Arbin Instruments 与 Gamry 电位仪集成，用于高达 2 MHz 的高频 EIS
根据Arbin发布的标准规范，将Gamry设备集成到Arbin系统中通常会将设备的原始频率能力从2 MHz限制到100 kHz。然而，在本文中，我们将介绍一种解决方案，该方案可使系统保持完整的2 MHz频率，但需要考虑一些权衡。实现[...]的前提条件
集成了电化学阻抗谱 (EIS) 和 Arbin 充放电通道
引言 电化学阻抗谱（EIS）是评估电池健康状况、内阻、退化机制和电化学行为随时间变化的基石诊断技术。然而，EIS 通常受限于硬件复杂性和每个通道的高成本，在大型电池测试系统中难以扩展。为应对这些挑战，Arbin Instruments 提供了一体化 EIS […]
