sodium battery

More correctly this is the sodium-ion battery contrasted with the lithium-ion battery.  We all know we want better batteries and sodium may provide at least one answer. Sodium is cheap and plentiful whereas lithium is not so easy to find. The sodium battery therefore is cheaper, and on top of that it charges faster and is safer, and functions better at higher and lower temperatures than the lithium battery. Its downside is a lower power output but it is early days. Now a Chinese company is producing sodium batteries for electric cars. The sodium car could be a major change in the EV world.
