Calendering is the process of compressing and smoothing out a material by passing it between two rollers. This is a critical step of manufacturing thin films for energy storage and other applications, but one that can often be overlooked at a research level.
This project will investigate the effect of calandering on electrode materials for lithium-ion batteries. The aim is to find the optimum amount calendaring for maximum film quality and performance.
The activities a VRES student could be involved with include:
- assisting in manufacturing anode and/or cathode films.
- gathering quantitative and qualitative data such as:
- calendering settings
- film thicknesses
- scanning electron microscope (SEM) images
- conductivity readings
- cell performance data.
- collating and analysing data to propose appropriate models for optimising calendaring settings.
The aim is to find the optimum amount calendaring for maximum film quality and performance.
There are a range of variables in producing electrodes which may be selected based on the desired characteristics of a battery cell. Therefore it is reasonable that optimal calendering settings are a function of multiple parameters, such as electrode type, desired cell power, cell energy, and cell life.
The ultimate long-term goal of this research is to gain knowledge of what the optimum calendering settings are over a range of targeted electrode configurations.
