Core Viewpoint - Sodium batteries are expected to see increased applications in energy storage and other fields where energy density is not critical due to continuous cost reductions [4][12]. Group 1: Market Trends and Developments - Sodium energy storage previously faced challenges due to high costs, leading to a reduction in project scale and a halt in full-capacity sodium energy storage projects [5]. - Major lithium battery companies are entering the sodium battery market, injecting new energy into the industry, with companies like Rongbai and Longpan ramping up sodium battery material production [5][6]. - By early 2026, several megawatt-level sodium energy storage projects are expected to be operational, including a 100MW/200MWh project in Honghu City and a collaboration between Zhongna Energy and Guodian to develop a similar project in Tieling, Liaoning [7][8]. Group 2: Technological Advancements - Zhongke Haina has successfully integrated sodium-ion battery systems into the power distribution network in Guangxi, showcasing the technology's application in enhancing power quality and stability [9]. - The polycation sodium battery is gaining traction in the energy storage sector due to its long lifespan, low cost, and high safety, gradually surpassing layered oxide batteries in market share [10][11]. Group 3: Cost and Production Insights - The cost of polycation sodium battery materials is projected to drop below 20,000 yuan per ton, with further reductions expected as production scales up [12]. - The cost of sodium battery cells is anticipated to fall below 0.4 yuan/Wh, enhancing their competitiveness in energy storage applications [12]. - By 2025, sodium battery shipments for energy storage are expected to exceed 50% of the market, becoming a key growth driver for the industry [13].

一个产业样本。 作者 I 吴琼 报道 I 投资界PEdaily 一个个钠电企业开始来到自贡。 今天（1 2月1 8日）上午，自贡高新区板仓工业园区内，珈钠年产1 0万吨钠电材料项目生产线正式投产。追溯起来，珈钠能源自去年底 决心落地自贡，短短一年时间内相继完成项目签约、开工、建成、投产。据悉，深圳珈钠能源1 0万吨/年聚阴离子正极材料生产基地一 期项目达产后，年产量2万吨，实现产值7亿元。全面建成达产后预计可实现年销售收入约3 5亿元、年税收约1 . 7 5亿元。 如此高效背后，正是自贡招商模式的一缕写照。据自贡市相关工作人员介绍，为加快项目落地投产，自贡通过审批改革、设立专项基 金、政策支持等服务举措，破解产业项目开工慢难题，从而使珈钠项目实现"拿地即开工"。 类似的案例，自贡至今已成功引入兴储世纪、深圳长盈、江苏天钧等企业，签约钠电储能项目3 1个。当越来越多项目汇聚于此，一个自 贡千亿级新能源产业故事也徐徐拉开序幕。 一抹缩影 武大教授带队落地自贡 其实早在一年前，自贡招商团队就已经注意到珈钠能源。 彼时，自贡正全力布局钠电产业新赛道，在招商引资、项目建设、政务服务等方面实施系列措施，希冀通过招引一批新 ...
