   en.wikipedia.org/wiki/Solar-powered_flashlight

   A solar flashlight with built-in radio. Solar powered flashlights (American English) or solar powered torches (British English) are flashlights powered by solar energy stored in rechargeable batteries. Most of these flashlights use light-emitting diodes lamps [1] [2] since they have lower energy consumption compared to incandescent light bulbs. [3]

   3 (LiMnO 2) 3.6 (LiSOCl 2) 14.0 × 25.0 (nom.) 14.5 × 25.0 (max.) Same diameter as AA battery, used in small electronics, including pulse oximeters, as well as use in some computer models (such as most pre-Intel Macintosh models and some older IBM PC compatibles) as the CMOS battery. Also used in US military MILES gear and DAGR.

   Thus, since the ionic radii of Al 3+ (0.54 Å) and Li + (0.76 Å) are similar, significantly higher numbers of electrons and Al 3+ ions can be accepted by cathodes with little damage. [1] [2] Al has 50 times (23.5 megawatt-hours m-3) the energy density of Li-ion batteries and is even higher than coal. [3]
