Vanadium pentoxide and conducting polymers have promising applications in the field of elec. energy storage devices and combine flexible substance to form binder-free ternary electrodes, which would pave a new way for designing supercapacitors. Herein, graphite felt (GF)@V2O5 nanosheets is synthesized by hydrothermal and calcinating treatment, on the surface of which polyindole (PIn) nanospheres are anchored orderly using electrochem. deposition to obtain GF@V2O5@PIn ternary electrode material. The pseudocapacitive properties of both V2O5 nanosheets and PIn nanospheres are fully demonstrated through the synergistic effect of them, enabling ternary composite GVP-3 to exhibit superior electrochem. properties than two binary materials. The area capacitance of GVP-3 reaches 2254 mF/cm2, which is significantly higher than that of GF@V2O5 with 1431 mF/cm2 and GF@PIn with 647 mF/cm2. The flexible quasi-solid-state asym. supercapacitor (FASC) can be operated at the potential window of 1.8 V with a significant energy d. of 1.423 mWh/cm3 (64.404Wh/kg) The excellent elec. capacitance and prominent energy d. of our device endow it with an overall improvement of elec. performance from 25% to 30%, which is compared to present researches. Two devices connected in series are able to make a 3.5 V LED bump light up normally for 2 min, illustrating desirable practicality. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Application of 7447-41-8).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Application of 7447-41-8
