Full Automation

The BSD-660 series offers complete automation throughout the entire testing process, including self-checks, free zone measurements, material activation, and in situ adsorption testing. It eliminates the need for manual handling of sample cells, heating furnaces, or Dewar cups, allowing researchers to focus on higher-level analysis rather than repetitive tasks. Once material activation is complete, the system automatically manages the entire workflow—performing in situ degassing, adjusting the heating furnace, and switching between Dewar cups with LN2 or a water bath as required. With its high-throughput capabilities and fully automated operation, the BSD-660 enhances lab efficiency, precision, and functionality, delivering a seamless, hands-free testing experience.

Pressure Control Heating

The Pressure-Controlled Heating (PCH) function intelligently adjusts the heating rate based on real-time pressure signals, ensuring a stable and controlled outgassing process. This precision control protects the integrity of pore structures, preventing damage during testing. Additionally, the PCH function minimizes the risk of material powders being displaced and carried into the pipeline or manifold, preserving both the sample and the system's functionality. This feature ensures optimal performance and reliability throughout the testing process.

Potassium Metal Underpotential Deposition in Crystalline Carbon of Potassium-Ion Batteries Tianyi Ji, Xiaoxu Liu,* Tengsheng Zhang, Yunli Shi, Dawei Sheng, Hangtian Yin, Ze Xiang Shen, and Dongliang Chao*

Carbon materials, owing to their low cost, high conductivity, and good thermal and chemical stability, have been deemed as a promising anode candidate for potassium-ion batteries. However, anomalous low-voltage discharge situations in crystalline carbon materials imply uncertainty in the potassium storage mechanism. Herein, an overlooked scenario, i.e., potassium metal underpotential deposition (PMUPD), is disclosed in crystalline carbon materials for the first time. The study unveils the induction of interlayer pores on desolvation and PMUPD by insights from thermodynamics, kinetics, and experimental analyses. By manipulating the cutoff voltage to utilize partial PMUPD, a novel synergistic mechanism of co-intercalation and PMUPD is revealed. A remarkable initial coulombic efficiency of 92% and a 65% capacity retention at 30C (80 mAh g−1) are realized in crystalline carbon anode. This work provides a new insight into the potassium storage mechanism of carbon anode and contributes to further research and application of the UPD behavior in other alkaline metal ion batteries.
