Nanomechanical testing - batteries

The stability in charge-discharge rates with increasing number of electrochemical cycles dictate the lifetime of a battery. To improve the lifetime, the relationship between the battery degradation mechanism and the mechanical properties of the electrode and separator coatings has been explored. It has also been understood that the degradation rate is not only dependent on the electrochemical reactions, but also on the mechanical stability and properties of the coatings and materials respectively. To achieve the goal of significantly improving the efficiency, one other approach could be processing optimisation of various battery components and further mechanical characterisation at different degrees of electrochemical cycles. Nanomechanical testing is an established characterisation technique with proven versatility and much needed sensitivity for process optimisation in the battery industry, both in R&D andmanufacturing.
