Plant-based carbon materials are a high-demand source nowadays, as they are low-cost, eco-friendly, easily available, and sustainable.  Borassus flabellifer (Palmyra palm) is a gift of nature that gives numerous benefits, as all parts of the tree can be used for multiple purposes. Palmyraculture is the practice of cultivating Palmyra palms and utilizing them to live a self-reliant life in working towards sustainable development. Due to the advancement of technology, Borassus flabellifer is used to synthesize carbon materials, including hard carbon, carbon nanodots, charcoal, and activated carbon.  These carbon materials can be used in electrochemistry as anode materials, biosensing, bioimaging, catalysts, and water purification. This review mainly focuses on the carbon materials derived from the Borassus flabellifer, their applications in various fields, and further aspects that have to be considered.

Negative Electrode Material

Graphite is widely used as the negative electrode material. To find out the influence of several different modified ways on the material's electrochemical performance, the electrochemical properties of 0318、0318-GLQ、MCMB22、AGP-3-2、AGP-3-2-1 and AGP-3-2-2 batteries were investigated by means of cyclic voltammetry (CV) experimental method. Results show that surface morphology, lithium intercalate/de-intercalate process, the first coulombic efficiency, reversibility and rate capability are all different for different material. Above all, AGP-3-2-2 has the best electrochemical performance, AGP-3-2 is worst, and the results prove that coating by pitch has a positive influence on the electrochemical performance of the material.

<p>As a negative electrode material for lithium ion batteries (LIBs), carbon has a higher cycle life and higher safety. However, it has poor electrical conductivity, low charging and discharging platform, and poor stability of layered structure. Some carbon materials are complicated to make such as synthetic graphene, and the shape is difficult to control. Metal materials have good electrical conductivity, but due to the rapid volume expansion of lithium ions during the cycle of insertion and extraction, the electrodes are extremely quickly crushed and accompanied by extremely rapid capacity decay. Scholars have combined the advantages of carbon and metal materials to create a new type of carbon-based composite material. This article outlines the use of carbon based composite materials as lithium-ion electrodes to improve battery performance.</p>
