[RE-wrenches] Exploding LFP battery

[larry at starlightsolar.com]

Damaged Li battery safety, For information only.
Our procedure to decommission any suspect failed LFP cell is to apply small load (<0.05C) until all electrochemical energy is removed. This should preferably be done in a safe area outside. After full discharge, physically damage the cell terminals so it can not find it’s way back into service. 

No stored energy the battery means you just have a container with various elements like Aluminum, copper, lithium, graphite and so forth. See MSDS your battery. Unfortunately, carriers still consider this a Li battery and apply UN hazmat shipping rules. For now, we are storing cells until recycling is cost effective for us.

Hey Jay,

So I don't believe ReLion batteries are openable - so it's most likely that when he decided to open it he cut into it and shorted the leads.

As for recycling - first is health safety!  I'd suggest he contact the manufacturer and get specific instructions for safing the mess.  Will Prowess of DIY Solar Youtube channel had some leaky cells and the manufacturer sent specific instructions to contain and ship back the unit.  You could contact him and he might know but the manufacturer might know better for that specific model.

Hope that helps!

> Very few details...What does it mean "he opened it up"  I would even know how to do that with the L-ions I've been around, seems like its something a manufacturer should be doing.  Temperature?  charge rate? recent usage history? Age? Was it disconnected? Did contacts touch a conductor?........
