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.

Solid Oxide Electrolysis

Renewable energy resources such as solar energy, wind energy, hydropower or geothermal energy have attracted significant attention in recent years. Renewable energy sources have to match supply with demand, therefore it is essential that energy storage devices (e.g., secondary batteries) are developed. However, secondary batteries are accompanied with critical problems such as high cost for the limited energy storage capacity and loss of charge over time. Energy storage in the form of chemical species, such as H2 or CO2, have no constraints on energy storage capacity and will also be essential. When plentiful renewable energy exists, for example, it could be used to convert H2O into hydrogen via water electrolysis. Also, renewable energy resources could be used to reduce CO2 into CO and recycle CO2 and H2O into sustainable hydrocarbon fuels in solid oxide electrolysis (SOE).

<p></p><p>Porous carbon has attracted extensive attentions as the electrode material for various energy storage devices considering its advantages like high theoretical capacitance/capacity, high conductivity, low cost and earth abundant inherence. However, there still exists some disadvantages limiting its further applications, such as the tedious fabrication process, limited metal-ion transport kinetics and undesired structure deformation at harsh electrochemical conditions. Herein, we report a facile strategy, with calcium gluconate firstly reported as the carbon source, to fabricate ultrathin porous carbon nanosheets. <a>The as-prepared Ca-900 electrode delivers excellent K-ion storage performance including high reversible capacity (430.7 mAh g<sup>-1</sup>), superior rate capability (154.8 mAh g<sup>-1</sup> at an ultrahigh current density of 5.0 A g<sup>-1</sup>) and ultra-stable long-term cycling stability (a high capacity retention ratio of ~81.2% after 4000 cycles at 1.0 A g<sup>-1</sup>). </a>Similarly, when being applied in Zn-ion capacitors, the Ca-900 electrode also exhibits an ultra-stable cycling performance with ~90.9% capacity retention after 4000 cycles at 1.0 A g<sup>-1</sup>, illuminating the applicable potentials. Moreover, the origin of the fast and smooth metal-ion storage is also revealed by carefully designed consecutive CV measurements. Overall, considering the facile preparation strategy, unique structure, application flexibility and in-depth mechanism investigations, this work will deepen the fundamental understandings and boost the commercialization of high-efficient energy storage devices like potassium-ion/sodium-ion batteries, zinc-ion batteries/capacitors and aluminum-ion batteries.</p><br><p></p>
