Cell Component Mechanical Tests

zwickroell tensile testing of 6 um thick copper foil

Cell component mechanical tests are extensive and required in order that a more detailed understanding of how the cells behave can be established. The battery cell is a complex: chemistry, electrical, thermal and mechanical system. Cycle ageing is seen as a deteriation in the chemistry of the cell, but should also be considered as a … Read more

Measurement of Open Circuit Voltage

open circuit voltage versus SoC for different chemistry

The measurement of Open Circuit Voltage can be time consuming as it needs to be established versus the State of Charge (SoC) of the cell. Doing this in fine steps from 0% to 100%, with the measurement being made “at rest”, means we have to charge/discharge and then let it rest before making the voltage measurement. The … Read more

How Can Gas Chromatography-Mass Spectrometry Improve Li-ion Battery Performance?

Maintaining battery production quality and improving performance, lifetime, and safety requires application of a variety of analytical techniques. Confirming material composition and purity, ensuring the homogeneity of electrode slurries, detecting defects that can cause short circuits and certifying feedstock materials extracted from recycled batteries are all processes that depend on analytical testing. Investigating the mechanisms … Read more

Making energy greener – what role does elemental analysis play?

elemental analysis

In the drive towards a future that is no longer dependent on burning fossil fuels for energy generation, several technologies have become established as front runners in the race to reduce carbon emissions and improve air quality. Among the most significant are lithium ion batteries, biofuels and renewable energy sources, such as wind power. Aside from … Read more
