Donut Battery Breakthrough - novel discovery, or puffed up ridiculous claims

Featured Replies

Amprius SiCore cells are said to be 450wh/kg as are some via China.

Expensive.But I go back to the point that the Verge Ts Pro is regularly forever delayed so Donut expect any battery to make real production.

    'One per week' sound code for 'no bikes on retail sale this year'

    Like magic. Gone. Just like that.

  • So now for the drip drip of exactly who did what ..., who knew what ..., when, ... how illegal was it anyway, ... (and which of them knew Epstein?)

Seems that is is exactly 3 years since CATL launched its solid state batteries.

Tomorrows 'Super Technology Day' will no doubt have an update alongside one on its production Sodium batteries.

3 years development time tells us about real timelines rather than fantasy promotions.

CATL's SSB biggest competitor is Samsung's SSB. Both use sulfide electrolyte but Samsung use a 5 micron thick silver carbon layer to protect the anode, CATL use much cheaper Lithium fluoride protective layer instead.

Both face huge scrapping cost ramping up production. SSB manufacturing is still low volume, it is reported that 30%-40% of the production don't meet quality control. It is estimated that a 100kwh pack from Samsung would cost around 15k-16k USD, price would drop 20% in 2028 as yield will rise. The switchover from LFP to SSB is expected in 2030.

That new CATL Shenzing seems to do it all.

15C peak 5 min charging. Getting resistance ultra low must signifyhigh round trip efficiency on top of much increased longevity.

SSB will stay niche, CATL admitting development crawl. CATL Naxtra sodium has added 6 months to its timeline.

Main obstacle for adoption of SSBs is cost. They require very high purity for all ingredients.

Suomalainen yritys keksi vaarallisille litiumakuille vaih...

Nordic Nano Group on kehittänyt ympäristöystävällistä akkuteknologiaa, joka voisi korvata vaaralliset litiumakut.

92024, as good as confirming the scam. So the commercial director could not be persuaded to go along with/continue the scam.

Edit - a reddit lists it and others dating back as far as 2021. They even forged one test report !

A comment also mentions cost. About €50,000 for a 1kwh battery.

That'll kill any prospect of donuts for grid use.

As far as I understand the technology: screen printed batteries need clamp shells to prevent them from cracking.

There is no hope that they would displace high volume batteries.
