Lithium ion batteries exhibit the highest energy densities of all battery types and are therefore an important technology for energy storage in every day life. Today's commercially available batteries employ organic polymer lithium conducting electrolytes, leading to multiple challenges and safety issues such as poor chemical stability, leakage and flammability. The next generation lithium ion ...

Although lithium ion batteries have gained commercial success owing to their high energy density, they lack suitable electrodes capable of rapid charging and discharging to enable a high power density critical for broad applications. Here, we demonstrate a simple bottom-up approach toward single crystalline vanadium oxide (VO2) ribbons with graphene layers. The unique structure of VO2-graphene ...

With the rapid growth in energy consumption, renewable is a promising solution. However, (e.g., wind, solar, and tidal) discontinuous irregular by nature, which poses new challenges to generation of large-scale storage devices. Rechargeable batteries using aqueous electrolyte multivalent ion charge are considered more suitable candidates compared lithium-ion lead-acid batteries, owing their low...

Secondary batteries have become important for smart grid and electric vehicle applications, and massive effort has been dedicated to optimizing the current generation and improving their energy density. Multi-electron chemistry has paved a new path for the breaking of the barriers that exist in traditional battery research and applications, and provided new ideas for developing new battery syst...

New applications such as hybrid electric vehicles and power backup require rechargeable batteries that combine high energy density with high charge and discharge rate capability. Using ab initio computational modeling, we identified useful strategies to design higher rate battery electrodes and tested them on lithium nickel manganese oxide [Li(Ni(0.5)Mn(0.5))O2], a safe, inexpensive material th...

1 Energy storage is an essential element of the complete landscape of energy processes, closely coupled with energy generation, transmission and usage. Development of lithium-based rechargeable batteries with higher energy density, lower costs and improved safety is highly desirable1–3. Over the past 25 years, lithiumion batteries based on conventional intercalation electrode materials have pla...

Lithium-ion batteries are the primary power source in electric vehicles, and the prognosis of their remaining useful life is vital for ensuring the safety, stability, and long lifetime of electric vehicles. Accurately establishing a mechanism model of a vehicle lithium-ion battery involves a complex electrochemical process. Remaining useful life (RUL) prognostics based on data-driven methods ha...
