After 300 cycles, a lithium carbide iron disulfide pouch cell retained 72.0% capacity
Put that on a phone and the battery will degrade almost 30% in one year… seems a lot tbh.
But, do they cause a runaway thermal reaction if pierced?
I demand spicy pillows, not mild ones
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.
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?
Much more stable chemistry. In stationary applications, like UPS systems and off grid electrical systems, lead acid is still the standard, due to having stable chemistry, very unlikely to catch fire, and a cost to capacity ratio that is still very good.
The degradation seems pretty bad, but if it’s stable from 300 cycles onwards, you could take 75% as the actual capacity of the battery.
Boats, planes, drones, phones, bikes… Anywhere that you can maximize storage cell capacity in odd shaped volumes and spaces/designs. It’s great.

Why do you think they’re called D batteries? 😏

Having looked at comparative data, it’s not really out of the norm…
it is so interesting to learn just how far behind articles like this are
I bet if you cut it vertically the lights will go out.
Big if true
