Are there actually inert (non-flammable) batteries that have a decent energy density for this? I would be worried about having any kind of sizeable lithium battery in an apartment, considering even laptop-sized batteries have enough firepower in them (but at least that one can more or less be picked up and thrown out the window in an emergency).
- bityard 4y agoLiFePo4 batteries are very safe and do not have the thermal runaway problem that LiPo batteries do when they are damaged due to improper charging, abuse, or manufacturing defect.
- jacquesm 4y agoAs long as you stay away from the prismatic ones. If you do use those make sure you only use a properly designed enclosure to contain the forces exerted by the batteries as their charge, there is a reason manufacturers quote battery capacity at 300 or 500 kg clamping force. These are not at all easy to work with.
- Nextgrid 4y agoWhat would be the consequences of non-containment? Do those batteries swell and completely fall apart or do they just move a bit (if so, flexible cables and leaving decent room for expansion should be enough)? Do they merely need the compression to achieve the rated energy densities, or do they fail dangerously because of insufficient compression?
- jacquesm 4y agoThey can fail dangerously because the deformation can cause the busbars to become dislodged. Definitely not just a capacity thing.
