CATL’s Reinforced Sodium Battery Changes Everything
23rd December 2025
Ziroth runs a YouTube channel that keeps an eye on technological advances. Nothing needs technological advance more than the energy storage area.
The reason gasoline is so pervasive is that it is very energy-dense, pretty stable as commonly stored, reasonably safe (movie car gas tank explosions to the contrary notwithstanding—it’s actually very difficult to get liquid gas to explode), and we’ve got an extensive industry devoted to getting high quality stuff to consumers quickly and cheaply.
The use of electricity for transportation is hampered by the fact that electrons can’t just be stuffed into a tank for later use. You either have to generate them on-site (which is how hybrids operate) or store them chemically (via batteries). Energy storage for electrons is neither cheap nor efficient. So I keep an eye out for discoveries that will make our lives easier in this respect.
