In operando calibration of printed battery management sensors

先进材料开发（AMD有限公司）正在将利用纳米材料技术的创新可打印传感器工业化，用于组件上的结构健康监测应用，包括电池管理系统。在该项目中，在国家物理实验室（NPL）的协助下，我们将全面验证和验证一种新型的可打印离子传感器，该传感器可以简单地同时监测电池应变和温度。这些传感器特别适用于锂离子电池，尤其是使用高能量密度硅阳极技术的电池。它们在充放电循环过程中会发生显著的膨胀，因此必须仔细监测，以确保安全有效的操作，特别是在运输和航空应用中。该研究将涉及应变和温度的仔细测量，以验证和验证典型充电和放电速率的传感器，这些速率模拟了运输或电动工具应用中通常遇到的重复高功率使用的操作特性。能够直接打印到电池袋上将允许分析任何未来的封装电池技术。这反过来又将允许对新开发产品进行进一步测试，以确保它们安全地介绍给消费者。

Advanced Material Development (AMD Ltd.) is industrialising innovative printable sensors utilising nanomaterial technologies for on-component structural health monitoring applications, including battery management systems. Within the project and with the assistance of National Physical Laboratory (NPL), we will fully characterise and validate a novel printable ionic sensor that allows for simple and simultaneous battery strain and temperature monitoring. These sensors are particularly suited to Lithium-ion batteries, especially where high energy density silicon anode-based technologies are used. They undergo significant expansion during charge-discharge cycling so must be carefully monitored to ensure safe and efficient operation especially when used in transport and aviation applications. The study will involve careful measurement of strain and temperature to both characterise and validate sensors for typical charging and discharging rates which mimic operational characteristics for repeated high-power use typically encountered in transport or power tool applications. Being able to directly print onto battery pouches will allow for analysis of any future encapsulated battery technologies. This in turn will allow for further testing of new developments to ensure they are safely introduced to consumers.
