新能源专利分享—宁德时代公开电池单体、电池及用电装置2023-03-07 10:35·新能源专利洞析宁德时代新能源科技股份有限公司成立于2011年，总部位于福建宁德，公司前身为消费锂电池龙头ATL的动力电池事业部，凭借雄厚的锂离子电池技术背景迅速崛起。除此之外，凭借着过硬的电池创新技术，宁德时代自2017年起连续四年获得全球动力电池出货量榜单第一，并先后发布了CTP电池包和钠离子电池技术。2018年6月公司顺利登陆A股创业板在深交所上市。宁德时代是全球领先的锂离子电池提供商，专注于新能源汽车动力电池系统、储能系统的研发、生产和销售，致力于为全球新能源应用提供一流解决方案。（一）专利分布在研发费用方面，公司研发投入不吝成本，通过正向反馈提升业绩。公司研发支出维持高增速，显著领先于国内同行。截至2020年底，公司共有2969项境内专利，348项境外专利和5592名研发人员。在新能源车市场政策驱动向市场驱动的过程中，降本提效诉求增强，技术层面的改善将是公司提升溢价的关键维度。无论是基础的材料开发，还是整体工艺的完善，都需要强研发支出作为支撑。从这一角度看，龙头公司因具备持续的技术积累以及充足的现金流，有望形成正向循环，进一步增厚竞争壁垒。宁德时代专利分布（二）钠离子电池研发除了在传统锂电池领域的布局之外，宁德时代试图探索钠离子电池的市场蓝海，在钠离子电池的研发方面投入了大量资源。宁德时代钠离子电池技术CN115064757A公开电池单体、电池及用电装置摘要本申请提供一种电池单体、电池及用电装置。该电池单体包括壳体和多个电极组件单体，多个电极组件单体沿第一方向并排间隔设置于壳体内，每个电极组件单体包括层叠设置的第一极片、隔离膜和第二极片，相邻的第一极片与第二极片之间具有隔离膜，层叠设置的第一极片、隔离膜和第二极片对折形成两个沿第一方向正对间隔设置的平直区以及连接于两个平直区之间的折弯区。这样，本申请的单个电极组件单体只有一个折弯区，电池单体正置状态下，电极组件单体能够被电解液浸润，有利于减少折弯区因电解液不足而导致发生析锂的几率；且电池单体具有多个电极组件单体，可以缓解仅设计一个电极组件单体存在层叠层数过厚而导致电极组件单体的稳定性低的问题。技术领域[0001]本申请涉及电池技术领域，尤其涉及一种电池单体、电池及用电装置。背景技术[0002]节能减排是汽车产业可持续发展的关键，电动车辆由于其节能环保的优势成为汽车产业可持续发展的重要组成部分。对于电动车辆而言，电池技术又是关乎其发展的一项重要因素。[0003]目前，电池的电极组件主要采用叠片和卷绕两种工艺制成，卷绕式电极通常包括两个平直段和两个弯曲段，两个平直段间隔设置，两个弯曲段分别位于平直段的两端并与两个平直段连接。但是，卷绕式电极的弯曲段容易发生析锂现象，危害电池的安全。第一权利要求:1.一种电池单体，其特征在于，包括：壳体；多个电极组件单体，每个所述电极组件单体包括层叠设置的至少一个第一极片、至少一个隔离膜和至少一个第二极片，所述第一极片的极性与所述第二极片的极性相反，相邻的所述第一极片与所述第二极片之间具有所述隔离膜，层叠设置的至少一个第一极片、至少一个隔离膜和至少一个第二极片具有对折形成的两个沿第一方向正对间隔设置的平直区以及连接于两个所述平直区之间的折弯区；其中，沿所述第一方向，多个所述电极组件单体并排间隔设置于所述壳体内。
