Abstract Biomass-activated carbon materials are promising electrode materials for lithium-ion hybrid capacitors (LiCs) because of their natural hierarchical pore structure. The efficient utilization of structural pores in activated carbon is very important for their electrochemical performance. Herein, porous biomass-activated carbon (PAC) with large specific surface area was prepared using a one-step activation method with biomass waste as the carbon source and ZnCl2 as the activator. To further improve its pore structure utilization efficiency, the PAC was doped with nitrogen using urea as the nitrogen source. The experimental results confirmed that PAC-1 with a high nitrogen doping level of 4.66% exhibited the most efficient pore utilization among all the samples investigated in this study. PAC-1 exhibited 92% capacity retention after 8000 cycles, showing good cycling stability. Then, to maximize the utilization of high-efficiency energy storage devices, LiNi0.8Co0.15Al0.05O2 (NCA), a promising cathode material for lithium-ion batteries with high specific capacity, was compounded with PAC-1 in different ratios to obtain NCA@PC composites. The NCA@PC-9 composite exhibited excellent capacitance in LiCs and an energy density of 210.9 Wh kg-1 at a high power density of 13.3 kW kg-1. These results provide guidelines for the design of high-performance and low-cost energy storage devices.

End Use

Renewable energy resources have been investigated as alternatives to fossil fuels. Though the energy density of these renewable sources is not comparable to the fossil fuels, their abundance make them highly interesting. There are three main steps in the renewable energy utilization: harvesting, conversion, and storage. Thus, after harvesting renewable energy, storing this energy is an important aspect for its large-scale end use. Considering the fact that the energy is a basic need for life on earth, there has been a strong scientific temperament towards the renewable energy utilization. The electrical energy storage maintains the key to promote the use of renewable energy. Among the storage devices, the rechargeable lithium ion batteries (LIBs) are the most promising energy storage devices. Among various cathodes proposed for LIBs, the most promising one is the spinel lithium manganese oxide (LiMn2O4). Its non-toxicity, low cost, abundance, and ease of synthesis, besides being environmentally friendly, make it suitable for next generation green LIBs.

The development of manganese dioxide (MnO[Formula: see text] as the cathode for aqueous Zn-MnO2 batteries is hindered by poor capacity. Herein, we propose a high-capacity MnO2 cathode constructed by engineering it with N-doping (N-MnO[Formula: see text] for a high-performance Zn-MnO2 battery. Benefiting from N element doping, the conductivity of N-MnO2 nanorods (NRs) electrode has been improved and the dissolution of the cathode during cycling can be relieved to some extent. The fabricated Zn-N-MnO2 battery based on the N-MnO2 cathode and a Zn foil anode presents an a real capacity of 0.31[Formula: see text]mAh[Formula: see text]cm[Formula: see text] at 2[Formula: see text]mA[Formula: see text]cm[Formula: see text], together with a remarkable energy density of 154.3[Formula: see text]Wh[Formula: see text]kg[Formula: see text] and a peak power density of 6914.7[Formula: see text]W[Formula: see text]kg[Formula: see text], substantially higher than most recently reported energy storage devices. The strategy of N doping can also bring intensive interest for other electrode materials for energy storage systems.

ABSTRACTWe report a simple approach to fabricate high performance energy storage devices based on aqueous inorganic ink comprised of hexagonal MnO2 nanosheets. The MnO2 ink exhibits long term stability. Continuous thin films can be formed on various substrates without using any binder. To obtain a flexible electrode for capacitive energy storage, we printed the MnO2 ink on commercially available A4 paper pre-treated by multi-walled carbon nanotubes. The electrode exhibited a maximum specific capacitance of 90.8 mF/cm2. The electrode could maintain 98.7% capacitance retention for 1,000 cycles at 10 mV/s. The MnO2 ink could be a potential candidate for large-scale production of flexible and printable electronic devices for energy storage and conversion.

Every electronic device required energy to operate. Most of the electronic devices are consume stored energy. Energy can be stored in the device like batteries, fuel cells, and capacitors. Elements of the periodic table are playing their role significantly in such energy storage devices. In this review article, different elements are reviewed with different methods that how efficiently these are working to make storage possible. An element like lithium in LIBs can be stored up to 4 volts of power which is the strongest behavior ever. It has earned huge attention in the commercial market all across. Carbon with nitrogen can give a high charge capacity of 487 mAh/g with retention of over 80%. So, it has high capacity load performance. Na-ion batteries are used for large-scale energy storage. These have up to 372 mAh/g storage capacity. K-ion batteries have fast ionic conductivity so these can have up to 710 mAh/g storage capacity.Ca-ion shows the impressive character toward its feature and gives storage upto 200 mAh/g. Cobalt batteries also show devoting behavior and can be stored up to a capacity 707 mAh/g at the current density of 90 mAh/g. Zn-ions show tremendous character in an aqueous medium. These batteries have a storage capacity of upto 810 mAh/g. Sulfur hybrid battery with lithium gives a reversible capacity of more than 900 mAh/g which is exceptional. All of these and more elements have very much promising behavior for storage with multiple cycles. This review article builds interest and trust in these elements.
