Extraction of cellulose rope bamboo (Gigantochloa apus) as a material for sustainable lithium ion battery technology

Solid electrolyte materials made out of natural polymers as components of lithium-ion battery cells were interesting. Cellulose-based biopolymer material had prepared from a rope bamboo (Gigantochloa apus) using a microwave-assisted extraction (MAE) method. The first step carried out an identification of cellulose content of rope bamboo with data analysis on the Chesson-Datta method. The rope bamboo was delignification using an alkaline solution, where the rope bamboo material soaked by 2% NaOH solution for 1 day. A sample inserted into the microwave at 50°C for heating with a various duration (30, 40, and 50 minutes). The samples were characterized by X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and Particle Size Analyzer (PSA). The cellulose content of rope bamboo after delignification was 72% and 2% lignin. The result of XRD analysis showed that the diffraction pattern of the three samples showed an amorphous cellulose-Iα structure the best crystal size based on the hkl (121) plane of the 30 minutes heating variation sample was ∼35 nm. The result of FTIR analysis proved the presence of hydroxyl and carboxyl functional groups in sample of rope bamboo. The result of SEM analysis confirmed the morphological structure of cellulose that forms the fibers, with the best particle size distribution at 30 minutes heating variation was ∼1.5 µm on PSA analysis.
