More than likely you’ll see it in electric vehicles and utility energy storage first.
"We've made a breakthrough in battery tech" is a news story. "We've increased the battery life in our phone by 5 hours" is a news story. "We've increased our profit margins by 5% by eliminating nickel from the battery in this phone" is not a news story that gets reported, but that doesn't mean the advances in battery tech aren't being used.
It's like the endless stories about new types of transistor. Computers are faster, but our transistors are not made of diamond or nanotubes or DNA.
my phone was lasting about one-day-per-charge 10 years ago... it's about the same today
