钠电池新团体标准发布 明年在储能领域或有新突破行业动态

  这意味着,对于主要需求是高能量密度的动力电池来说,钠电池的应用受限。对储能来说◆★◆◆,则不仅需要高能量密度,还需要长循环寿命,所以相较锂电池,钠电池在动力和储能两个领域的应用都有所受限◆■。

  邹嘉逸表示,公司一期的4.5GWh产线月底竣工投产,目前实现了订单和销售。

  应用国际峰会上★■★◆■,业内人士表示,目前钠电池成本最低可做到0.4元/wh,但业内人士对钠电池现阶段产业化进展的重心■★■◆■★,已从成本比较转向低温以及倍率性能要求等细分场景。同时★■◆,与会人士认为明年钠电池在

  中科海钠市场中心总监康利斌在会上表示,钠离子电池做到0★◆◆■★■.6元(/wh)以内,0★★◆◆■★.4元甚至是更低也是可行的。“目前发展规模比较小,成本比较高。”

  但其中,在储能市场,钠电池也是公认的“潜力股■★◆”。聚阴离子则是钠电池运用在储能上的主推正极材料路线★■★。

  上市公司来看,普路通(002768◆■■◆◆.SZ)近期从互动平台透露,公司钠电池订单增速显著。今年8月,在互动平台表示,公司的钠电池18650等型号已实现小规模量产,目前已签订订单大约在40至50万只。9月份则再次表示,公司已率先量产的倍率型钠离子电池,截至目前已签订单超百万只★■★。

  陈建表示,储能包括大储能和中小型的家用储能■■,两种场景要求特性不一样■◆■,在户储上,现在的层状氧化物是能够基本试用◆■★★◆。而对于大储★■,如果没有很长的循环寿命,度电成本降下不来,在储能领域上,可以期待聚阴离子化合物体系的成熟。

  但受今年上半年锂价走低的打击,钠电池的产业化发展落后于预期。鹏辉能源与动力电池研究院助理院长王康曾公开表示:◆■◆★◆“(进度慢)主要的原因其实还是成本,所谓的产业化,本质就是控制成本。现在制约钠电池(产业化)最大的原因是钠电池相对锂电池来说成本太高。◆■”

  据了解,钠电池能量密度较低,目前在100~160Wh/kg,有的甚至还不到100Wh/kg,而锂离子电池基本上是在150~250Wh/kg左右★◆■◆★★。此外,大部分的钠电池的循环寿命在2000~4000次左右,锂电池在4000~6000次左右。

  康利斌表示,“钠电池这一块■★■◆,更重要的价值不是低成本,最核心的价值是供应链的稳健,现在是7、8毛,可预期的未来是往低走的★★,不会高起高落,这是比钠离子电池低成本更有价值的地方■■★★★。■■★◆■★”

  值得注意的是,财联社记者从业内人士处获悉,目前钠电池订单来源的下游应用领域,并非前期行业预期的二轮车领域,而主要源于启停电源◆★、备用电源等更注重倍率、低温性能的领域。

  财联社记者前期获悉,钠电池材料端建成产能不断落地■■◆■,已有较大量级订单★◆◆★★■,有材料端、电池端企业反映产能建设不足,订单难交付。

  中比技术总监胡铭昌在会上表示★■■,今年公司与中科海钠、华宝新能(301327.SZ)合作,量产的产品已陆续做了一些认证以及早期销售,预计2024年将逐步上量,进入整个产品生命周期。

  陈建表示,目前已经有5款车上了3C目录,已小批量进行一些投入■◆■■◆,明年也有更多的车型推出,并且量产线已经全部调通。■◆◆“所以在小动力里面,我们的进展比较顺利的。”

  华宇新能源动力电池研究院院长陈建表示,公司已推出第一代钠离子电池极钠1号的产品,并且目前已在两轮车上小批量的应用。据悉■■◆★◆◆,华宇由雅迪科技集团有限公司全资控股■◆◆。

  虽然钠电池降本进展一直在推进◆■,价格仍未能与磷酸铁匹敌。财联社记者从业内人士处获悉,伴随着锂价亦持续下滑至13万元/吨左右,以及产能结构性过剩导致的激烈竞争,铁锂电池报价仍低于钠电池。

  近期,由与物理电源行业协会指导的《钠离子电池通用规范》(下称■◆★◆★“钠电池规范■★★★■”)团体标准正式发布,规范涵盖三个应用领域,第一是电动汽车,第二是小动力与轻型动力,第三是。

  储能应用方面,因成本与循环性能尚未能与锂电池抗衡,钠离子电池在储能的应用处于比较前期的状态◆■。

  江苏传艺钠电科技副总经理邹嘉逸表示,目前钠离子电池的制造成本约是0◆■■◆■★.45-0.5元/wh■◆■◆■,预计在规模效应以及产业链逐步完善的情况下,成本有望进一步的压缩。

  陈建表示,目前聚阴离子化合物的体系低温的性能很好,在零下20度可以放出90%电量。“我觉得大储的聚阴离子化合物的体系明年逐步有厂家进入小批量的量产■★◆★◆。”

  但从业内人士对钠电池现阶段产业化进展的重心◆■◆,已从成本比较转向运用场景的分化上,即钠电池的低温以及倍率性能显著◆★■。

  据了解,在与物理电源行业协会指导下◆■■◆,动力电池应用分会牵头,联合领域具代表性的电池制造企业■★■■◆◆、上下游供应商等38家相关企业和研究单位◆◆■★◆★,成立标准工作组,制定并发布钠电池规范团体标准★■★■★。

  截至今年12月份的节点,在第八届动力电池应用国际峰会钠电池分论坛上★■★■◆,业内人士最新披露钠电池成本相较上半年进一步压缩。

  今年以来,钠电池产业链各环节量产产能均有不同程度落地,钠电应用项目也取得一些突破性进展■★■◆◆◆,不断推动加速迈向规模化应用■★。
