What is the problem with Tesla battery fans and people investing or interested in other products? No way is VW and other auto manufacturers going to use Tesla batteries in their EVs. So what if there are going to be competing technologies and suppliers out there. Elon and Tesla encourage that in fact. Worldwide there is a huge market and it's not all going to be all Tesla. We're a Tesla family (2 Teslas, Solar and PWs and have Tesla stock--long term holders) so it's not that I am not a Tesla fan but come on. Not everything needs to be compared to Tesla -- to what end? I would think that JB stating they have a breakthough in solid state development and being on their Board should give QS more credibility, here especially. Sometimes I feel like I'm back on the school playgound. Would be nice if this thread could focus on the company and it's product development as time goes on. I think there will continue to be a lot of players in this field and with the ultimate goal of all new cars being EVs, plenty of room to grow. Simplifying manufacturing beyond having a solid working product will reduce costs and garner solid sales if production can keep up to demand. It's a big sandbox.
Investors/traders digesting the recent updates today I guess. With the market down in general surprised to see QS at $71.
Forbes article and interview with Jagdeep. QuantumScape’s Next Step: Multilayer Solid-State Battery Cell Volume Production, CEO Says (Interview)
Wh/L is an interesting way to put it but I'm also curious about the Wh/kg. 800 cycles at near-room temperature with over 90% capacity retention is very good.
When people say energy density they usually mean specific energy (Wh/kg), but energy density is literally the amount of energy per unit volume or Wh/liter. At this point Wh/l and cycle life are probably more important for EVs than Wh/kg, but the opposite is true for applications like aircraft. I have not seen a specific energy spec for QS, but articles say Singh claims >400 Wh/kg. They show a generic chart with NMC811 cathode and Li metal anode a bit above 400 Wh/kg, but that doesn't relate to any specific cell they have made and tested.
Now this was interesting news. I missed reading about the Quantumscape vs Fisker lawsuit when it came out last month in The Verge. The suit can be read on Scribd at the bottom of the article. Fisker quietly settled trade secret spat with VW-backed battery company I did however see Henrik Fisker’s announcement in this subsequent article published the day after the above one was published by The Verge where Fisker was dropping solid-state battery tech because the last 10% leg was too difficult. Hmm. Fisker Inc. has "completely dropped" solid-state batteries Wonder if Choi has been sued. Below is The Verge’s article from March 18, 2019 when Fisker announced their solid-state battery EMotion vehicle would be delayed. Quantumscape’s lawsuit was filed April 12, 2019. Choi would be fired in April and Albano, their battery expert left or was fired in May of 2019. Henrik Fisker delays his luxury sports car and announces "mass-market" electric SUV
