Chinese breakthrough pushes battery specific energy past 700 Wh/kg, enough for >1,000 km per charge. The new ratio decouples range from pack mass, letting designers shrink vehicles or re‐allocate space while easing charging infrastructure pressure. #EnergyDensity #Mobility – Powered by FG

@krutonium I mean, #SaltwaterBatteries aka. #SodiumWetCells exist but they have even worse #EnergyDensity than #LiFePO4 cells which are a common upgrade to replace #LeadAcidBatteries and derivatives for combustion-engine cars.

  • #MethanolFuelcell|s solve the charging speed and charging station problem rather easy.

Cuz worst-case gas stations just sell pre-packaged canisters and most likely convert a pump (from selling ROZ100+ bullshit noone buys) to #Methanol and maybe put a water-spray fire extinguisher next to it.

Personally, I think #Methanol #FuelCell will be the way forward simply because Methanol solves the problems of storage, logistics, recharging and scalability quite well without demaning band new infrastructure.

Researchers dismantle Tesla and BYD #batteries and reveal surprising results.

"The most surprising finding : complete absence of silicon in both battery anodes. This discovery particularly shocked researchers regarding Tesla’s cells, since #silicon incorporation typically enhances #energydensity significantly. Industry experts had widely assumed that advanced manufacturers would utilize silicon-enhanced #anodes to maximize performance."

Not that I advocate for combustion engines - far from it.

Also #FuelCell solves the #RangeProblem or rather "#RangeFear" elegantly with existing (or at least trivially convertible) infrastructure, as it's way faster and cheaper to clean a fuel storage tank and pump and converting it to IPCA 99,9% Methanol, which whilst toxic upon ingestion is abundant in nature to the point that unlike #gasoline it's naturally being decomposed by bacteria and fungi.

Cuz that's what happens when someone decided to go completely bonkers in terms of high-end...

@glitzersachen @leanlearnlead granted the faster a battery is charged, the less efficient it is and the more straining it is on the battery chemistry.

But aside from that, there's no reason why #BEV #Charging needs to be more complex than these few steps;

1. plug in the vehicle with a CCS2 plug
2. select the amount of kWh / money one.wants to spend. (being able to abort if the energy price is abdurdly high!)
3. pay with card (NFC+PIN).
4. upon payment confirmation, the vehucle gets charged and the charging station shows an estimated completion timer & offers sending a notification via eMail or SMS.
5. Once completed, the charging station will unlock the plug/socket and send said notification out. In the meantime another customer could just pull the unlocked plug and start their charging.

Just like on a (abeit slow) gas pump!

@burger_jaap the fact that there isn't #mandatory #Transparency like with #Gasoline #Prices (which have to be reported to @BMWK and @[email protected]) is a problem.

  • Given the #EnergyDensity, this makes having or driving a #BEV even more expensive if one doesn't have a #Wallbox (i.e. being a #tennant with no parking space that is allowed to have that as per fire code)...
