Fuel cells offer increased energy density over batteries for long missions, but are limited to operation on fuels that still require a logistic trail. What is needed is a lightweight renewable high energy density power source that can recharge itself quickly and efficently without external chargers or fuel. One such idea, the Solar Battery has been discovered which takes advantage of the sun to directly recharge the battery insitu without the need for an external power source. By designing a battery to use a dye-sensitized solar cell within the battery as the anode/cathode active component, where the dye is tuned to the wavelength of sunlight it is possible to capture the sunlight and convert it to electrons. Those electrons are then able to directly recharge the electrode active materials chemicially within the solar battery. Since this is a chemicial process it is very fast and efficient relative to the electrochemical process for charging using an electrical circuit and external power source. By designing this approach to work with the very high energy density Lithium Air chemsitry (which has a theoretical energy density on the order of gasoline) one can invision a light weight 5-6 times greater high energy renewable battery that charges itself. In addition, imagine its use in an electric vehicle that has long range and uses sunlight to refuel, or an electronic device that does not need a charger, power connectors or wires, or a UAV that only needs to fly above the clouds to stay aloft.
