As a responsible club, when someone has a problem with a lipo we put in a container of saline solution to discharge it. When we next come to race the packs are then removed and put into the electronic recycling at my work.
When the salt water solution is first created it is nice and clear and you can see the negative battery terminals fizzing.
After a few packs have been put through it, the solution turns cloudy and a thin, pale blue sludge appears in the water.
Can anyone tell me what the blue sludge is.
As the water is acidic, is there electrolysis occurring and producing something alkaline?
As you've guessed, I haven't done any chemistry since school and can remember very little of it.
