As is mentioned above, CNT arrays have great potentials for the applications of plasma-flashover cathodes due to their excellent field emission properties [5 8].
Na3V2(PO4)3 (NVP) is regarded as one of the most potential SIBs cathodes due to its high theoretical capacity and stable sodium superionic conductor (NASICON) structure.
Compared with PI, PPy is more suitable for coating on surface of LNMO cathodes due to its remarkable electrical conductivity, lightweight, environmental friendliness, good mechanical flexibility, chemical stability, and theoretical capacity of 72 mAh g−1 in LIBs.
Manganese dioxide and lithiated variants are a promising alternative to conventional Li-ion cathodes due to their cost, abundance, safety and electrochemical performance.
Functionalization of carbon surface leads to the enhancement of ion storage capacity of carbon cathodes due to the additional pseudocapacitive reactions.
The lithium metal silicates (Li2MSiO4) (where M = Mn, Fe, and Co) have a great potential in rechargeable lithium ion batteries as polyanion cathodes, due to the immanent merits such as superior electrochemical properties, low cost, and abundance.
However, the battery type electrodes usually exhibit sluggish reaction kinetics than capacitor type cathodes due to slow Na ion insertion and extraction, which greatly hinders the rate performance.
The InBaCo4−xZnxO7 + GDC (50 50 wt.%) composite cathodes exhibit improved cathode performances compared to those obtained from the simple InBaCo4−xZnxO7 cathodes due to the extended triple-phase boundary (TPB) and enhanced oxide-ion conductivity through the GDC portion in the composites.
Fuel cell data collected with electrolyte-supported and anode-supported single cells reveal that the La1.85Sr1.15Cu2−xCoxO6+δ + GDC (50 50 vol.%) composite cathodes exhibit lower polarization resistance compared to the pure La1.85Sr1.15Cu2−xCoxO6+δ cathodes due to the extended triple phase boundary (TPB) where the ORR occurs.
This new experimental system shows electronic background currents that are ∼3 times higher than that previously reported, experimental peak currents in excellent agreement with the current predicted in our thin layer three-phase interline (3PI) model, and large pores in Ti cathodes due to a Kirkendall-like effect.
