Rechargeable Lithium-ion (Li-ion) batteries are an essential part of automotive electrification, mobile communications, and consumer electronics. It is essential that Li-ion batteries operate reliably and safely, which requires real-time temperature monitoring. The current battery thermal sensing focuses on sensors placed at strategic locations along battery surfaces, which lack the spatial resolution to provide a complete thermal map. In situ temperature sensing inside each cell is therefore of paramount importance for the safety and efficiency of batteries. Such a technological solution is highly sought after to reduce failure and improve safety and quantum sensing technology can provide an ideal solution because of its size, ultrafast response, and resolution. This international quantum catalyst (quantum sensing and quantum materials) grant aims to initiate an international partnership to explore the viability of graphene-based quantum dot sensors in Li-ion batteries for high resolution and high accuracy temperature sensing. Graphene quantum dots (GQDs) are single or few layers of graphene that have unique and fascinating physical properties such as strong quantum confinement and edge-dependent electrical properties because the electronic transport is confined in all three spatial dimensions. Modifying their size, shape, and defects allows researchers to tailor the GQDs electrical and thermal properties for specific sensing applications. By optimizing their properties, we propose to develop a new class of GQD-based flexible, high-resolution, and highly precise temperature sensors that can be conformally fitted inside battery cells. The outcome will benefit Canadian quantum academics and industries through the comprehensive training of highly qualified personnel in the field of quantum science, materials, and quantum sensing thus contributing to strengthening Canadian skills in quantum technology. The proposed innovations and unique training in quantum sensors are expected to lay a solid foundation for the Canadian team to seek further funding to create a breakthrough in sensing technology and will thus directly assist the Canadian quantum academic and industry.

可充电锂离子（锂离子）电池是汽车电气化，移动通信和消费电子产品的重要组成部分。锂离子电池必须可靠，安全地运行，这是必要的，这需要实时温度监测。当前的电池热感应集中在沿电池表面的战略位置放置的传感器，这些传感器缺乏空间分辨率，无法提供完整的热图。因此，对于电池的安全性和效率，每个单元内的原位温度传感至关重要。这种技术解决方案受到了极大的追求，以减少故障并改善安全性，量子传感技术可以提供理想的解决方案，因为它的尺寸，超快响应和解决方案。这种国际量子催化剂（量子传感和量子材料）旨在启动国际合作伙伴关系，以探索锂离子电池中基于石墨烯的量子点传感器的可行性，以进行高分辨率和高精度温度感测。石墨烯量子点（GQD）是单层或几层石墨烯，具有独特而引人入胜的物理特性，例如强量子限制和边缘依赖性电性能，因为电子传输限制在所有三个空间维度中。修改其大小，形状和缺陷，使研究人员可以为特定的感应应用定制GQD的电气和热性能。通过优化其性能，我们建议开发一类新的基于GQD的柔性，高分辨率和高度精确的温度传感器，这些温度传感器可以在电池电池内进行合成。结果将通过对量子科学，材料和量子感知领域的高素质人员进行全面培训，从而使加拿大量子学者和行业受益，从而有助于增强加拿大量子技术的技能。拟议的量子传感器的创新和独特的培训预计将为加拿大团队寻求进一步的资金以创造传感技术的突破，从而为加拿大量子学术和行业提供突破。
