#SodiumIonBatteries offer an alternative to tricky #lithium
Oct 26th 2023
Excerpt: "Fortunately, lithium is not the only game in town. As we report this week, a clutch of firms are making batteries based on sodium, lithium’s elemental cousin. Since sodium’s chemical properties are very similar to those of lithium, it too makes for good batteries. And sodium, which is found in the salt in #seawater, is thousands of times more abundant on Earth than lithium and cheaper to get at. Most of the companies using sodium to make batteries today are also Chinese. But pursuing the technology in the West might be a surer route to energy security than relying heavily on lithium.
"Besides its abundance, sodium has other advantages. The best lithium batteries use #cobalt and #nickel in their electrodes. Nickel, like lithium, is in short supply. #Mining it on land is #EnvironmentallyDestructive. Proposals to grab it from the #seabed instead have caused rows. A good deal of the world’s cobalt, meanwhile, is extracted from small mines in the #DemocraticRepublicOfCongo, where #ChildLabour is common and working conditions are dire. Sodium batteries, by contrast, can use #electrodes built from #iron and #manganese [and wood #lignin], which are plentiful and uncontroversial. Since the chemical components are cheap, a scaled-up industry should be able to produce batteries that cost less than their lithium counterparts.
"Sodium is not a perfect replacement for lithium. It is heavier, meaning sodium batteries will weigh more than lithium ones of an equivalent capacity. That is likely to rule them out in some cases where lightness is paramount. But for other applications, such as #GridStorage or #HomeBatteries, weight is irrelevant. Several Chinese carmakers are even beginning to put sodium batteries in #ElectricVehicles."

The rush to get large home batteries before the federal rebate is restructured has seen many reputable battery installers booked out through to May, when the changes to the Cheaper Home Battery Program come into force. #homebatteries #renewables www.solarquotes.com.au/blog/battery...

Since #SodiumBatteries are rolled out by #China now, which are much more useful in a wide range of temperatures from (-20°C to 60°C) up to (-70°C to 100°C), mega-batteries will replace fossils even faster.
I still advocate for more #homebatteries and #microgrids to stabilize the grid. -

Chris Bowen’s hamfisted messaging today about #HomeBatteries risks a rerun of Labor’s disastrous #PinkBatts fiasco as #solar installers rush to beat his arbitrary May 2026 deadline. #renewables #CostOfLivingCrisis #ClimateCrisis #auspol

Hmmmm. Huge battery pack bought via Alibaba explodes and destroys house. There might be a cautionary tale or two in there. Like 30kWh of energy stored in compact metal boxes of dodgy provenance and mounted right inside your home.

How many #evcharger, #solarinverter, #vehicle and #homebatteries do you recognize?

@ukuku This makes so much sense, with or without #SolarPower, depending on budget.
First of all, the backup #HomeBatteries use old EV batteries, giving them a second life. Then the EV itself now has a second use, as a backup battery.
Finally some competition for the #Powerwall, which seems to enjoy outrageous pricing in the absence of more alternatives.
