There is far, far more lithium in the earth’s crust than we will ever need for energy storage. We’re only just now hurting for it because Tesla showed that electric cars are feasible as daily drivers which caused a huge surge in demand. We’ll catch back up in a few more years. And the third world countries that let shitty mining practices take place are what give it a bad name right now. No one wants child slaves in the Congo to mine cobalt for us so we can drive to work. US mines are being built, new processes are being invented, and new battery chemistries that rely less on rare minerals are constantly being invented and implemented.

You’re just being a sourpuss.

source: trust me bro ?

a lithium battery require also cobalt as cathode, it cant solely run on an anode

There are lots of lithium battery types that do not contain any cobalt, such as LFP that is used more and more for electric cars.

more and more

hopefully. still, evs are quite expensive. also the charging infrastrucutre would require a metric fuckton of copper, and that would raise copper prices to silly levels, and its already pricey.

Also Sodium Ion (Na-Ion) batteries are currently in production and could be a viable alternative as the technology advances and production ramps up.

Right now Na-Ion batteries rival only the LFP type of Li-Ion battery (lithium-iron-phosphate) having a lower energy density than other Lithium chemistries. LFP is used commonly in utility power storage for its much greater safety and longevity, but it carries about 20% less power for size and weight compared to other lithium chemistries.

At present the favored battery type for EVs are Lithium types with the highest energy density. Some combine several advantages of the various Li-Ion chemistries having the highest energy density with somewhat greater safety and longevity.

Na-Ion is a new type of battery chemistry with lots of potential for improvement. They use more sustainable materials being cheaper and more abundant. If they could get the Na-Ion battery type within range of presently used Lithium technologies it would be a hugely better solution, a lot cheaper, a lot safer, and much easier on the environment.

Fuck Cars

!fuck_cars@lemmy.ml

Create post

This community exists as a sister community/copycat community to the r/fuckcars subreddit.

This community exists for the following reasons:

  • to raise awareness around the dangers, inefficiencies and injustice that can come from car dependence.
  • to allow a place to discuss and promote more healthy transport methods and ways of living.

You can find the Matrix chat room for this community here.

Rules

  1. Be nice to each other. Being aggressive or inflammatory towards other users will get you banned. Name calling or obvious trolling falls under that. Hate cars, hate the system, but not people. While some drivers definitely deserve some hate, most of them didn’t choose car-centric life out of free will.

  2. No bigotry or hate. Racism, transphobia, misogyny, ableism, homophobia, chauvinism, fat-shaming, body-shaming, stigmatization of people experiencing homeless or substance users, etc. are not tolerated. Don’t use slurs. You can laugh at someone’s fragile masculinity without associating it with their body. The correlation between car-culture and body weight is not an excuse for fat-shaming.

  3. Stay on-topic. Submissions should be on-topic to the externalities of car culture in urban development and communities globally. Posting about alternatives to cars and car culture is fine. Don’t post literal car fucking.

  4. No traffic violence. Do not post depictions of traffic violence. NSFW or NSFL posts are not allowed. Gawking at crashes is not allowed. Be respectful to people who are a victim of traffic violence or otherwise traumatized by it. News articles about crashes and statistics about traffic violence are allowed. Glorifying traffic violence will get you banned.

  5. No reposts. Before sharing, check if your post isn’t a repost. Reposts that add something new are fine. Reposts that are sharing content from somewhere else are fine too.

  6. No misinformation. Masks and vaccines save lives during a pandemic, climate change is real and anthropogenic - and denial of these and other established facts will get you banned. False or highly speculative titles will get your post deleted.

  7. No harassment. Posts that (may) cause harassment, dogpiling or brigading, intentionally or not, will be removed. Please do not post screenshots containing uncensored usernames. Actual harassment, dogpiling or brigading is a bannable offence.

Please report posts and comments that violate our rules.
