The article talks about how to make high-quality coin cells. The performance of new materials in lithium-ion batteries is usually evaluated with hand-made half coin cells with the new material as the positive electrode and a piece of lithium chip as the negative. Half coin cells are easy to make and can give reproducible data. …
One may encounter the problem that battery cell cycler software upgrade is needed but there are still tests ongoing on the channels of the battery cell cyclers. Actually, the software could be updated without losing all the settings. After the update, the ongoing tests can be resumed. You don’t need to restart the battery cyclers …
What is Internal Resistance (IR) and how to test battery resistance A battery can be regarded as an ideal voltage source in series with an impedance, which is called internal resistance. When the battery works, the voltage output is lower than the open-circuit voltage (abbreviated as OCV). The difference is the voltage drop caused by the …

Re-assign unit number for battery testers The program does not allow two testers to have the same unit number (Box No.). If two testers have the same Unit No., at least one could not be recognized by the computer. In the advanced setup of the LANDCali, Unit No. can be re-assigned. The Current and Voltage …
