Fabrication of high-performance dual carbon Li-ion hybrid capacitor: mass balancing approach to improve the energy-power density and cycle life
(Nature, 2020-07-02)
Most lithium-ion capacitor (LIC) devices include graphite or non-porous hard carbon as negative electrode often failing when demanding high energy at high power densities. Herein, we introduce a new LIC formed by the ...
Graphene as Vehicle for Ultrafast Lithium Ion Capacitor Development Based on Recycled Olive Pit Derived Carbons
(Electrochemical Society, 2019-08-21)
Herein we report a series of lithium ion capacitors (LICs) with extraordinary energy-to-power ratios based on olive pit recycled carbons and supported on graphene as a conducting matrix. LICs typically present limited ...
Natural and recyclable alginate hydrogels as extracting media for recovering valuable metals of spent lithium-ion batteries from a deep eutectic solvent
(Elsevier, 2023-09-07)
With the aim of achieving carbon neutrality, new policies to promote electric vehicle (EV) deployment have been announced in various countries. As EV sales gain market-share, the demand for batteries is growing very rapidly, ...
Highly packed graphene–CNT films as electrodes for aqueous supercapacitors with high volumetric performance
(Royal Society of Chemistry, 2018-01-24)
The increasing complexity of portable electronics demands the development of energy storage devices with higher volumetric energy and power densities. In this work we report a simple strategy for the preparation of partially ...
Reduced graphene oxide decorated with SnO2 nanoparticles as negative electrode for lithium ion capacitors
(Elsevier, 2018-07-25)
The effort to increase the energy density of conventional electric double-layer capacitors (EDLCs) goes through the development of lithium-ion capacitors (LICs). Herein, we report a self-standing, binder-free composite as ...
Recycling methods for different cathode chemistries – A critical review
(Elsevier, 2022-12)
Lithium-ion batteries (LIBs) have been gathering increasing attention worldwide as they are being widely used in portable devices and implemented in electric vehicles. With the increasing volume of LIBs poured into the ...
Na-Ion Batteries—Approaching Old and New Challenges
(Wiley, 2020-10-11)
The last 10 years established the beginning of a post-lithium era in the field of energy storage, with the renaissance of Na-ion batteries (NIBs) as alternative for Li-based systems. The development of this technology has ...
Sequential Fe Reduction, Involving Two Different Fe+ Intermediates, in the Conversion Reaction of Prussian Blue in Lithium-Ion Batteries
(ACS, 2022-05-11)
Ex situ X-ray absorption spectroscopy and in operando 57Fe-Mössbauer spectroscopy measurements are conducted to examine in detail the ongoing reaction mechanism of potassium Prussian blue (K-PB) within the narrow [1.6–0.005 ...
