项目摘要
1. Development of electrolytes from fatty acids of vegetable oilsLinoleic acid was shown to be more suited for usage as electrolytes in both the cation and anion parts than electrolytes made from ricinoleic acid, since the linoleic acid-based electrolytes demonstrated a lower viscosity and a higher conductivity. However, due to its high viscosity, its EDLC capacitance remained low. Propylene carbonate (PC) was added to the electrolytes to lower their viscosity. As expected, an increase in the capacitance of the EDLC was found.2. Development of EDLC parts, electrode and separator, from hardwood kraft lignin (HKL)From an electrospun HKL fiber mat, a separator as tHKL separator and two types of electrodes (mat type and power type) can be made. The EDLC was fabricated using a mat type of electrode and a tHKL separator and demonstrated remarkable energy and power densities. Although a powder type electrode requires a casting method to prepare, its EDLC demonstrated excellent electrochemical performance, extremely high power density, low resistances, and good capacitance stability, which were attributed to the powder type electrode's smooth surface and the resulting good contact with the separator.
1.从植物油脂肪酸中开发电解质亚油酸比蓖麻油酸制成的电解质更适合用作阳离子和阴离子部分的电解质,因为亚油酸基电解质表现出较低的粘度和较高的电导率。然而,由于其高粘度,其EDLC电容仍然较低。将碳酸丙烯酯(PC)添加到电解质中以降低其粘度。正如预期的那样,发现EDLC的电容增加。从硬木硫酸盐木质素(HKL)开发EDLC部件、电极和隔膜。从电纺HKL纤维垫,可以制造作为tHKL隔膜的隔膜和两种类型的电极(垫型和功率型)。EDLC使用垫型电极和tHKL隔膜制造,并表现出显着的能量和功率密度。虽然粉末型电极需要铸造方法来制备,但其EDLC表现出优异的电化学性能,极高的功率密度,低电阻和良好的电容稳定性,这归因于粉末型电极的光滑表面和与隔膜的良好接触。
