Sodium batteries are one of the most exciting things about electric cars for the next few years. And not because they have excellent benefits but because they are very inexpensive. This is the tech that will be in the new cheap electric cars. The main companies that make batteries, CATL and BYD, have already said they are ready to ship, but Svolt just joined the "party." They already have their first sodium-ion battery ready, and its energy density is 100 Wh/kg (Watt-hour per kilogram).
The electric car industry is looking at solid-state batteries and sodium batteries as two critical technologies for the future of transportation. The first will last longer and have better charging times than current lithium-ion batteries. It will also have more power. The sodium batteries, however, are much cheaper than the first type. This technology is much more critical to the general public because it will make it possible for cheap electric cars to be on the market, unlike the options that are being proposed right now. The company Svolt Energy just announced that their prototype first-generation sodium-ion battery with an energy density of 100 Wh/kg is now finished. The company director, Jiang Weijun, said this, and he is also thinking about his plans for this technology.
