In an effort to showcase the immense versatility of this technique, a similar process was designed to create a 3D porous carbon-silicon composite anode using chitosan as a carbon precursor. Chitosan, the second most abundant polysaccharide on earth, is primarily derived from the shells of crustaceans. As a food-waste by-product, it is widely available and extensively researched for use in functional applications. The galvanostatic cycling performance of said anode at a current density of 300 mA/g with similar mass loading is displayed in Figure , showing excellent cyclic stability with a gravimetric capacity of 780 mAh/g after 100 cycles. HRSEM imaging, Raman analysis and experimental information is available in supplementary figure . While the many reasons for specific use of jellyfish biomass were discussed in detail, there is the need to highlight the fact that this method is applicable in many different configurations. Fundamentally, this work aims to emphasize that the transformation of carbon precursors embedded with electrochemically active material into additive-free conductive carbon composites for a wide variety of battery applications via laser irradiation can be utilized extensively with an immense array of readily available carbon sources and active materials. The excellent electrochemical performance displayed by JF/SiNP composite anodes can be directly related to their unique structure and is further investigated in the post-mortem analysis in Figure of the JF/SiNP cell that ran for 1170 cycles (Figure ). The now amorphous SiNPs can be observed to be still completely encapsulated within the conductive carbon matrix after cycling in Figure , showing that the mechanical integrity of the carbon matrix can sufficiently function as a buffer to mitigate the severe volume expansion of silicon during lithiation for many cycles, reducing the likelihood of loss of active material due to pulverization and cracking. Essentially, the absence of such a buffer may also lead to fracturing of the solid electrolyte interphase (SEI) layer, resulting in recurrent formation and breakdown of unstable SEI layers. Accordingly, the EDS analysis of Fluoride (from the LiPF6 in the electrolyte) shown in Figure shows the uniform dispersion of the SEI throughout the carbon matrix, contributing to the enhanced stability of JF/SiNP batteries and indicating that the wetting of the electrolyte was optimal . As evidenced by the rate performance capabilities of the cells depicted in Figure , the incorporation of silicon encapsulated in conductive carbon can augment electrode conductivity by facilitating an advantageous continuous pathway for electron transport. The anode material is also directly deposited on the current collector during the synthesis and prior to battery assembly, ensuring sufficient adhesion and optimal electrical contact. The same is true for the increase in porosity of the anode material as a result of the development of the 3D porous carbon polymorph architecture, with the increase in contact area between the encapsulated silicon and electrolyte enabling enhanced wetting and ion transport . Through the mitigation of recurrent SEI layer breakdown and active material loss caused by pulverization, as well as the improvement of ion and electron conductivity, the stability and capacity of the batteries is significantly enhanced . Consequently, due to the cumulative effect of these factors on JF/SiNP battery performance, use of conductive additives or binders can be eliminated, as corroborated by the electrochemical analysis.
