The morphological characteristics of a nanomaterial, i.e., geometric shape and dimension, and the arrangement of atoms, which both vary depending on specific nanostructures, have a considerable impact on properties such as electronic structure, ionic diffusion, and surface structure. It is, therefore, essential to det…
As the commercial market is perpetually asking for smaller and lighter batteries, energy density (both gravimetric and volumetric) had become a very important criterion to select a cathode material for both automotive and mobile application. Nowadays, one of the most effective ways to elevate energy density is to rais…
Electrolyte decomposition and the formation of the solid-electrolyte interface SEI depends critically on the used active materials, electrolytes or electrolyte additives. A better knowledge of the initial steps of SEI formation is thus necessary to cope with new active anode materials or new electrolytes. The initial…
Introduction The biggest challenge in the non-aqueous Li-O2 system is the extremely large overpotential. The total polarization between discharging and charging process reaches >0.5 V, even in the case of best one ever reported1. An approach for the improvement in the power density of the Li-O2 battery is utilization…
Employing energy from renewable sources, such as solar and wind, will become increasingly important for sustainable development.1 Organic rechargeable batteries (ORBs) have been receiving a significant amount of attention in the literature for their versatile molecular structure design, sustainability, flexibility and…
There are intensive research activities for alternative electrode materials in the next generation of rechargeable lithium ion batteries, particularly for those used in hybrid and pure electric vehicles. Phosphate-based cathode materials have been a considerable investigation due to its attractive properties (low-cost…
Lithium sulfur (Li-S) batteries have become a popular focus of energy storage research due to their high theoretical energy density and the economic viability. The primary issues that Li-S batteries face stem from the high solubility of lithium polysulfide reaction intermediates (e.g. Li2Sx, 2 ≤ x ≤ 8) formed during t…
The increase in the demand for clean and sustainable energy has prompted intense effort towards the realization of high-performance energy storage technologies. Among the many available energy storage technologies, lithium(Li)-ion batteries with Li-intercalation compounds as positive electrodes have achieved great suc…
Mesoporous hollow nanostructures have been attracting remarkable attention because of their high surface area, robust structure and are indispensably have a great scope for basic studies. On the other side, binary metal oxides are considered to be as promising anode materials for lithium ion batteries, especially, NiC…
Exchanging the active specie, Li+ in Li-ion batteries by multivalent, abundant and cheap cations, such as Mg2+, are projected to boost the energy density and lower the cost per kilo-watt-hour significantly, making the Mg-ion battery technology a promising candidate for one of the battery technologies of the future.1,2…
Cubic garnet phases based on Al-substituted Li7La3Zr2O12 (LLZO) exhibit superior ionic conductivity and outstanding electrochemical stability against metallic lithium anode, making them promising solid electrolyte for next-generation rechargeable battery systems. However, high interfacial impedances of LLZO have preve…
Rechargeable magnesium battery can be a candidate of the next-generation batteries because magnesium has a higher volumetric capacity, is more abundant in terms of the resources, and is less reactive in air than lithium. We previously found that a redox-active organic compound, 2,5-dimethoxy-1,4-benzoquinone (DMBQ),…
Both, chemical composition and microstructure characteristics control the performance of electrodes for batteries. High-power and high-energy lithium ion batteries are composed of electrodes with similar or different chemical composition, but are always distinguishable by their electrode microstructure characteristics…
The identification of energy storage systems alternatives to lithium-based technologies is now seen as a valid step for the development of economically sustainable secondary batteries.[1] Among these, sodium-based batteries appear as very promising candidates due to the low cost and high abundance of sodium. In additi…
Graphitic carbon is extensively used as anode material in most of the commercial lithium-ion batteries due to its low cost and high coulombic efficiency. However, capacity of carbon anode (372mAh/g and 830mAh/mL) is limited by the reversible electrochemical intercalation of lithium ions in its structure. So, alternati…
In this work, we demonstrate the use of M13 virus to produce metal nanofoams that can be used as current collectors in lithium ion battery electrodes. Metal foam current collectors have been demonstrated to promote rapid electronic conduction in battery electrodes while maintaining a high active material mass fraction…
Of the three categories of cathode materials that dominate today’s lithium-ion battery industry, i.e., those with layered, spinel and olivine-type structures, layered lithium-metal-oxide systems remain the most attractive category for providing high energy densities. Although LiCoO2 (LCO) and LiNi0.8Co0.15Al0.05O2 (NC…
With an ever-expanding application of energy storage systems, lithium-ion batteries (LIBs) have attracted a significant scientific and industrial attention during last decades. However, the current LIBs based on lithium metal oxides or phosphate cathodes and graphitic carbon anodes have intrinsic limitation in energy…
Olivine-type LiFePO4 is considered as a promising cathode material for high power density lithium-ion battery. Lithium-ion intercalation proceeds thorough a two-phase reaction divided into LiFePO4 and FePO4. During the phase transition between LiFePO4 and FePO4, the nucleation of a new phase occurs at the electrode /…
Battery based energy storage is expected to play a vital enabling role in future energy supply and demand. In particular, it is likely that storage of electricity generated from major renewable energy sources (such as solar, wind, or wave power) will be an important component of future energy portfolios worldwide.
