Anodizing applications

Anode Applications. Graphite has been used as the primary material for electrolysis of brine (aqueous) and fused-salt electrolytes, both as anode and cathode. Technological advances, however, have resulted in a dimensionally stable anode (DSA) consisting of precious metal oxides deposited on a titanium substrate that has replaced graphite as the primary anode (38—41) (see Alkali and chlorine products). 

Chen et al. reported the synthesis of sulfur/polythiophene composites with core/shell structure through an in-situ chemical oxidative polymerization method for LIB cathode. Using a low viscosity electrolyte of 1,3-dioxolane (DOL)/dimethoxy ethane (DME), the composite with 72 wt% of sulfur was cycled at a current density of 100 mA/g and retained 74% of its initial capacity (1120mAh/g) after 80 cycles [47]. Polythiophene (PTh) coated with ultrathin MnO nanosheets was synthesized through one-step aqueous/ organic interfacial method for LIB anode application. The as-synthesized MnOj-polythiophene nanocomposite delivered a reversible capacity of 720 rnAh/g and retained 500 mAh/g after 100 cycles at a high current density of 500 mA/g [48]. 

Fe20j PANI was obtained using simultaneous one-step in-situ polymerization and chemical etching process in the same reactor for LIB anode application. Discharge capacity of 1208 mAh/g was exhibited by Fe O PANI electrode with a 73.5% columbic efficiency [59].

There are certain possibilities for the optimization of the structure, yet it seems less likely that some new materials might be applied instead of N-SiC. The changes might be a drained cathode and inert anode application. 

Material choice is crucial to produce a successful fuel cell. Alternative Materials for SOFCs, Opportunities and Limitations touches on materials and their suitability for both electrolyte and anode applications. The chapter finishes on the use of redox stable anodes to improve overall fuel utilization, and the in situ formation of nano-structure to improve electrode performance.
