How delicate is it? etc
The discharge process requires oxygen, which I assume would come from the atmosphere for any simple applications. Given the apparently delicate chemistry, would there be any atmospheric pollutants that might 'poison' the battery? I'm thinking about nose to tail commuter traffic.
Given that oxygen is a consumed reactant, how much oxygen would be needed to generate adequate power for a car to accelerate in town traffic? The battery might need a compressed air supply to give adequate power for practical applications.
The charging process generates 'waste' oxygen .... be careful.
