I’ll believe it when it ships in my phone.

Otherwise the usual response to battery tech news applies: k keep me posted.

You are right, but the pace at which the battery news is coming these days (frequency), has certainly increased many fold.

Can't wait to have 1Kwh under $50 if this "double the capacity" ever actually comes true though!

Many Chinese suppliers are already operating at or below the $100/kWh mark.

It depends on the use case of course. Low cost with no other constraints is good for utilities, medium cost with smaller size and weight for vehicles, high cost/high capacity/small-light for portable devices.

Since the rest of electric cars is essentially designed, I'm looking forward to someone who really cracks the battery problem. It's a real game changer for a large part of everyday life. No wonder the car companies are thinking twice about building new ICE models, the world could change in a minute.

Question: Is there a graphable Moore's Law at work for batteries?

So you don't want to know about _anything_ until it's available inside phones that you can buy today? I personally like to know what may be on the horizon. It's interesting to read about it, and remember it one the day it arrives (or something else does)!

Not the OP, but... Strictly in phones I can buy today? Not really. Plausibly in phones (or something in a normal household) in the next 3-6 months, sure.

I'm just tired of hearing about battery advances in labs that never make it out to me. Just let me know when I should be prepared to change my purchasing decisions.

I don't know, I remember reading 25 years ago about this awesome technology called OLED that instead of blocking light it actually lights up and you can even bend the display!

It would be different if we didn't get the exact same story every week, seemingly.

Web developpers had a similar habit. It eventually got a name: "the javascript fatigue".

More than likely you’ll see it in electric vehicles and utility energy storage first.

Any market usage would be nice. Unfortunately what typically happens is there's an article about a huge breakthrough and then we never hear about it again.

and yet battery capacity keeps on increasing...

"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.

The stories that get reported are almost never in the product that gets shipped.

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.

> and yet battery capacity keeps on increasing...

my phone was lasting about one-day-per-charge 10 years ago... it's about the same today

The processor is atleast 100x more powerful. The display is 100x better. Speakers, cameras, sensors all have advanced. And yet your battery still lasts on one-charge-per-day. That must be surprising.

but it is not 100x as useful...

Might compare capacity?

I would rather have the same phone that I had 10 years ago if it meant that it would last 7 days with today's batteries

I have a feature phone, ironically lasts about 7 days. Recently purchased.

Have you tried turning off your screen, data connection, wifi, gps, bluetooth and NFC? 7 days of battery life is easy...

I haven't figured out how to use my phone with the screen off... what's the trick?
