Lithium production needs investment to keep pace with battery demand Growing demand for lithium for batteries means the sector will need $42 billion of investment to meet the anticipated level of orders by the end of the decade, according to a report. Lithium is used in batteries that power smartphones and laptops, but there is also rising use in electric vehicles which is putting additional …
I've long considered that using a more finite resource than the one we're currently using was a mistake. Lithium isn't a green alternative, what you're not told is how many hectares of forest are being ripped up so smug people can drive around in tesla's (other less smug alternatives are available).

We definitely need to be extracting more from spent batteries than just keep digging up more lithium out of the ground to keep up with demand. But it needs to be cost effective to recycle and not just a well meaning idea that doesn't work economically. As look at plastic recycling which was pushed by the petrochemical companies as a solution to the huge plastic problem, but in reality doesn't work for most plastics as its still cheaper to make new plastic than to use recycled.
it needs to be cost effective to recycle
With current technologies, extracting lithium from batteries is not even close to being economical. There is some recycling of lithium batteries, which sounds good, but they're mainly concentrating on other metals. Major break-throughs are required to change the situation. Until then, hopefully we at least form the old batteries into a pile in the hope of later processing, taking care to avoid chemicals leeching out into the environment and lithium fires.
The way electricity prices are spiralling upwards more and more people are aiming to install solar panels and to get the best out of these you also need to install big batteries at home. The waiting lists of these is shooting up do to supply problems.
Hopefully they'll crack the production problems with sodium batteries soon and that will take a lot of pressure off the lithium supply chain. Sodium is much easier to lay your hands on (not sure what we'll so with all the waste chlorine).
>> Much like you can't take a pile of rust and make iron again.
Ohhhh yes you can.
That's exactly what they do to weld railway rack... OK they use Al powder as well, which makes it not particularly 'green' as a process and there is the small matter of the extreme exothermic nature of the reaction to deal with but, none the less, you can take a pile of rust and turn it back into iron.
icon is flame becasue thats what the Thermite reaction specialises in!
Much like you can't take a pile of rust and make iron again.
actually, iron in nature can only be found rusted, that's why many rocks are red : you cannot find shiny pure iron in the Earth. But that's not a problem: when heated to 1500°C, the iron melts and becomes pure metal again.
Dunno if it works for lithium though
There is sodium battery technology but it's hardly domestic yet. Lithium is safety marginal enough (fires etc) and sodium is much more reactive. It can be managed, it was used as a coolant in some nuclear reactors but I wouldn't fancy 100 kg or so in my basement. I don't know if anyone is working on magnesium, that's much more available than lithium but I guess the chemistry's not so good.
Chlorine can be used for all sorts of industrial processes, notably bleaching, but seems to be considered green only in colour these days!
If by 'green' they mean minimal environmental impact, that's hard to believe. Even DLE only yields 1-2 grams of impure lithium chloride per litre of brine, so vast volumes of water (and masses of electricity) are needed. Conventional evaporative extraction (the dominant current method) is even worse. So however it's extracted lithium is good battery stuff, but very far from 'green'.
