Another day, another house burn by an exploding lithium battery. Today's news featured a Mercedes as the biggest lithium battery fire but little batteries have started big fires. I am thinking about all the Pi based projects with lithium batteries. Will the new sodium batteries be safer? Should we use something older?
Heaps of technology uses Lithium batteries and things like notebooks do not explode because the battery controller is built into the battery complete with things like temperature sensors. I see Pi battery setups with the controller from one supplier then batteries from someone else.
Given the high cost of batteries, some people buy from suppliers in China who might not comply with any safety standards that apply in Western countries.
The scooter fires are often reported as someone using a charger of a different brand to the battery.
I am looking at NiMH for my next project as I already have sets of 4 * AA NiMH batteries. There are 18650 size sodium batteries in production but not on sale to the public. Maybe next year.
