By coating the iron sulfide cathodes in polymers, a research team was able to create transition-metal sulfide-based lithium batteries with stable cycling and high safety. After 300 cycles, a lithium carbide iron disulfide pouch cell retained 72.0% capacity with no capacity degradation after 100 cycles.

    I really like the safety aspect of this, but 72% capacity after 300 cycles seems low. What’s a use case scenario where this is preferable over lipo batteries?

      Boats, planes, drones, phones, bikes… Anywhere that you can maximize storage cell capacity in odd shaped volumes and spaces/designs. It’s great.

      Having looked at comparative data, it’s not really out of the norm…

      One of the fabricated battery pouch cells was even able to work after being folded and cut off. “That proves its high safety for practical application,” the researchers emphasized.

      If you can cut it in half and it still works I doubt piercing it will do much.
