“…The consistency of R CT values reciprocates the formation of a stable and durable SEI layer over the electrode surface. [ 35 ] The attaining stable and robust SEI layer over the SnO 2 electrode in the absence of EC is a significant improvement possible with a slightly higher conductive additive, limited working potential, and electrolyte additive, FEC.…”

Dual‐ion batteries (DIBs) are considered one of the promising energy storage devices in which graphite serves as a bi‐functional electrode, i.e., anode and cathode in the aprotic organic solvents. Unlike conventional lithium‐ion batteries (LIBs), DIBs reversibly store the cations and anions in the anode and cathodes during redox reactions, respectively. The electrolyte is a source for both cations and anions, so the choice of electrolyte plays a vital role. In the present work, the synthesis of SnO2 nanostructures is reported as a possible alternative for graphite anode, and the Li‐storage performance is optimized in half‐cell (Li/SnO2) assembly with varying amounts of conductive additive (acetylene black) and limited working potential (1 V vs Li). Finally, a DIB using recovered graphite (RG) fabricated from spent LIB as a cathode and SnO2 nanostructures as an anode under balanced loading conditions. Prior to the fabrication, both electrodes are pre‐cycled to eliminate irreversibility. An in‐situ impedance study has been employed to validate the passivation layer formation during the charge‐discharge process. The high‐performance SnO2/RG‐based DIB delivered a maximum discharge capacity of 380 mAh g−1. The electrochemical performance of DIB has been assessed by varying temperature conditions to evaluate their suitability in different climatic conditions.

“…Electric double-layer types of materials are made up of various carbonaceous materials including carbon nanofibers, activated carbon, and graphene, which store electrical charges through physical absorption-desorption processes at the electrode-electrolyte interface [14][15][16]. In this regard, electric double-layer types of materials exhibit advantages such as high power density and long-term cyclability [17][18][19]. However, the potential applications of electric double-layer types of materials are constrained by their low specific capacitances [20].…”

In this study, Al paper and cellulose acetate (CA) filters derived from heated tobacco waste were successfully converted into current collectors and active materials for a supercapacitor device. Typically, heated tobacco contains electrically discontinuous Al paper. First, Al was extracted from the tobacco waste using HCl to produce Lewis acid (AlCl3). This acid was then used in an Al electrodeposition process utilizing the chloroaluminate ionic liquid reaction between the acid and the base (RCl) at room temperature. To enhance the conductivity, a supplementary coating of Al metal was applied to the Al paper through electrodeposition, thus re-establishing the electrical continuity of the discontinuous parts and forming an Al-coated current collector. Moreover, the CA filters were carbonized under a nitrogen atmosphere, yielding carbon precursors (C-CA) for the supercapacitor electrodes. To further enhance the electrochemical performance, nickel oxide (NiO) was incorporated into C-CA, resulting in C-CA@NiO with pseudocapacitance. The specific surface area of CA increased with carbonization and the subsequent incorporation of NiO. The as-synthesized C-CA and C-CA@NiO materials were applied to an Al-coated current collector to obtain C-CA- and C-CA@NiO-based electrodes, exhibiting stable electrochemical behavior in the voltage range of −1.0 to 0 V and 0 to 1.0 V, respectively. An asymmetric supercapacitor (ASC) device was assembled with C-CA@NiO and C-CA as the positive and negative electrodes, respectively. This ASC device demonstrated a high specific capacitance of 40.8 F g−1, while widening the operating voltage window to 2.0 V. The high electrochemical performance of the device is attributed to the successful Al electrodeposition, which facilitates the electrical conductivity and increased porosity of the C-CA@NiO and C-CA materials. To the best of our knowledge, this is a pioneering study in regards to the conversion of biomass waste into current collectors and active materials to fabricate a practical ASC device. Our findings highlight the potential of reusing Al paper and CA filters from heated tobacco waste as essential components of energy storage devices.

Lithium-ion capacitors (LICs) are the next-generation electrochemical energy storage devices with two different types of energy storage mechanisms, anode and cathode. The LICs are anticipated to bridge the gap between lithium-ion batteries and supercapacitors by providing higher energy and power density than the individual charge storage systems. Our work reports the synthesis of defect-engineered dendritic fibrous nanosilica (SiO x ) as an anode and commercial activated carbon (AC) as a cathode for the LICs. The Li/SiO x is prelithiated (Li x Si + Li2O) prior to the fabrication of the LIC for a few cycles and is then paired with the mass-balanced AC electrode to get AC/(Li x Si + Li2O)-based LIC assembly. Our LIC displays an excellent electrochemical performance with a maximum energy density of 169.7 Wh kg–1 at room temperature with ultralong durability of >48 000 cycles. The possibility of exploring LIC at different climatic conditions is also analyzed at various temperatures from −5 to 50 °C.
