the positive terminal which has an excess of positive charge

 

I`d be Very hesitant to say it that way, better to consider it Less Negative or Electron Deficient

Cathode produces electrons... I don't know if the same principle applies in batteries but I know that it is a feature of metals that when heated they release electrons, then these electrons are absorbed by anode and this (if I remember) is called thermoelectronic emission...

it applies to cells and batteries (which are just cells wired together).

 

but it`s best not to over complicate matters by introducing CR, that`s an entirely different topic.

Probably! But as soon as I saw electron release from negative terminal ,CR came to my mind. Though I had a doubt of posting or not since it's a bit of off-topic.
