Story summary

Gan et al. report a pitch-starch derived hard carbon for sodium-ion batteries, improving initial coulombic efficiency and cycling stability for practical applications.
Zhao et al. report a Ni3Se4/C architecture achieving ultrahigh lithium storage rates, while revealing sodium-ion transport limitations.
Both studies stress sustainable materials and signal potential implications for electric vehicles and renewable energy systems.

History

Historical Context

The development of sodium-ion batteries began in the 1970s but waned in the 1990s as lithium-ion technology gained dominance. Renewed interest emerged in the early 2010s due to rising lithium costs, leading to significant advancements. By 2023, companies like CATL and HiNa were commercializing sodium-ion batteries, which promise lower costs and reduced reliance on lithium, enhancing sustainability in energy storage.
