Another potential use for sodium ion battery tech is in grid-scale storage systems, like those mentioned here;

rnz.co.nz/news/national/556884

(#HatTip to @norightturnnz for the link)

I have no idea what chemicals are currently used when building such systems. But if they're lithium ion they'll be stupidly expensive to build, and if they're lead acid - which seems more likely - they'll need replacing much sooner.

A year ago I posted about some folks I know with an off-grid system powered by a water wheel and solar panels, who were awaiting delivery of some of the first commercially available sodium ion batteries. Well, they've had them in for a year now and they're totally sold on them. Although the real test will be how they're performing in 5-10 years time.

Blimey - according to thedriven.io/2024/01/25/worlds the world's largest battery manufacturer, China's CATL will be halving the price of its Lithium Iron Phosphate batteries this year. "This means the price of an average 60 kWh battery pack will have dropped from $US6,776.00 to just $3,388.00 in just 12 months, saving EV manufacturers over $3,000 per vehicle."

Our #BEV (MG4 Excite) has a 51kWh pack... So we could replace a future (post 7yr warranty) failed pack for well under US$3k... #BatteryTech

I am in constant amazement at how cheap battery tech is getting. Particularly on the used and second hand markets.

This unused 46 kWh pack uses more stable, (less explode-y) lithium iron phosphate (LiFePO4) chemistry, and it's under $4k.

46kWh is enough to power our home for about two days.

Just a few years ago I spent $1.5k for about 2 kWh worth of used pouch cells.

unused power pack containing 52 3.2 vold 280 amp hour LiFePo4 cells. Comes out to under $100 per kilowatt hour.

For #travel - I'm intrigued - 100Wh in such a small package looks amazing.

"It has a 99Wh capacity and charges through 100W Dual PD Outputs and a USB-A output. It can be charged in three ways, including via solar, DC input, or a car. The Explorer 100 Plus features a durable LiFePO4 battery with a self-developed BMS for added protection, and it is compliant with UN 38.3 shipping standards for lithium batteries, making it travel-friendly"
