大家好！我想购买能测压缩的粉末（pellets) 或膜的（through-plane) 电导率的电池池（conductivity cell for solid samples). 坛子里谁知道国外哪家公司有卖这个器件吗？谢谢！ （我知道原则上可以自己做，但是费时间） (我已咨询BioLogical，Metrohm, Fumatech, Solartron 等公司） I am looking for commercial conductivity cells for measuring the conductivity of solid samples (e.g. pressed pellets with a certain thickness). Here I show some experimental examples: Example I: Impedance analysis was performed on pristine powders. The powders were then added to a standard 13 mm die, sandwiched between two porous carbon electrodes and pressed at 5,000 kg for 2 min. All pellets were 13 mm in diameter and ranged in thickness from 1.30 to 1.38 mm. Measurements were performed using an impedance with a two-probe electrochemical cell equipped with platinum current collectors. Measurements were taken in the temperature range of 30 to 150 oC. Example II: Conductivity cell for measuring conductivity of solid salts (see the attached picture) Example III: Small accessory for measuring the through-plane conductivity of ionomer membranes (like Nafion...)
