This patent application is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "The present disclosure relates generally to energy storage devices, and more particularly to metal-ion battery technology and the like.
"Owing in part to their relatively high energy densities, light weight, and potential for long lifetimes, advanced metal-ion batteries such as lithium-ion (Li-ion) batteries are desirable for a wide range of consumer electronics. However, despite their increasing commercial prevalence, further development of these batteries is needed, particularly for potential applications in low- or zero-emission hybrid-electrical or fully-electrical vehicles, consumer electronics, energy-efficient cargo ships and locomotives, aerospace applications, and power grids.
"Accordingly, there remains a need for improved batteries, components, and other related materials and manufacturing processes."
In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "Embodiments disclosed herein address the above stated needs by providing improved battery components, improved batteries made therefrom, and methods of making and using the same.
"According to various embodiments, various battery electrode compositions are provided comprising core-shell composites. Each of the composites may comprise, for example, an active material, a collapsible core, and a shell. The active material may be provided to store and release metal ions during battery operation, whereby the storing and releasing of the metal ions causes a substantial change in volume of the active material. The collapsible core may be disposed in combination with the active material to accommodate the changes in volume. The shell may at least partially encase the active material and the core, the shell being formed from a material that is substantially permeable to the metal ions stored and released by the active material.
