Lithium-ion batteries (LIBs) are pivotal energy devices in our daily lives, yet ensuring the quality and health of LIBs throughout their manufacturing and application processes remains a significant challenge. Here we propose a universal “color-coding” technique to indicate the health of LIBs, by which specific property characteristic and evolution inside LIBs can be unfolded. By defining the standard color coding for the entire manufacturing and application processes of LIBs, we show the change in material characteristics during various processes can be described by variations in standard color coding. Therefore, by establishing a universal color-property database, the proposed “color-coding” method has potential to be used as a practical tool to ensure the quality of materials and healthy operation of batteries.

对锂离子电池的健康状况进行颜色编码实时检测


锂离子电池 （LIB） 是我们日常生活中的关键能源设备，但确保锂离子电池在整个制造和应用过程中的质量和健康仍然是一项重大挑战。在这里，我们提出了一种通用的 “颜色编码 ”技术来指示 LIBS 的健康状况，通过该技术可以揭示 LIBS 内部的特定特性、特征和进化。通过定义 LIBS 整个制造和应用过程的标准颜色编码，我们表明各种过程中材料特性的变化可以用标准颜色编码的变化来描述。因此，通过建立一个通用的颜色特性数据库，所提出的“颜色编码”方法有可能被用作确保材料质量和电池健康运行的实用工具。
