Best non-lithium battery technology Answered
Hi Instructables community! I am looking for any insight / suggestions regarding what battery technology (non-lithium) that offers the best specific energy (MJ/Kg), preferably rechargeable and reliable. My research led me to looking to consider rechargeable alkaline batteries, given data on wikipedia (the BEST source ;) ) but are these even manufactured? I cannot find any place to buy them.
I am in need of this for the design for the solar car team at UVa, as the BMS (Battery Managment System) mandates a backup battery that is separate and any lithium technology is not allowed.
