We need this tech NOW! Some #LithiumIon alternatives discussed are #SodiumIonBatteries, #HydrogenFuelCells and #AqueousMagnesiumBatteries (which I'm just learning about).

6 alternatives to lithium-ion batteries: What's the future of energy storage?

The future of battery tech looks bright, but we might have to wait a while.

"Li-on batteries require environmentally destructive #mining practices for metals such as #lithium, #cobalt, and #nickel. Moreover, a large amount of these metal resources are located in developing countries like the Democratic Republic of Congo [#DRC]. Ethical mining practices haven’t been established in these areas yet, meaning Li-on production contributes significantly to greenhouse gas emissions."

@DoomsdaysCW Years ago, when I was doing my final year studies and getting some industrial experience, I was in the electric vehicle game.

I was working for a small organisation that was trying to build an electric harvester platform. This was out at Laidley in the Lockyer Valley in a place leased from Mulgowie Farming Company.

I had a task to try and source some batteries for this platform… the platform ran on 48V, the motors were extra-low-voltage DC as it meant none of us needed an electrician's ticket to work on it. Trade-off being the cables supplying the 20kW motors were massive, as thick as one's thumb because the current was enormous. 400A.

Lead acid batteries really don't like that sort of treatment. My manager was keen on a Swiss technology called the "Zebra" battery. It was a type of molten-salt battery.

Well… I looked around, yes, I could find press releases about it… but nowhere could I find a supplier. In the end I found a supplier in WA that did electric vehicle parts, they had LiFePO₄ prismatic cells for a reasonable price and the BMS to go with them. So we went LiFePO₄ and forgot all about molten-salt batteries.
