Study of Volumetrically Heated Ultra-High Energy Density Plasmas

open access: green, 2016
Heating dense matter to millions of degrees is important for applications, but requires complex and expensive methods. The major goal of the project was to demonstrate using a compact laser the creation of a new ultra-high energy density plasma regime characterized by simultaneous extremely high temperature and high density, and to study it combining ...

Cell Design Considerations and Impact on Energy Density—A Practical Approach to EV Cell Design

open access: yesWorld Electric Vehicle Journal, 2023
Higher-energy-density, Wh L−1 or Wh kg−1, lithium-ion cells are one of the critical advancements required for the implementation of electric vehicles. This increase leads to a longer drive distance between recharges. Aside from material development, full

Graphene balls for lithium rechargeable batteries with fast charging and high volumetric energy densities [PDF]

open access: goldNature Communications, 2017
AbstractImproving one property without sacrificing others is challenging for lithium-ion batteries due to the trade-off nature among key parameters. Here we report a chemical vapor deposition process to grow a graphene–silica assembly, called a graphene ball. Its hierarchical three-dimensional structure with the silicon oxide nanoparticle center allows

Flexible Aqueous Lithium‐Ion Battery with High Safety and Large Volumetric Energy Density [PDF]

open access: bronzeAngewandte Chemie, 2016
AbstractA flexible and wearable aqueous lithium‐ion battery is introduced based on spinel Li1.1Mn2O4 cathode and a carbon‐coated NASICON‐type LiTi2(PO4)3 anode (NASICON=sodium‐ion super ionic conductor). Energy densities of 63 Wh kg−1 or 124 mWh cm−3 and power densities of 3 275 W kg−1 or 11.1 W cm−3 can be obtained, which are seven times larger than ...
