Are there many situations at this point where maintaining current levels of battery life is a bad thing while not heavily effecting the market? Phones and many laptops happily last a day, and more powerful laptops and vehicles are striving quite hard for extra battery life. That doesn't really leave much else.
Agreed, but with a caveat. Power and weight are probably the two most important battery criteria, but not the only relevant ones. Another would be cost. This development appears to be based on materials technology, which means no expensive retooling of manufacturing, so provided the cost of materials hasn't rocketed, cost shouldn't be much if any different,
Another difference, potentially at least, is longevity. If this relies on an ultra-thin anode, does that affect battery longevity? I don't mean power from a charge, but the number of times a battery can be recharged before you bin it and buy a new one. It's not unknown for anodes to be somewhat sacrificial, at the electron level, and for what can be expensive batteries (like laptops, big drones, etc) I sure don't want to be replacing a couple of £100+ bstteries every few weeks or months because the ultra-thin anode won't recharge as many times.
This new tech sounds great, but the cynic in me wants to get hold of a couple and do some extensive testing before getting too excited by company PR. Been had like that before, so now, before buying a horse, I like to walk round, count the legs and verify that there's one on each corner. And then test-drive it. Twice.
