Extremely high energy density batteries?
Are there articles written on exotic, ultimate batteries? I'm not referring to those for hybrid cars, but those that have energy densities up to that of nuclear fuels or higher.
Rather than batteries that operate via chemical oxidation and reduction, is there a theoretical type of battery that provides energy resulting from the decay of certain particles, and the recharging of the battery would be to reverse that process.
Obviously such batteries are not used today because of cost or other reasons.
Could any of you give me some links?

See Radioisotope Thermoelectric Generator. They were pretty popular in the 50's and 60's for remote power generation. The US has since cleaned up most of theirs, but the Russian government seems to have lost track of more than a few. They remain pretty popular for powering satellites.

First, let me say that a Battery is an array of electrochemical cells. Other devices that do not use electrochemical cells are not batteries. However let us assume that you meant energy storage devices.
A fairly good overview of energy storage can be found here: http://en.wikipedia.org/wiki/Energy_storage
Note that none of the examples in that article are nuclear. That simply isn't an option expect in extreme situations, such as spacecraft.
