“…Such electrodes must be free of dendrite formation, have long cycle life and withstand short-circuiting, have high electrical conductivity, excellent electrochemical stability, be cheap, safe, have a high charging rate, and low self-discharge. 12,13 The energy capacity of electrodes determines the amounts of ions the material can accommodate per gram of the material. Graphene, an excellent electrically conductive material, can host twice as many lithium-ions as compared to the conventional graphite electrode.…”

In this study, the benefits and challenges of existing energy storage systems are presented. The environmental threats and the apparent unreliability of fossil fuel energy sources necessitate the need for alternative sources of electrical power. Energy storage has been sourced from mechanical, electrical, thermal, chemical, and electrochemical systems. Perhaps, an electrochemical energy storage system, is a better option toward achieving a net zero carbon‐dioxide emission by 2050. Energy storage sources, such as: batteries and supercapacitors, can be reliably fabricated from the hybrid of polymers and two‐dimensional materials for electric vehicles, aviation, and grid load balancing applications. The performances of lithium‐ion batteries are yet to meet the requirements for high‐duty machines and devices. Graphite, the anode of lithium‐ion batteries, suffers from low capacity and high volume‐expansion, resulting in cracking and fracture of the electrodes. Herein, based on evidence from literature, this study suggests substituting graphite with polymer nanocomposite or metal‐oxide nanocomposites such as: conducting polymers, copper oxide, and graphene. This approach, giving attention to these materials' excellent electrochemical, thermal, electrical, mechanical, and redox properties, offers possible ways to overcome the limited limitations confronting lithium‐ion battery technology.

“…This project included the construction of a Li-ion battery system using an anode material consisting of reduced graphene oxide coated Fe 3 O 4 . When comparing the device to a system constructed entirely of pure Fe 3 O 4 or pure Fe 2 O 3 , it was revealed that the energy storage capacity and good durability of the device significantly increased [92][93][94][95][96][97][98][99][100].…”

A general rise in environmental and anthropogenically induced greenhouse gas emissions has resulted from worldwide population growth and a growing appetite for clean energy, industrial outputs, and consumer utilization. Furthermore, well-established, advanced, and emerging countries are seeking fossil fuel and petroleum resources to support their aviation, electric utilities, industrial sectors, and consumer processing essentials. There is an increasing tendency to overcome these challenging concerns and achieve the Paris Agreement’s priorities as emerging technological advances in clean energy technologies progress. Hydrogen is expected to be implemented in various production applications as a fundamental fuel in future energy carrier materials development and manufacturing processes. This paper summarizes recent developments and hydrogen technologies in fuel refining, hydrocarbon processing, materials manufacturing, pharmaceuticals, aircraft construction, electronics, and other hydrogen applications. It also highlights the existing industrialization scenario and describes prospective innovations, including theoretical scientific advancements, green raw materials production, potential exploration, and renewable resource integration. Moreover, this article further discusses some socioeconomic implications of hydrogen as a green resource.

The well-designed porous polypyrrole/dicarboxylic acid (PPy/DCA) (0.02) electrodes were successfully synthesized by hydrothermal method. In this study, the interesting structural properties of the synthesized electrodes were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TG-DTA), Brunauer–Emmett–Teller (BET) and scanning electron microscopy (SEM). The scanning electron microscopy results showed that a large number of random pores were formed on the electrode surface during the polymerization of pyrrole. The galvanostatic charge-discharge measurements exhibited a specific capacity of 854.2 F.g−1 at 2.7 A.g−1 with an energy density of 884.4 Wh.kg−1. Further, the supercapacitor electrode showed a good cycling test (87.3%) after 4000 cycles at a current density of 10.0 A.g−1 and wide operating voltage (3.0 V). Our studies suggest that 2,6-pyridinedicarboxylic acid doped-polypyrrole electrodes with interesting structure and easy synthesized method are promising candidates for high-performance supercapacitor devices.
