Interesting. The second web site cites a number of advantages of the sodium-ion battery: > Sodium is 10 times faster to charge than lithium, and safer because of its low operating temperature. The number of recharging cycles is up to 5 times greater than lithium. Another advantage is that sodium is more widely available and accessible on the planet, and its processing has less impact on the environment.
