Carbon Additives in the Negative Electrode
•Automotive (micro HEV, e-bikes) •Energy storage •Industrial (fork-lifts, back-up systems, medical devices) •Good wettability for paste processing and electrolyte supply to the negative electrode •High affinity to lead for an efficient lead plating on the negative active mass (NAM) skeleton•Good electrical conductivity to reduce electrode resistivity and represent active electrode component
•Sufficient BET specific surface area (SSA) and double layer capacitance for dynamic charge acceptance (capacitor effect) •Sufficient purity to reduce gassing and self-discharge •Balanced particle size distribution for homogeneous incorporation into electrode structure •Improved cycle life •Improved charge acceptance In literature the following solutions are proposed: •Low surface area carbon (graphite/expanded graphite mixed with low SSA carbon black) [a] •High surface area carbon (graphite/expanded graphite mixed with high SSA carbon black) [b] [a] D.P.
