> Previous stretchable batteries have proven sturdy, surviving twisting and even strikes from a hammer. The new battery displays another level of durability, not only enduring stretching, twisting, and folding, but continuously powering a yellow light even while being repeatedly punctured with needles. In addition, “the battery can be cut in half, put together, and self-heal to still maintain more than 90 percent of its capacity”
So (apologies) it can be said that it can resist to battery. Let us note it so this temptation is dealt with. The writer resisted the pun, but indulged in noting that it could power a /yellow/ light - and I am not sure why.
The other big question is: it is obviously good to have a resilient battery as opposed to a fragile one, but where would the resilience of a battery be important or critical, also to justify potential increased costs?
