Batteries for power storage

Post by Tero » Fri Oct 22, 2021 1:55 am

Cost and weight has been an issue. Certainly not lighter but cheaper:
According to Tesla's Q3 Update, the new battery chemistry of Lithium, Iron, and Phosphate (LiFePo) or LFP power pack would soon be applied for other Tesla vehicles. It would not be exclusive to Tesla China and the Model 3, as it is the new power packs that would replace the long-running usage of lithium.

Said Peter...what you're requesting just isn't my bag
Said Daemon, who's sorry too, but y'see we didn't have no choice
And our hands they are many and we'd be of one voice
We've come all the way from Wigan to get up and state
Our case for survival before it's too late

The main advantage seems to be lack of cobalt. You can burn it and then landfill the ashes.

The cobalt and weight are the main issues with recycling.
Extracting the valuable materials from an EV battery is difficult and expensive. The recycling process typically involves shredding batteries, then breaking them down further with heat or chemicals at dedicated facilities. That part is relatively simple. The harder part is getting dead batteries to those facilities from wherever they met their demise. About 40 percent of the overall cost of recycling, according to one recent study, is transportation. EV battery packs are so massive they need to be shipped by truck (not airplane) in specially designed cases, often across vast distances, to reach centralized recycling facilities. Handling lithium-ion batteries is so demanding that dealerships have chosen to ship an entire 4,000-pound damaged vehicle to Oklahoma City, just so SNT can extract and repair or recycle the 1,000-pound battery inside.

There’s less risk of that for EV battery packs, Raudys says, in part because they are so big and hard to hide. A landfill won’t take them knowingly because of fire risk. A massive pack dumped somewhere is easier to trace back to an owner, or at least to its manufacturer. That will help keep most battery packs on the path to being recycled.

They’re still figuring out the plan for many of the batteries in this warehouse, but Spiers believes that in the end, they’ll be viewed as an opportunity, not waste.
