The price reduction of lithium carbonate and the return of cost-effectiveness of lithium batteries: "The decline in lithium prices continues to be beneficial for downstream consumers, while the price advantage of sodium ion batteries decreases, further reducing their cost-effectiveness." Industry insiders have stated that in the long run, power batteries will present a diversified technological route, risk factors will be flattened and stabilized, and the value of production capacity will gradually emerge in the future. Some battery manufacturers also stated, "In the long run, there is still room for development of sodium ion batteries
