A method of manufacturing a battery includes introducing a first material to the battery, providing an anode, a cathode and a separator of the battery; and assembling the anode, the separator and the cathode. The first material is configured and arranged to increase the internal impedance of the battery upon mechanical or thermal loading.

The disclosure features methods of forming composite materials, and the composite materials formed by such methods. The methods include forming a mixture that includes a binder material and a filler material, and applying a pressure of at least 10 MPa to the mixture to form the composite material, where the composite material thus formed includes less than 9% by weight of the binder material, less than 18% by volume of the binder material, or both, and has a flexural strength of at least 3 MPa.

Structural composite materials

A battery system includes a load bearing structure having battery cells, or structures formed by battery cells, and at least one mechanical switch, and an electrical connection coupled with the battery cells of the load bearing structure. A battery has a rate-sensitive component that is configured to deform into a first state to provide a first reaction force under a mechanical loading of a first magnitude. The rate-sensitive component is configured to deform into a second state to provide a second reaction force under a mechanical loading of a second magnitude.

Rate-sensitive and self-releasing battery cells and battery-cell structures as structural and/or energy-absorbing vehicle components

The present invention relates to volume and/or shape memory systems for which the volume and/or shape can be adjusted by controlling one or more variables such as applied voltage and temperature. In one embodiment, the volume and/or shape memory systems of the present invention are controlled and/or adjusted by way of a temperature mechanism. In another embodiment, the volume and/or shape memory systems of the present invention are controlled and/or adjusted by way of a voltage mechanism. In still another embodiment, the present invention provides a device that contains, in part, a smart volume and/or shape memory material that exhibits high energy densities, and can provide large displacements over broad temperature and/or voltage ranges.

Nanoporous materials for use in intelligent systems

The present invention is directed to an energy absorption system for absorbing mechanical impact energy using one or more chemicals for promoting absorption of a liquid, and optionally including one or more promoter, recovery agent, and/or viscosity adjusting agent, which allows the system to release the absorbed energy.

Use of chemical admixtures as promotors, recovery agents

A kinetic energy and blast energy absorbing material includes: a micro-truss structure including: a plurality of first struts extending along a first direction; a plurality of second struts extending along a second direction; and a plurality of third struts extending along a third direction; and a compressible fluid comprising a liquid or gel and a nanoporous material, wherein the micro-truss structure contains the compressible fluid.
