Basically I find it good fun taking apart eBike batteries and testing cells as part of my interest in recycling. How-ever apart from this I find no use for them.
Not interested in actually making a powerwall, since I do not have the available space to work safely. Also not interested in...
Gave it a try, no luck, still same amount of swelling.
It looks like the swelling start to occur at 2.5-3.0V, but I will run some more testing to confirm. My biggest issue is not the lack of energy of the battery, but the fact they potentially gain a lot of space and/or could vent gasses or...
Gave it a shot, how-ever no luck. The pressure is great enough to lift the weight:
Did some reading on over-discharging. It seems to be caused by:
I have tried to find a source for proper recycling procedures how-ever none found so-far. Only industrial instructions which is about...
Fair point when I have some more (this was only one battery) and cells are still decent quality (this ones where not) I will do it. How-ever I am based in "The Netherlands" (Europe region), which afaik not many persons are active in the marketplace.
Nice tip, thanks I will give it a try.
My e-bike harvesting also left me with some pouch batteries, which I do not want to use and are thus candidate for recycling. I order to recycle them safely I want to discharge them to avoid issues on an accidental short-circuit for example.
I currently deep-discharge them by hooking them to a...
One reason of joining was to investigate 'waste-streams' generated by (e-Bike) batteries packs. To my knowledge they are not mass-recycled and/or dismantled. Basicly just collected and stored. In NL a non-profit organisation Stibat is responsible for gathering this battery packs.
I retrieved some odd looking batteries from a e-bike battery.
Their identification is GP4105054T1000L.
The only reference I could find are the GP recycle instructions
which tells me the cell is rated 3.65V and 10Ah.
I am completely new in cell harvesting and testing...
I think it a Bronze one. I have one glued like the Dretje, which has bronze listed on the label.
All others Gazelle batteries are easier to open, for example:
They contain different battery packs (stored inside the container) including one which contained flat cells.
