Design for recycle: alternative binders for optimising recyclability Sean Scott, Andrew P. Abbott, Karl S. Ryder University of Leicester, UK Electric vehicles (EVs) have become an increasingly common sight on the world’s roads in the past decade. Additionally, countries like the UK plan to stop the sale of vehicles solely using the internal combustion engine by 2030. Development of these batteries is critical, often focusing on issues regarding extending range and lifetime, while overlooking end-of-life treatments. Current binders, such as PVDF (polyvinylidene fluoride), hinder recycling processes due to their high stability, requiring toxic solvents and high temperatures to separate battery components for subsequent recycling procedures. This poster aims to give an introduction to the idea of ‘design for recycle’ with regards to the batteries that power electric vehicles. Binders will be focused on, detailing issues with the separation of electrode components during recycling due to the PVDF binder before discussing how alternative binders can improve this step, which facilitates simpler subsequent recycling processes. Two alternative binders are focused on,sodium alginate and gelatin, which are also modified with a deep eutectic solvent modifier. Electrodes created using these novel binder systems are then characterised with regards to their adhesion (scratch test), thermal stability (differential scanning calorimetry and thermogravimetric analysis) and recyclability (ultrasonic delamination) 1 .
