Electric Vehicle....

I remembered an article from a while back about new battery tech and silver. Maybe invest in battery component mining cos for the future.
Samsung Presents Groundbreaking All-Solid-State Battery Technology to ‘Nature Energy’

On March 9 in London, researchers from the Samsung Advanced Institute of Technology (SAIT) and the Samsung R&D Institute Japan (SRJ) presented a study on high-performance, long-lasting all-solid-state batteries to Nature Energy, one of the world’s leading scientific journals.



Compared to widely used lithium-ion batteries, which utilize liquid electrolytes, all-solid-state batteries support greater energy density, which opens the door for larger capacities, and utilize solid electrolytes, which are demonstrably safer. However, the lithium metal anodes that are frequently used in all-solid-state batteries, are prone to trigger the growth of dendrites1 which can produce undesirable side effects that reduce a battery’s lifespan and safety.



To overcome those effects, Samsung’s researchers proposed utilizing, for the first time, a silver-carbon (Ag-C) composite layer as the anode. The team found that incorporating an Ag-C layer into a prototype pouch cell enabled the battery to support a larger capacity, a longer cycle life, and enhanced its overall safety. Measuring just 5µm (micrometers) thick, the ultrathin Ag-C nanocomposite layer allowed the team to reduce anode thickness and increase energy density up to 900Wh/L. It also enabled them to make their prototype approximately 50 percent smaller by volume than a conventional lithium-ion battery.



This promising research is expected to help drive the expansion of electric vehicles (EVs). The prototype pouch cell that the team developed would enable an EV to travel up to 800km on a single charge, and features a cycle life of over 1,000 charges.

As Dongmin Im, Master at SAIT’s Next Generation Battery Lab and the leader of the project explained, “The product of this study could be a seed technology for safer, high-performance batteries of the future. Going forward, we will continue to develop and refine all-solid-state battery materials and manufacturing technologies to help take EV battery innovation to the next level.”

I have a preorder reservation on a Rivian R1T pickup - made it a year ago and thus qualified for a Launch Edition vehicle (specially badged with some no-cost accessories). I hope to have it by the end of this year. I also had, and canceled, reservations on the Nikola Badger and Lordstown Endurance. The Nikola will never see production as it was basically a financial Ponzi scheme run by the founder, and if the Endurance is ever made it will be a low-trim vehicle designed for fleets.

I have full faith that Rivian will make it as the next successful EV manufacturer - they have received billions in investment capital from Ford, Amazon, T. Rowe Price, and Cox Automotive among others. Amazon has placed an order for 100,000 electric delivery vehicles with Rivian, and Tulsa is one of sixteen test markets for those vehicles which are on the road now (Amazon testing Rivian vehicles in Oklahoma | Local Business | pantagraph.com). Rivian has announced that the warranty on their vehicles will be comprehensive (bumper-to-bumper) 5 yrs./60,000 miles and drivetrain 8 yrs./175,000 miles, including a guarantee of no less than 70% battery pack degradation in that 8 yr./175,000 mile timeframe (What is the warranty coverage on a new Rivian? - Support Center - Rivian).

I too am concerned about range anxiety when taking the Rivian out of town - but Rivian is also building a network of over 3,500 fast chargers at over 600 sites by the end of 2023 (Charging your Rivian by Rivian - Rivian Stories). These chargers will be capable of adding up to 140 miles of range in about 20 minutes. I've seen estimates of cost for this charge at around $6-$10, depending on price of electricity at the charger. All of their chargers will be powered by renewable energy.

I'm excited to have a vehicle that will do 0-60 in 3 seconds at less than half the cost of an equivalent performing ICE vehicle! And no more oil, spark plug, antifreeze, or transmission fluid changes! Oh - and to address an earlier post in this thread, you cannot add charge, boost, or jump start an EV from a 12V battery in an ICE vehicle - but in the case of the Rivian, if you were to get stranded with zero battery charge left you could recharge via another vehicle towing it. (Same technology as regenerative braking adding power back into the battery.)

I bet you'll love your Rivian. They have their Corp office and two other buildings in my sales territory in Irvine, CA. I see their trucks and SUVs all the time in my area. They are a really good looking vehicle. In my area there is an old Marine base that is being converted into a community, huge park area, sports fields, etc. Some of the runways are still in tact. Last month I watched Rivian doing some testing. Some testing was the 0-60 times and it was incredible how quick the truck is. I think you made a good choice in EV.

But the question was, if you plug into a charging station outside your home, what does it cost, I think. Like do they charge you per kilowatt-hour or something? How many kWH to charge your batteries completely? How many from say 50%? And how far can you go on that?

Those kinds of costs are very difficult to calculate, and hence turn some people off to EVs when you can get readily-available figures on gas vehicles. The unpredicatbility of usage vs efficiency is an issue.

A lot of the motels in colorado have free ports for those staying there. If I were of a certain mind which I'm not, I sue them for not providing free gasoline for my truck while staying there.
Tulsa Costco has free recharge stations as well. Maybe they need sued by gas guzzler owners too.

I’d prob get a flex fuel before going electric. Maybe in a few yrs when technology improves & there is a better understanding of what the political future holds would I consider an electric.

800 KM = 497.097 miles.
1000 charges = a life span of 497,097 miles.
Would the battery give the same endurance at 400,000 miles as it did at 10 miles would be my question.

My aunt and uncle had to replace the battery pack in their hybrid civic at 200k miles. Cost about the same as a motor rebuild, but they just tripped from SWOK to Big Bend and back for $60 in gas. Has me wanting a prius, but i think I'll get more use out of a crf1000l

what did the electricity cost for this trip?

It's not a plug in car.

ok sorry i misunderstood. i thought you meant they made the trip in an electric car. i get it now----the gasoline engine charges the battery so no need to plug it in???? correct?
