Abstract: Cost-effective sodium-ion batteries (SIBs) are an important complementary technology to lithium-ion batteries for large-scale energy storage. O3-type layered oxides are promising cathode materials for sodium-ion batteries, but their development is constrained by slow Na+ transfer… read more here.
