Two‐Dimensional Siloxene–Graphene Heterostructure‐Based High‐Performance Supercapacitor for Capturing Regenerative Braking Energy in Electric Vehicles

Abstract

The development of high‐performance electrodes that increase the energy density of supercapacitors (SCs) (without compromising their power density) and have a wide temperature tolerance is crucial for the application of SCs in electric vehicles. Recent research has focused on the preparation of multicomponent materials to form electrodes with enhanced electrochemical properties. Herein, a siloxene–graphene (rGO) heterostructure electrode‐based symmetric SC (SSC) is designed that delivers a high energy density (55.79 Wh kg−1) and maximum power density of 15 000 W kg−1. The fabricated siloxene–rGO SSC can operate over a wide temperature range from –15 to 80 °C, which makes them suitable for applications in automobiles. This study shows the practical applicability of siloxene–rGO SSC to drive an electric car as well as to capture the braking energy in a regenerative brake‐electric vehicle prototype. This work opens new directions for evaluating the use of siloxene–rGO SSC as suitable energy devices in electric vehicles.

“…The global prevalence rates of subclinical (SCM) and clinical mastitis (CM) are 42 and 15%, respectively ( 51 ). The SCM prevalence was found to be higher when compared to CM prevalence in the countries of the World.…”

Ni(OH)2/NiSe Nanoparticles Supported on Carbon Microspheres for Long‐Life and High‐Performance Asymmetric Supercapacitors

“…[4] For example, Krishnamoorthy et al designed a siloxane-graphene heterostructure electrode-based symmetric SC, which had a high energy density and power density. [5] Particularly, it could operate over a wide temperature range from À 15 to 80 °C. Hence, their work opened a new direction for electric vehicles.…”

A novel method to synthesize BiSI uniformly coated with rGO by chemical bonding and its application as a supercapacitor electrode material

“…Reduced graphene oxide (rGO) is considered as one of the best carbon materials for it not only has good electrochemical performance, but also reduces the volume change and agglomeration of electrode materials. [32][33][34][35][36][37] Moreover, rGO itself can absorb ions in the electrolyte to form a double-layer capacitor and combined with a Bi-based active material can form an EDLC pseudo-capacitance composite capacitor. However, to date, the reported Bi-based materials and rGO composite materials, are physical mixtures, where rGO is physically adsorbed on the surface of the Bi-based material.…”
