目前“最先进”的锂离子电池监测和控制技术依赖于全电池电位测量和偶尔的表面温度测量。然而，锂离子电池是复杂的多层器件，因此这些技术具有较差的分辨率，限制了适用性。在这项工作中，我们开发了放置在电池内的混合热电化学传感阵列。该阵列在制造过程中集成到A5袋电池中，用于创建与阳极和阴极电化学数据并行的热图。传感器阵列可以适应各种电池格式和化学性质，并安装到商业或其他工业相关的电池中，将增强的热学和电化学诊断能力整合到标准电池中。
Current "state-of-the-art" monitoring and control techniques for lithium-ion cells rely on full-cell potential measurement and occasional surface temperature measurements. However, Li-ion cells are complex multi-layer devices and as such these techniques have poor resolution, limiting applicability. In this work we develop hybrid thermo-electrochemical sensing arrays placed within the cell. The arrays are integrated into A5 pouch cells during manufacture and are used to create thermal maps in parallel with anode and cathode electrochemical data. The sensor array can be adapted to a range of cell formats and chemistries and installed into commercial or other industrially relevant cells, incorporating enhanced thermal and electrochemical diagnostic capability into a standard cell build.
