A battery using cheap, earth-abundant ingredients – and if their findings are correct, we’re looking at a unit perfect for ‘small-scale stationary storage, and ultimately for automotive [uses].’
“…the second-most-abundant metal in the marketplace – and actually the most abundant metal on Earth – is aluminum,” explains Sadoway in an article from MIT News.
“I said, ‘well, let’s just make that a bookend. [The second element is] gonna be aluminum.’”
Apparently, the first element – sulfur – was chosen since it was ‘the cheapest of all the non-metals.’
Pair that with the final one – salt – and you’ve got three items you are pretty much guaranteed to find within a short walk of your house for a lark and a song – and that isn’t all.
Since the three ingredients don’t need to be protected from corrosion, a further cost can be saved in the battery’s production, promoting energy that’s less likely to leak – or, in point of fact, burst into flames.
“Once you get down to near body temperature, it becomes ‘practical’ to make batteries that don’t require special insulation and anticorrosion measures,” Sadoway argues amicably.
In essence, research at MIT has yielded a dirt-cheap battery that doesn’t require babying, isn’t flammable, and uses easy-to-find materials that won’t be a pain to process.
To add the proverbial cherry on the cake, sulfur is also a waste product from petroleum refining – the same process that puts gas in our stations and our current fossil fuel scoots.
With technology presenting new solutions to today’s problems, it’s only a matter of time before one of these findings gets snatched up on a big-volume contract.
