Overview

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.

Research activities

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.

Outcomes

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.

Skills and experience

A suitable student must possess:

  • a strong sense of safety consciousness in an industrial lab environment
  • an interest in energy storage challenges
  • data recording and analysis skills
  • a background in physics, chemistry, or engineering.

Desirable skills and attributes include:

  • knowledge of battery electrochemistry and
  • cell construction
  • interest in process engineering
  • (computational) modelling skills
  • a curious attitude.
