国家对钠离子电池有哪些扶持政策？

What national supporting policies are available for sodium-ion batteries?

国内从顶层双碳战略、能源安全、产业规划、财政补贴、标准研发五大维度出台系列钠离子电池扶持政策，推动技术迭代与规模化产业落地。顶层战略层面：《新型电力系统发展蓝皮书》《“双碳” 目标顶层设计》明确提出发展多元化储能技术，将钠离子电池列为低成本新型储能重点技术路线；《能源资源安全保障规划》强调降低锂资源对外依存度，鼓励钠基储能产业化突破。产业规划政策：工信部《储能产业高质量发展行动计划（2025-2027）》单独列明支持钠离子电池材料、电芯产线建设，鼓励低速交通、户储场景示范应用；多地省级工信、发改出台专项产业扶持，新建钠电池产线给予固定资产投资补贴、税收三免三减半优惠。财政与示范项目：国家能源局持续下达新型储能示范项目补贴，电网侧、乡村户储钠电池项目优先入库；科技部重点研发计划设立钠离子电池专项课题，资助正负极、电解液基础材料攻关；地方政府配套储能示范电站建设资金，采购钠储能系统给予设备采购补贴。标准体系扶持：国家标准化管理委员会、工信部加速钠电池国标立项，出台电芯、PACK、安全测试全套标准，给予标准制定单位研发经费支持。进出口扶持：钠电池储能设备出口享受 13% 增值税出口退税，中欧、东盟跨境新能源装备通关简化绿色通道。配套乡村振兴政策：农村分布式光伏配套钠储能纳入乡村能源改造补贴范围。政策导向清晰，全方位从研发、建厂、示范、出口、税收降低钠电池产业发展门槛，加速国产钠电池商业化普及，保障国内能源自主可控。

China has issued a series of supporting policies for sodium-ion batteries covering top-level dual-carbon strategy, energy security, industrial planning, fiscal subsidies and standard R&D to drive technological iteration and large-scale industrial implementation. Top-level strategy: The Blue Book for New Power System Development and top-level dual-carbon design clearly list diversified energy storage technologies and regard sodium-ion batteries as a key low-cost new storage route. The Energy Resource Security Plan stresses reducing lithium import dependence and encourages industrial breakthroughs of sodium-based storage. Industrial planning: MIIT’s High-quality Energy Storage Development Action Plan (2025-2027) supports construction of sodium cell & material lines and demonstration in low-speed transport & household storage. Provincial industry & development authorities release special industrial incentives including fixed asset investment subsidies and three-year tax exemptions for new sodium production lines. Fiscal & demonstration support: NEA issues continuous subsidies for new storage demonstration projects with priority admission of grid and rural sodium storage; MOST sets special key R&D projects to fund cathode/anode & electrolyte material breakthroughs; local governments allocate funds for demonstration power stations and offer equipment purchase subsidies. Standard support: SAC and MIIT accelerate national standard establishment for cells, PACK and safety testing with R&D funding for drafting institutions. Import & export incentives: 13% VAT export rebates apply to sodium storage equipment, with simplified customs green channels for China-EU and ASEAN new energy goods. Rural revitalization matching policies include residential PV sodium storage in rural energy renovation subsidies. The policy framework comprehensively lowers industrial barriers via R&D, factory construction, demonstration, export and taxation support, accelerates domestic sodium commercialization and guarantees independent energy security.
