Using the internal search engine: search.php
We got a lot of results: googlesearch? q = battery

And above all we find this:

I read on a forum that the batteries used for the storage of electricity supplied by an individual wind turbine would only have a lifespan of 5 years.
It seems weak to me and in any case not profitable.
What do you think?

: Arrow: We discussed the subject at length HERE and I made my modest contribution to it. :?

New atomic energy battery
Unlike chemical batteries such as lithium-ion batteries, atomic energy batteries are physical batteries with significantly higher energy density – 1 gram of battery is capable of storing 3 watt-hours of energy.

Another interesting innovation for EV and stationary storage:

Interesting but ultra low unit power (well we can put x, y in parallel series...you already need quite a lot, 100, to obtain 000W continuously or 10*10x3600 = 24 Joules per day)

It generates energy every second, producing 8,64 joules of energy per day and 3 joules per year.


3 Joules per year over 153 years is 50 joules…or 157 wh…and not 650…

It reminds me of NASA plutonium batteries...

There is still progress to be made. I will actually need a batch of 40 million to run the dishwasher + the washing machine, or 45 m³.
But the intention is good. β- radiation is not very bad, and what's more, they are ready-to-use electrons! It remained to find out how to recover them without going through thermal, and now it seems that they have found the trick.

Perhaps an error of interpretation...
On the manufacturer's website
Zhang Wei, president and CEO of Betavolt, said the first product the company will launch is the BV100, which is the world's first nuclear battery to be mass-produced, with a power of 100 microwatts, a voltage of 3 V and a volume of 15 x 15 x 5 cubic millimeters, which is smaller than a coin.
Nuclear batteries produce 8,64 joules per day and 3 joules per year
https://www.betavolt.tech/359485-359485_645066.html

If we stick to the characteristics of the BV100 and not what concerns nuclear batteries in general, it produces 2.4 Wh/day and over 50 years: 43,8 kWh.
It's more of a battery since it doesn't recharge. :?:

For the rest, the translation is messing up
the energy density is more than 10 times that of ternary lithium batteries, and it can store 3 Haowah in a 300 gram battery
:?: :?:

In the series of new features (good if we consider that a publication date of the article in November 2023 is still new), I just saw this:

https://www.geo.fr/environnement/pourquoi-nouvelle-batterie-sodium-ion-northvolt-white-prussian-carbone-pourrait-chambouler-secteur-vehicules-electriques-217629

A battery in which rare metals are replaced by sodium, which would solve the problems linked to them. They could, if their development continues on the right track, prove interesting for the electric mobility sector : Idea:

Now to see what it looks like in reality Image

Well no...100 microW = 1/10 of mW...that means that it takes 100 (or 000 kg if each weighs 100g) to make 1 W...

There is no worse in terms of power per mass in the world of batteries...and yes, it's not a battery, it's a cell...
