Battery energy efficiency and Coulombic efficiency - what are they?

[QUOTE="essenmein, post: 6288364, member: 647751"] From the internet, coulombic efficiency or Faraday efficiency is the energy lost when electrons or ions participate in unwanted reactions, or if the electrolytic products are allowed to recombine. The other losses in batteries are I2R (current dependent, ie charge/discharge rate) and voltage losses, ie to charge a cell you need to apply more voltage than the cell voltage, then to discharge the load voltage must be less than the cell voltage, this voltage differential is a loss in the system. So energy efficiency is all of the losses put together and is heavily dependent on charge/discharge rate. [/QUOTE]
