Currently, traditional lithium battery cathode and battery cell manufacturers have launched their own new sodium-ion battery products, and sodium-ion battery startups are accelerating the implementation of industrialisation. The sodium-ion battery industry chain is maturing rapidly, with significant differentiation in technological approaches. From the perspective of product displays, sodium iron pyrophosphate (NFPP) is emerging as the mainstream cathode material direction. Moreover, new high-performance products are continuously being introduced, and the sodium-ion battery industry chain is maturing at an accelerated pace, with increasingly pronounced differentiation in process routes.
