In lithium battery cell research, developers create various samples corresponding to different electrical research purposes, such as fine-tuning material ratios, verifying degradation characteristics, and simulating end-use applications. These samples may include coin-type half-cells, which are low-cost and can be quickly assembled for preliminary analysis, or small pouch battery cells, which more closely resemble actual applications and can more accurately reflect battery degradation characteristics. Different types of batteries and testing scenarios require an array of capabilities from battery charge/discharge test stations. For example: (1) the specified voltage range must accommodate both high-potential tests for positive electrodes and low-potential tests for negative electrodes, (2) current measurement should ensure accurate and low-noise readings from ampere (A) outputs for coin batteries, and (3) a multi-channel fixture system should enable quick loading and unloading to improve verification efficiency while being compatible with different types of batteries. In other words, reliable testing, convenient changeover, and high flexibility are core requirements for such applications.

Building upon its acclaimed 17010 series of battery test systems, Chroma has developed the 17216M-10-6, a specialized model designed for battery cell lab units. It features a wide voltage output range of -5V to 10V to accommodate the analytical needs of different types of batteries, and a current range of 6A to 0.1µA. The model's four testing ranges—6A, 20mA, 6mA, and 200µA—make it a perfect fit for coin-type batteries and small pouch batteries. With a maximum accuracy of 0.015% F.S., the equipment ensures reliable testing results. In the constant voltage charge-discharge testing mode, the device automatically switches output ranges as the current decreases, significantly reducing error of control and noise.

As a complement to the 17216M-10-6, Chroma has developed the "Coin/Pouch Cell Two-in-One Test Fixture". This versatile testing tool is specifically designed to meet the high levels of flexibility and convenience required by various applications. It allows for easy testing of both coin-type and pouch-type batteries, significantly reducing loading and unloading time while maintaining safe and stable testing conditions. The fixture offers several key benefits:

1. Space-saving: The vertical rack design significantly reduces the system's footprint, with one set of racks meeting the testing needs of both types of batteries, resulting in a more organized lab environment.
2. Quick and flexible switching: The two-in-one design allows users to quickly switch between coin-type and pouch-type batteries without needing to adjust equipment, change cables, or fasten locks. Sample changeover can be completed within seconds, greatly enhancing testing efficiency.
3. Easy and intuitive operation: The fixture design for coin-type batteries uses a four-wire probe with a dedicated holder, ensuring accurate positioning and secure fixation. When switching to pouch batteries, the lower four-wire clamp can be quickly connected. The separate tray for coin batteries and quick-plug connector design for pouch batteries allow users to do preparatory work on other workbenches, further saving operation time.
