Reironisation of the universe after the 'big bang'

Cold update:
''Walked to the coast to take a picture. The cold zapped my iPhone battery from 100% to 3% in 5 minutes once I took it out of my pocket'' - Jason Burg

If we take the 'observed' data from the below article.  The average background temperature of inter-galactic space [average 2 kelvin] of the observed 1.6k [charge?] appearing at the centre of a galaxy - 

[emergent detection point, in amongst the below average background thermal energy of a galactic core - charge at emergent point?]

- surrounded by a balance of the usual cluster of close orbiting stars, I presume that the quantum 'tunneled' emergent cold hydrogen is a snap shot of a big 'bang' scene.

It has been noted that at very low temperatures [near 0-kelvin] electrons have no charge [or are functionally quantum condenate in state]

Resultant from the above article evidence,

Would it be unreasonable to assume that reironisation would require the warming of the electrons of the hydrogen for their [atomic ironisation] energy of potential to be invigorated?
