No. If you look at instantaneous current flow, it will follow the same exponential decay curve as that voltage plot. You'd have a current flow of many amps for the first fraction of a second, declining to a fraction of an amp after several seconds. A battery would supply nearly constant current/voltage until it's depleted.
