论文摘要
固态电池技术是出于渴望以安全有效的方式提供灵活的电源存储的愿望。批量生产设施中越来越广泛地使用电池,凸显了需要快速敏感的诊断来识别电池缺陷的需求。我们证明了使用原子磁力测定法来测量微型固态电池电池周围的磁场。这些字段编码有关电池制造缺陷,充电状态,杂质的信息,或者可以为老化过程提供重要的见解。与基于鱿鱼的磁力测定法相比,原子磁力计的可用性突出了电池质量控制和表征技术的低成本,便携式和灵活实现的可能性。
Solid state battery technology is motivated by the desire to deliver flexible power storage in a safe and efficient manner. The increasingly widespread use of batteries from mass-production facilities highlights the need for a rapid and sensitive diagnostic for identifying battery defects. We demonstrate the use of atomic magnetometry to measure the magnetic fields around miniature solid-state battery cells. These fields encode information about battery manufacturing defects, state of charge, impurities, or can provide important insights into ageing processes. Compared with SQUID-based magnetometry, the availability of atomic magnetometers, however, highlights the possibility for a low-cost, portable, and flexible implementation of battery quality-control and characterization technology.
