Ever since climate deniers lost the argument on basic science, they have spent their time sneering at every new sustainable initiative. Targets of their scorn include solar panels, windfarms and of course batteries, which will never be big enough/stable enough/environmentally friendly enough for their liking. That last bit always makes us laugh; so should their reaction to this new development in sodium-ion batteries as explained by Nature Briefing in this excellent piece called The Battery that could change everything
| Sodium-ion batteries promise to be cheaper, safer and more environmentally friendly than the lithium-ion cells that currently dominate technologies such as electric cars. And the sea-change could finally be here: CATL — the world’s largest battery producer — has announced that it will start mass-producing sodium-ion batteries by the end of the year. A swell of interest from battery makers and researchers has helped to solve longstanding challenges, such as a lack of durability. Nature | 10 min read |
There’s so much to like here that we don’t know where to begin. Sodium is so much more abundant and easier to mine than lithium: so that’s the environmental and cost bases covered in a nutshell. Sodium batteries[1] will be safer, and better in cold weather than their lithium-ion cousins that we use so much now, Yes, they will be heavier and have lower energy densities. But that will not matter in most applications such as short-range cars, domestic and industrial power storage, the delivery market and back up of all kinds. Lithium will still probably win out in areas of high performance like luxury long distance EVs and aircraft propulsion. But- energy technology is not about final winners, it’s about horses for courses.
And there’s a final, Devil-whispers-in-our-ear warning for fans of Geopolitics. Note once again how the initiative in all this is coming from China. One hundred years ago, America was the home of all that was new. Now it seems determined to stick to the old methods of fossil fuels as if the blissful moment of its perfection can somehow be preserved forever. Not a happy choice.
