COATING OF LFP/GRAPHENE OXIDE ON CARBON FIBRES AS POSITIVE ELECTRODES FOR STRUCTURAL BATTERIES
Paper in proceeding, 2022

Structural battery composites are carbon fibre-based materials with the ability to simultaneously carry mechanical load and store electrical energy. This study investigates a method for manufacturing structural positive electrodes via electrophoretic deposition (EPD). Electrostatic forces on different scales are exploited in the EPD process. On the nanoscale, electrostatic interactions are employed for self-assembly of the nanometric components, followed by EPD on the macroscale with carbon fibres immersed in organic solution to attract the nanoscale components. Hereby, we use LiFePO4 as the active material, where electrochemically exfoliated graphene oxide (EGO) is compared with reduced graphene oxide (rGO) as a multifunctional carbon additive.
