Customer ServiceThe rechargeable C cell I mentioned above (1.2v, 2.2Ah) holds 9,500 joules. A capacitor holding this much energy at 1.2v would have to be (2 x 9,500 / 1.2 x 1.2) = 13,000 Farads, so if it helps, you can think of a battery as an enormous capacitor.

Customer ServiceSystems storing energy by faradaic charge storage will show one or more galvanostatic charge/discharge plateaus at the potentials associated with the electrochemical redox reactions. The drop or rapid increase of the potential indicates the end of charge or discharge, respectively.
Customer ServiceFig. 1. Capacitive and faradaic charge storage mechanisms distinguished by their root cause and mass transfer regimes. Faradaic charge storage can be diffusion-limited or non-diffusion-limited. The latter is also called “pseudocapacitive” charge storage, which depends upon the relative rates of diffusion and electrochemical reaction.
Faradaic charge storage occurs due to an electrochemical redox reaction at the electrode-electrolyte interface, across which electrons (charges) are transferred. The redox reaction requires the mass transfer of ions to the interface, and in the two limiting cases, can either be faradaic diffusion-limited or faradaic non-diffusion-limited.
Here, by “pseudocapacitive charge storage mechanism,” we indicate that the fundamental physical nature of the charge storage is indeed faradaic in nature, but whose overall rate of electrochemical reaction is either non-diffusion-limited (D a el ≪ 1) or in a mixed transport regime (D a el ∼ 1) over common experimental conditions.
This double layer capacitance can be mostly neglected in faradaic energy storage devices as it does not contribute significantly to the overall charge storage capacity. Typically, CDL is in the range of 10 to 40 μF cm −2 in batteries with predominantly faradaic diffusion-limited charge storage.
Capacitive charge storage results from the physical separation of charges at the interface of an electrode. An electric capacitor consists of electrodes with an electrically insulating but polarizable dielectric between them.
H. von Helmholtz established the foundation for understanding charge storage and EDLC capacitance with his creation of the electrical double layer (EDL) framework and voltage at the solid-electrolyte interface in the mid-18th century .
