Jute fiber based micro-mesoporous carbon: A biomass derived anode material with high-performance for lithium-ion batteries

Abstract Jute fiber has been used as carbon precursor to prepare micro-mesoporous carbon material applying as anode materials for lithium ion battery. The main step was to use different quantity of zinc chloride as an activator under the carbonization at high temperature in the air atmosphere, and then an activated carbon material with prosper porosity and high specific surface area of 1028.614 m2 g−1 was obtained and named JFAC. The obtained micro-mesoporous structure benefits the lithium transfer in the active anode material. The impact of JFACs on the electrochemical performance was evaluated, showing its outstanding cycle stability and specific capacity with 742.7 mA h g−1 after 100 cycles at 0.2C. A discussion of the quantity of zinc chloride activator was exhibited and this method finally shows the high efficiency of zinc chloride for the activation of biomass carbon materials.
