Overview: Affordable energy storage poised to shift markets In the race to replace cobalt-intensive lithium-ion technologies, a recent international effort has spotlighted a cost-conscious approach to energy storage. The team designed a sodium-ion battery (SIB) storage system built around a P2-type cathode material, Na0.67Mn0.33Ni0.33Fe0.33O2, paired with an unconventional hard carbon anode fabricated from lavender flowers.…
