South Korea’s battery industry roadmap sets a 2030 commercialization target for sodium-ion batteries, aimed at energy storage and lower-cost electric vehicles. The government also proposes coordinated industry projects and a production tax credit from 2027, but has not specified how much planned funding will go to sodium-ion technology.
South Korea has set a 2030 commercialization target for sodium-ion batteries, placing the technology among its priorities for energy storage systems and lower-cost electric vehicles. The roadmap, released September 22, also sets energy-density targets for 2027 and 2030 as the government seeks to strengthen domestic battery makers’ position in markets where Chinese suppliers are dominant.
The government’s Battery Industry Technology Roadmap calls for sodium-ion batteries to reach an energy density of 160 watt-hours per kilogram by 2027 and 220 Wh/kg by 2030. It names energy storage and lower-cost EVs as intended markets, where lower cost can matter more than the high energy density sought for premium vehicles. The roadmap sets the goals; it does not confirm that the targets have already been achieved or that products will be commercially available on schedule.
South Korea’s three major cell makers — LG Energy Solution, Samsung SDI and SK On — were involved alongside major materials suppliers, according to the report. The government proposes cooperation on areas it considers non-competitive, including battery dimensions and component specifications. Another proposed model would have materials companies develop products to agreed price and performance targets, followed by cell-maker testing and purchasing. Projects are scheduled to begin in 2027.
The roadmap also proposes a production tax credit from 2027, battery-recycling measures and a system to send EV battery-management data back to cell and materials developers. It outlines a research program costing about KRW 400 billion from 2027 to 2031, or just under $300 million. The ministry said companies intend to invest around KRW 8 trillion, reported as about $8 billion, in research and production facilities between 2026 and 2030. It did not specify how much of either amount is for sodium-ion batteries.
A Route Into Cost-Sensitive Markets
The shift reflects a competitive gap South Korea is trying to address. Lithium iron phosphate batteries account for around 90% of global battery-storage deployments, according to the International Energy Agency, while Chinese companies dominate LFP cell and materials production. South Korean manufacturers have generally focused more on high-nickel lithium-ion batteries for electric vehicles.
Sodium-ion could give Korean suppliers another way to compete in stationary storage and less expensive EVs, where cost can weigh more heavily than maximum range. But the technology is not yet a straightforward cost advantage: the source report says sodium-ion batteries currently remain more expensive. Whether the roadmap helps Korean companies close the gap depends on their ability to meet its performance and cost goals and move from development to production.
The government described its wider ambition as retaking global battery-market leadership through “selection and focus.” That is an official aim, rather than a result established by the roadmap. Its proposals may coordinate research and supply-chain work, but their effect on production costs, market share and sales remains to be seen.
Korea’s Battery Strategy Broadens
The roadmap covers more than sodium-ion technology. It also sets a separate path for all-solid-state batteries, with a prototype target for 2027 and commercialization targeted for 2030. The government’s roadmap sets a 2028 energy-density target of 400 Wh/kg for solid-state batteries and identifies high-performance EVs, robots, drones and urban air mobility as potential markets.
The two technologies address different parts of the battery market. Sodium-ion is positioned for uses where affordability is important; solid-state batteries are aimed at demanding applications that seek high performance. The roadmap thus combines a bid to enter cost-sensitive segments with investment in technologies intended for higher-performance products.
China’s CATL released a sodium-ion battery with an energy density of 160 Wh/kg in 2021 and has since upgraded the technology, according to the report. That prior benchmark provides context for South Korea’s 2027 target; it does not by itself show whether Korean products will match CATL’s current performance or compete on cost.

Funding and Delivery Remain Open
The roadmap does not allocate a specific share of its KRW 400 billion research program or the companies’ planned KRW 8 trillion investment to sodium-ion work. It also does not give the proposed production tax credit’s value or detailed eligibility rules. Those details will affect how much support reaches sodium-ion development and manufacturing.
It remains unclear whether manufacturers can meet the energy-density milestones while lowering costs enough to compete in storage and lower-priced EVs. The roadmap sets targets, but provides no confirmed commercial production volumes, customer commitments or market-share projections. The ministry’s “world first” description of the 2027 solid-state prototype also lacks a stated basis for comparison.
Projects Start in 2027
The next scheduled step is for the proposed collaboration projects to begin in 2027, alongside the proposed production tax credit. Progress toward the first sodium-ion performance milestone — 160 Wh/kg in 2027 — will offer an early measure of whether the roadmap is moving from targets to technical results.
Further details on funding allocations, tax-credit design and recycling measures would clarify how the government plans to support production. The longer-term test will be whether companies can reach the 2030 commercialization target and supply products that compete on cost and performance. The roadmap sets that objective, but does not confirm the timing or scale of future commercial deployment.
Key Questions
What has South Korea announced?
South Korea’s September 22 battery roadmap sets a 2030 commercialization target for sodium-ion batteries and performance milestones for 2027 and 2030.
Which markets are sodium-ion batteries intended to serve?
The roadmap identifies energy storage systems and lower-cost electric vehicles as intended markets for sodium-ion batteries.
How much funding is set aside for sodium-ion batteries?
The roadmap proposes a research program worth about KRW 400 billion for 2027–2031, but the ministry has not said how much is specifically for sodium-ion. It also reported planned company investment of around KRW 8 trillion for research and production facilities from 2026 to 2030, without a sodium-ion allocation.
Why is South Korea focusing on sodium-ion batteries?
The strategy could help Korean suppliers pursue battery-storage and lower-cost EV markets, where Chinese companies have a strong position in lithium iron phosphate batteries. Sodium-ion batteries remain more expensive today, according to the source report, so their competitive prospects are not yet settled.
What other battery technology is in the roadmap?
The roadmap also targets all-solid-state batteries, with a 2027 prototype target, a 2028 target of 400 Wh/kg and commercialization targeted for 2030.
