      abstract     = {The drying of electrodes for lithium-ion batteries is one
                      of the most energy- and cost-intensive process steps in
                      battery production. Laser-based drying processes have
                      emerged as promising candidates for electrode manufacturing
                      due to their direct energy input, spatial homogeneity within
                      the laser spot, and rapid controllability. However, it is
                      unclear to what extent electrode and cell quality are
                      affected by higher heating and drying rates. Hybrid systems
                      as a combination of laser- and convection-based drying were
                      investigated in an experimental study with water-processed
                      LFP cathodes. The manufactured electrodes were compared with
                      purely laser-dried and purely convection-dried samples in
                      terms of drying times and quality characteristics. The
                      electrodes were characterized with regard to physical
                      properties like adhesion and electronic conductivity, as
                      well as electrochemical performance using the rate
                      capability. Regarding adhesion and electronic conductivity,
                      the LFP-based cathodes dried in the hybrid-drying process by
                      laser and convection showed similar quality characteristics
                      compared to conventionally dried cathodes, while, at the
                      same time, significantly reducing the overall drying time.
                      In terms of electrochemical performance, measured by the
                      rate capability, no significant differences were found
                      between the drying technologies used. These findings
                      demonstrate the great potential of laser- and
                      convection-based hybrid drying of LFP cathodes to enhance
                      the electrode-drying process in terms of energy efficiency
                      and operational costs.},
