“…After cycling, both unit cell parameters a and c of three samples increase, but the c/a of PANI‐HTFSI@LMO changes the least and it maintains the best lamellar structure (c/a values greater than 4.9 have good lamellar properties) 29,30 . The value of I (003) / I (104) can determine the degree of Li + and Ni 2+ mixing in Li‐rich materials 31‐33 . The values of I (003) / I (104) before cycling were all greater than 1.3, demonstrating a low degree of blending of Li + and Ni 2+ in the material 34 .…”

Summary A thin polyaniline layer that was covered on the surface of the microrod‐like lithium‐rich Mn‐based oxide (LMO, Li1.2Mn0.54Co0.13Ni0.13O2) was formed by in‐situ polymerization of the aniline monomer in HCl or (CF3SO2)2NH (HTFSI) aqueous solution. The results of morphology analysis and structural characterization show that the uniform polyaniline coating layer has a thickness of 6 to 8 nm and the polymerization process does not spoil the integrity of the LMO microstructure. Electrochemical impedance spectroscopy and constant charge/discharge measurement show that polyaniline coating can significantly decrease the interfacial charge transfer resistance, and improve cyclic stability by reducing electrolyte corrosion. Cycling at the current density of 0.1 A g−1 for 100 cycles, the polyaniline‐coated LMO synthesized in HTFSI acidic media exhibits the discharge capacity of 212.2 mAh g−1and high stability (91.98% retention of initial capacity). The high performance is a result of the activation of LMO in HTFSI acidic solution and the role of the (CF3SO2)2N− counterions in the polyaniline chains.

A continuous flow enzymatic fuel cell (EFC) based on poly(pyrrole-co-pyrrole-2-carboxylic acid) film was used for sustainable energy generation. The system parameters were optimized to generate maximum power. Optimum cycle number for electropolymerization was found to be 12.5 for bioanode, and 20 for biocathode.The best performance was reached at pH 7, 1 ml min À1 flow rate and cell potential of 0.51 V. A power density of 0.36 μW cm À2 in 10 min was generated with 0.86 μg glucose dehydrogenase and 0.35 μg bilirubin oxidase enzyme quantity by using 100 mmol L À1 glucose. The EFC performance was investigated with municipal sewage, and the system generated a power density of 0.85 μW cm À2 . Results showed that the proposed EFC could be successfully used at waste utilization, especially for the wastewater with glycolytic content.
