What form factor are they manufacturing these in? I'd love some way to swap in a battery for an electric conversion for an old BMW 2002

It's not the best battery type for cars, unless perhaps you are near arctic circle. They are heavy.

Sodium-ion's main advantages are safety, and ultra abundant material source for unlimited batteries, if lithium becomes expensive.

I thought sodium had high charge cycles, as well.

[-] humanspiral@lemmy.ca 2 points 1 week ago

it does. LFP can cycle (slowly) 1 per day for 30 years though. 10 years at full fast charge/discharge. Because of financing/opportunity cost of money, the longer cycle life of Sodium Ion is not a game changer.

Fair points.

Thanks for the considerations. I'll do more research

[-] humanspiral@lemmy.ca 2 points 1 week ago

LFP batteries have huge supply capacity, and have very high value. Amazon, or other sources, are appropriate for a personal project at low cost.

If you have the time or inclination can you tell me if I should wait for solid state batteries or just use the mature LFP. I'm fully aware of the impending tariffs and am already factoring thay into my budget.

LFP batteries are better for EVs/mobillity (with NMC better for ebikes/perfrormance). In some parts of the world, LFP may become more expensive due to extra tariffs, while other parts it can become even cheaper due to high production capacity, and tariffs elsewhere. In the next 1-2 years, LFP is likely cheapest and best option. In 5 years, maybe sodium ion is super cheap.

Thanks so much for taking the time. This is helpful and I'll narrow down my search to LFP

these seem like they'd be great for a UPS, or even home battery and wind/solar

This is the first "big 2" companies doing Sodium Ion. There have been others. This is biggest plant. It is still early days for production. Mass availability will come later.

You can buy the cells, but you have to wire them into batteries yourself

They are good for just that though - some people on YouTube have find it and break down the process

Climate - truthful information about climate, related activism and politics.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
