Abstract

Graphene paper (GP) with layered structure and highly conductive network is fabricated by a facile technique of vacuum filtration and studied as a single-component and binder-free anode of lithium ion batteries (LIBs). The process of fabrication of GP without any binder and high-temperature treatment, in the meantime, great improvement in both the capacity and cycling performance of the GP electrodes have compared with other kinds of traditional graphite electrode materials. Given the simplifying anode fabrication, low manufacturing costs and many electrochemical properties of the GP anode, it is regarded as an excellent anode material of LIB with great promise for its both excellent cycling performance and electrochemical properties. The specific capacity can reach to over 200 mAhg-1after 60 charge-discharge cycles under the current rate of 50 mAg-1.

Abstract

The study aimed to describe the alkaline treatment advantage to remove ash component from natural rice straws. Most of the ash component in the rice straw is silica. High ash content is particularly harmful to cutting tools and to chemical to recovery systems in the pulp paper industry. In this study, the silica content has been removed simply through by immersion process in the 5% sodium hydroxide solution to obtain de-silicated rice straw. The study revealed the effectiveness of this alkaline process and the compatibility in commercial practice. The rice straw pulping is considered competitively to complement the global demand of raw material in paper production. Therefore, the treated rice straw plays an important role in providing raw material in the form of wood and rice straw blend feedstock for pulp and paper industry.
