Dual-Energy CT-based Opportunistic Volumetric Bone Mineral Density Assessment of the Distal Radius
Radiology, 2023Background In patients with distal radius fractures (DRFs), low bone mineral density (BMD) is associated with bone substitute use during surgery and bone nonunion, but BMD information is not regularly available. Purpose To evaluate the feasibility of dual-energy CT (DECT)-based BMD assessment from routine examinations in the distal radius and the ...

Superior Long-Term Energy Retention and Volumetric Energy Density for Li-Rich Cathode Materials
Nano Letters, 2014Li-rich materials are considered the most promising for Li-ion battery cathodes, as high energy densities can be achieved. However, because an activation method is lacking for large particles, small particles must be used with large surface areas, a critical drawback that leads to poor long-term energy retention and low volumetric energy densities ...

High Volumetric Energy Density Hybrid Supercapacitors Based on Reduced Graphene Oxide Scrolls
ACS Applied Materials & Interfaces, 2017The low volumetric energy density of reduced graphene oxide (rGO)-based electrodes limits its application in commercial electrochemical energy storage devices that require high-performance energy storage capacities in small volumes. The volumetric energy density of rGO-based electrode materials is very low due to their low packing density.

ACS Applied Materials & Interfaces, 2018
Micro-supercapacitors (MSCs) are attractive for applications in next-generation mobile and wearable devices and have the potential to complement or even replace lithium batteries. However, many previous MSCs have often exhibited a low volumetric energy density with high-loading electrodes because of the nonuniform pore structure of the electrodes.

A Better Choice to Achieve High Volumetric Energy Density: Anode‐Free Lithium‐Metal Batteries
Advanced Materials, 2022AbstractVolumetric energy density is a critical but easily neglected index of lithium‐metal batteries (LMBs). Compared with gravimetric energy density, the volumetric energy density (VED) of LMBs is much more sensitive to the anode/cathode (A/C) ratio due to the low density of lithium (Li) metal and the volume expansion of the Li‐metal anode owing to ...
