Problems solved by technology

[0003] my country is a large agricultural country, with the output of various crops reaching more than 700 million tons of straw after maturity, except that it is used as fuel, building materials, feed and fertilizer, and power generation, there are still 60% of which cannot be effectively used and are destroyed. Disposal not only causes a large amount of waste of biomass energy, but also has a certain impact on the environment

Abstract

The invention discloses a light-metal-doped straw based carbon electrode material which is characterized in that the material is prepared by the following parts of raw materials by weight: modified straw composite material 110-120, zeolite powder 2-3, light metal 4-5, ruthenium dioxide 1-2, calcium stearate 1-2, lithium perchlorate 2-3, nickel hypophosphite 1-2, sodium dodecyl sulfate 1-2, binders LA1321-2 and proper amount of deionized water. Carbonization, activation and doped modification are performed on crop straw to prepare high-activity and high specific surface area carbon. The additionally arranged light metal can accelerate charging speed of a capacitor so that time is saved and charging capacity is enhanced. The electrode material has excellent characteristics of high capacity, high multiplying power and long cycle.

Description

technical field [0001] The invention relates to the field of chemical energy materials, in particular to a light metal-doped straw-based carbon electrode material and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the rapid growth of the population, the resources and energy that human beings rely on are increasingly exhausted. The development of economical and efficient new energy is an important issue in today's world to solve these problems. On the one hand, people vigorously develop wind energy, solar energy, ocean energy and nuclear energy. On the other hand, scientists are actively developing new energy-saving and efficient energy storage devices. Supercapacitor, namely electrochemical capacitor, is a new type of energy storage element with energy density and power density between traditional capacitors and secondary batteries. The emergence of supercapacitors makes the capacitance of capacitors reach the Fara...
