Polyaniline electrode on a graphite substrate was produced and evaluated for use in an ionic liquid electrolyte for supercapacitor applications. The aniline monomers were added in Ethaline deep eutectic solvent electrolyte. The deep eutectic solvent is a type of ionic liquid consisting of only ions without water. Aniline was polymerized electrochemically onto graphite current collector from a non-aqueous and non-acidic Ethaline electrolyte. Polyaniline film obtained in Ethaline had homogenous agglomerated nanoparticles. Growth of polyaniline was not autocatalytic reaction in ionic liquid media and the rate of its growth slowed down upon increasing time. Electropolymerized polyaniline was transferred in two different electrolytes (acetonitrile containing LiCIO₄ solution and monomer-free Ethaline) to determine the electrochemical properties of the polyaniline coated graphite electrodes by cyclic voltammetry and galvanostatic charge-discharge techniques. The capacitance of the modified electrode retains 87% of its initial value after 10,000 cycles in Ethaline electrolyte because the polyaniline electrode was probably not effected from swelling and shrinking in an anhydrous ionic liquid for long cycles. The electrode deposited from Ethaline ionic liquid medium and cycled in pure Ethaline electrolyte had a specific capacitance of 833 F g⁻¹ at 20 mV s⁻¹ scan rate. The polyaniline coated graphite electrode electrodeposited using one-step polymerization in Ethaline media is a promising electrode for high-performance supercapacitors that can be used in non-aqueous electrolytes.

制备了石墨基材上的聚苯胺电极，并对其用于超级电容器的离子液体电解质进行了评估。将苯胺单体添加到Ethaline深低共熔溶剂电解质中。深共熔溶剂是仅由离子组成而不含水的一种离子液体。将苯胺从非水非酸性Ethaline电解质中电化学聚合到石墨集电器上。在Ethaline中获得的聚苯胺薄膜具有均匀的团聚纳米颗粒。聚苯胺的生长不是在离子液体介质中的自催化反应，并且随着时间的增加，其生长速率会减慢。将电聚合的聚苯胺转移到两种不同的电解质中（含LiCIO _4的乙腈溶液和不含单体的乙醇），通过循环伏安法和恒电流充放电技术确定聚苯胺涂层石墨电极的电化学性能。在thathaline电解质中，经过10,000次循环后，修饰电极的电容保持其初始值的87％，因为聚苯胺电极很可能不受长时间在无水离子液体中的膨胀和收缩的影响。从Ethaline离子液体介质沉积和在纯Ethaline电解质循环的电极具有833 F G的特定电容^-1在20毫伏小号^-1扫描速度。使用一步聚合在Ethaline介质中电沉积的聚苯胺涂层石墨电极是用于高性能超级电容器的有希望的电极，该超级电容器可用于非水电解质中。
