China’s new five-year plan targets large-scale all-solid-state battery use by 2030, while South Korea unveils a massive R&D roadmap to counter Chinese dominance. However, critics argue Korea’s current tax credits fail to support loss-making firms, risking a widening technological gap.
GM is pursuing domestically sourced, next-generation battery cells—starting with sodium-ion for energy storage—with a plan to commercialize by 2029 and reduce U.S. dependence on Chinese materials, while Ford faces scrutiny over its China ties.
Global demand for batteries is surging due to EVs and renewable storage, but lithium-ion remains dominant while two near-term paths emerge: affordable sodium-ion batteries for budget EVs and grid storage, and high-end solid-state cells for longer-range luxury EVs; researchers are exploring many chemistries and architectures to speed charging and improve safety, with commercialization of solid-state anticipated by the late 2020s to 2030s and lithium-ion likely to stay the majority through 2035.
Researchers at Tokyo University of Science found that using hard carbon as the anode enables high sodium storage and faster sodiation, potentially matching fast charging of lithium ion batteries and boosting energy density. Sodium ion batteries offer environmental and supply chain advantages, including cheaper production and safer shipping, with growing use in vehicles. However they still lag lithium ion in energy density and face challenges to sustain fast charging due to ion traffic jams, so lithium ion remains dominant for now while sodium ion technology continues to advance.
Sodium-ion batteries are emerging as a potential alternative to lithium-ion batteries, which have dominated the market for decades. This shift is driven by concerns over the environmental and social impacts of lithium mining and processing.
