Solution, this mixed solution continues the cathode chamber for being passed through hot recycling ammonia battery, and as catholyte, the ammonia isolated then leads to
The anode chamber for entering battery participates in the reaction in anode as reactant again.
7. the method for discarding printed electronics wiring board using hot recycling ammonia Battery disposal according to claim 4 or 5 or 6,
It is characterized by: being respectively arranged with cathode side end panel (9) and anode side on the outside of cathode chamber (7) and anode chamber (8)
Plate (10).
