The second research area is the study of nanostructured electrodes for energy storage and conversion.<\/span>\u00a0The group has two avenues for the synthesis of electrodes for energy storage: those based on SiNWs and composites with CNT fibres (Figure 2). The group has demonstrated a scalable method to fabricate Li-ion battery anodes that eliminates all solvents and mixing steps. This has the potential to reduce cost and avoid emissions in LIB cell manufacture of the order of 48kg CO2<\/span>\/kWh, or equivalent to around 2 tonnes of CO2<\/span>\u00a0per electric vehicle. The anodes have > 75wt.% Si and high-performance properties. Their networks structure enables reaching high areal capacity (> 9mAh\/cm2<\/span>), and under repeated cycling prevents pulverisation and preserves electronic conductivity. The anodes are thus strong candidates for the next generation (3b, 4a) LIBs.<\/p>

The second type are CNT fibres are used as scaffolds for composite electrodes produced by textile-like methods and leading to built-in current collectors that eliminate binders and low added-value carbons (LAVCs). The group has spent the last ca 5 years developing synthetic routes to grow active materials in the internal pores of CNT fibres, studying their complex structure, and performing extensive electrochemical studies to establish a clearer nexus between 3D structure, transport properties, mechanical properties and electrode performance.\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
