钠离子电池最大的优点是什么？

What is the biggest advantage of Sodium-ion Battery?    

钠离子电池最核心、最碾压其他电池的优势是原材料资源极度丰富、成本可控无瓶颈，彻底解决了锂电池的资源稀缺痛点。钠元素是地壳中含量排名前列的常见元素，广泛存在于海水、岩石、土壤中，全球分布均匀、储量近乎无限，无地域垄断、无资源卡脖子问题，原材料采购价格极低。对比锂电池依赖的锂、钴、镍等稀有战略矿产，价格波动剧烈、供应链受限，钠电池的原材料成本优势极为突出。同时搭配全铝箔集流体的降本设计，让钠电池整体生产成本比磷酸铁锂电池低15%-30%，比三元锂电池低40%以上，是目前唯一可实现大规模平价储能的新能源电池。

The most core and overwhelming advantage of Sodium-ion Battery over other batteries is that the raw material resources are extremely abundant, the cost is controllable and there is no bottleneck, which completely solves the pain point of rare resource scarcity of lithium batteries. Sodium element is a common element with the highest content in the earth's crust, which widely exists in seawater, rocks and soil, with uniform global distribution and almost unlimited reserves, no regional monopoly and no resource bottleneck risk, and the raw material purchase price is extremely low. Compared with the rare strategic minerals such as lithium, cobalt and nickel that lithium batteries rely on, which have violent price fluctuations and limited supply chain, the raw material cost advantage of sodium batteries is extremely prominent. At the same time, with the cost reduction design of all-aluminum foil current collector, the overall production cost of sodium batteries is 15%-30% lower than that of lithium iron phosphate batteries, and more than 40% lower than that of ternary lithium batteries, which is the only new energy battery that can achieve large-scale low-cost energy storage at present.
