Sandy kept feeding him the same questions without realizing it. We want to know how many fast discharge cycles it gets. What does it cost now? What are the projected costs? By when? Which parts of the manufacturing don't scale well? Etc
I loved this. The zen-like calm in this chat seems out of place given things like 0-60 in 1.5s, 0-80% charging in 6 mins, and 50% more range in the same weight of battery pack. This is revolutionary, exciting stuff.
Thanks for this interview. In addition to aircraft, I see a huge market in marine applications. Obviously loading a boat with batteries will dramatically increase the displacement and reduce efficiency. High energy density batteries will be a game changer for electric boats
When you showed that chart that shows battery discharge levels (C) and that Amprius battery can go to 10C, it made me realize why devices "only use half the energy in the battery" going from 100% charge to "no" or "0%" charge. Because zero percent is actually where the voltage gets too low to be usable. If this is right, that means there is only 500 watt hours usable in every 1 kWh in current batteries, but up to 900 or more watt hours in every kWh of Amprius batteries. This means their battery capacity is almost double per watt hour in addition to having more power. Half the batteries needed per mile.
LiPos used by drone racing folks are rated at 60C and actually deliver such currents. Gens Tattu is one brand I'm aware of. How they differ from this Amprius stuff? Only delivering that for a few minutes and maybe a hundred cycles in their lifetime? While Amprius aims for much longer times and higher cycle count?
Amprius has much higher energy density. high energy density batteries tend to have "low" discharge capability, and amprius is starting to touch the discharge rates of common lipos like gens tattu, which have much lower energy densities than amprius batteries. smc racing is better than gens tattu btw.
cool stuff Sandy! super thorough cast! glad to hear that Amprius will get those eAv's running! thanks for the episode! it's hard to believe this ev market is still in it's infancy! good luck everyone!
Apparently, it's not all sunshine and roses in Brighton. I just read about how people in the community are concerned with the usual anxiety: chemicals, fire, and explosion potential. One would think these community members would be overjoyed with the potential of Amprius, the jobs, the technology, and the potential to affect global climate change. No?
The C rate chart is charging only. Tested (not advertised) C rate discharge for common cylindrical cells are between 20C and 3C, with many popular ones in the 11.5C range. Yes, charge rates are lower at 5C or less, most around 2-2.5C
Fascinating information relating to the latest technologies in battery development and implementation. I am curious with the military uses if/are there concerns of keeping “the latest and best” out of the hands of bad actors.
There is a lot of rose colored lens here with this battery technology. Besides cost, which comes down with economies of scale, what is the bad sides? Why doesn't everyone use/license this technology? Seems too good to be true...
Cycle life is only 650, but they're working towards 1,000 cycles. Meanwhile Natron's sodium batteries are good for 50,000 cycles, but their energy density isn't even 100wh/kg.
Why is the market not responding to this major advancement in battery tech? Why isnt this more main stream news or hype about this? Something doesnt add up
they do have data sheets posted on cycle life, and its not great or bad either, its 650 cycles, understand aircraft industry more focused on energy density than cycle life, the general public comments on here crack me up. for me what is the price of this technology? can a guy building a home built aircraft, manned drone or ultralight afford a battery amprious cell flight pack, Tenergy is selling flight packs using amprious cells and its a competitive price. i was easily able to find all this data, so find it like i did. do your research lazy folks!
amprius stock has not done well since it went public, i want success for this company, still too early perhaps, maybe when the y open the colorado plant it will rise again. good luck to all exisiting stock holders
Again military can drive innovation as it, for a non-commercial price, can slingshot the energy-intensive cel technology. Pentagon cost high taxation, but again and again it innovates America (and the world) forward. Drones - a big deal as we see on TV daily. Sadly so btw ...
Sandy kept feeding him the same questions without realizing it. We want to know how many fast discharge cycles it gets. What does it cost now? What are the projected costs? By when? Which parts of the manufacturing don't scale well? Etc
Asking the hard questions!
Thank you Sandy for keeping me on the cutting edge!
Great to hear from Amprius - as I'm a share holder after Munro first covered this company.
Same. I have high hopes for them.
Stock has not been doing well unfortunately.
Just put a GTC/EXT order in at $6.10.
CTO of amprious just sold 80000 shares 5 month ago, not good news
i bet you stock has dropped since you purchased 7 months ago?

This is very impressive!!! Jon is very articulate and clearly Amprius is delivering unprecedented results.
🙋♂️THANKS SANDY AND JON, WE ARE ALL EARS 👂👂 TOO
AND OF COURSE WE APPRECIATE ALL THE REST OF THE MUNRO TEAM EFFORTS 💚💚💚

Thank you for these interviews, Sandy! I can't tell you how much I appreciate it.
I'm wondering what the life of such battery would be in terms of charge/discharge cycles? Especially with the mentioned 6 min charge time to 80%.
Everbody want to know. Its kind of silly to hide that for so long
cool stuff Sandy! super thorough cast! glad to hear that Amprius will get those eAv's running! thanks for the episode!

Life cycle info would be useful.
AMAZING!

Munro and Assoc.should tell your listeners what happened to Cory. He added so much good content to the podcast.
He resigned.
1.5 sec 0-60 sounds like near the limit of traction unless you're talking about drag racing slicks.
When will there be GWH production at acceptable cost????

Very cool
are amprius pouch batteries available for purchase?
There is a lot of rose colored lens here with this battery technology. Besides cost, which comes down with economies of scale, what is the bad sides? Why doesn't everyone use/license this technology? Seems too good to be true...
Exactly. See my questions in the comments too.
Yeah, there must be a drawback somewhere with these batteries they aren't mentioning. Otherwise, we would be hearing of massive licensing deals.
Cycle life is only 650, but they're working towards 1,000 cycles. Meanwhile Natron's sodium batteries are good for 50,000 cycles, but their energy density isn't even 100wh/kg.

15:30 It will be fun to find out that people are literally just paying to have something loud yell at them
If this battery is so good why is the stock price tanking....
`And the CTO just sold 80000 shares... it does not make sense
amprius stock has not done well since it went public, i want success for this company, still too early perhaps, maybe when the y open the colorado plant it will rise again. good luck to all exisiting stock holders
🤗🤩🤩 SOUNDS LIKE A GREAT CANDIDATE FOR ADOPTION 😁💚💚💚
I miss Cory's insights. Sigh.
Everybody want to know what the cycle life is. It's really silly and not very trustworthy to hide that
Again military can drive innovation as it, for a non-commercial price, can slingshot the energy-intensive cel technology. Pentagon cost high taxation, but again and again it innovates America (and the world) forward. Drones - a big deal as we see on TV daily. Sadly so btw ...
Do not sell out to Tesla. Go it alone Amprius
You mean show us that you have something scalable first?
