Sodium ion batteries, page-55

Conclusion: Performance takes priority
My conclusion is relatively pessimistic.
I don't think sodium-ion batteries can replace lithium-ion batteries in electric cars alone or storage facilities for replacing lead-acid batteries. At most, it is a means of reducing cost, and it can be used in conjunction with lithium-ion batteries to reduce the cost of the entire battery pack.An important point of view is that the core of the competition between power batteries must be performance rather than cost. It must be performance first and then cost reduction, rather than reducing cost first and then improving performance. Giving up performance just for cost is putting the cart before the horse.
