摘要： A thermal management assembly comprises an electrochemical cell, a heat sink, and a thermal pathway comprising a thermally interruptible interface interposed therebetween the electrochemical cell and the heat sink. The thermal pathway comprises an expandable material comprising intumescent particles. If heated to at least a first onset temperature, the expandable material expands and causes at least partial shear delamination at the first thermally interruptible interface. A composite thermal management article comprises a first layer comprising an expandable material comprising intumescent particles and a second layer comprising a thermal conductor material. The first and second layers contact each other at a thermally interruptible interface.

摘要： Method for active battery management to optimize battery performance. The method includes providing signal injections for charging and discharging of a battery. The signal injections include various charging and discharging profiles, rates, and endpoints. Response signals corresponding with the signal injections are received, and a utility of those signals is measured. Based upon the utility of the response signals, data relating to charging and discharging of the battery is modified to optimize battery performance and to determine when to discharge the battery into a power grid in order to return power to the grid in exchange for an economic benefit such as a payment or rebate from a utility company.

摘要： A method may determine a remaining capacity of a cell that includes a lithium-alloying material in an electrode using a controller. The method includes receiving a temperature signal representing a temperature of a partially discharged cell and receiving a voltage signal representing a voltage of the partially discharged cell. The method further includes determining a time-dependent fade component and a cycle-dependent fade component of the cell. The time-dependent fade component of the cell is determined based on the temperature, the voltage, and an operating time of the cell. The cycle-dependent fade component of the cell is determined based on a depth of discharge of the partially discharged cell and cycle count data representing cycle-dependent fade from previous cycles of the cell. The method further includes determining a remaining capacity of the cell based on the time-dependent fade component, the cycle-dependent fade component, and a reference capacity of the cell.

摘要： Polymer matrix composite comprising a porous polymeric network; and a plurality of intumescent particles distributed within the polymeric network structure; wherein the intumescent particles are present in a range from 15 to 99 weight percent, based on the total weight of the intumescent particles and the polymer (excluding the solvent); and wherein the polymer matrix composite volumetrically expands at least 2 times its initial volume when exposed to at least one temperature greater than 135° C.; and methods for making the same. The polymer matrix composites are useful, for example, as fillers, thermally initiated fuses, and fire stop devices.
