    Abstract: An article of personal protective equipment (PPE) includes a battery, a charging circuit, and a controller. The battery is configured to power one or more components of the article of PPE. The charging circuit is configured to receive electrical power from a power supply and supply an electric current to the battery. The controller is configured to determine a plurality of thresholds of one or more electrical parameters of the battery. The plurality of thresholds has progressively increasing values. The controller is further configured to determine the one or more electrical parameters of the battery and control the charging circuit to progressively decrease a magnitude of the electric current supplied to the battery when the one or more electrical parameters progressively increase above each threshold from the plurality of thresholds.

    Abstract: There is provided a system having an electronic device powered by at least one battery, a controller communicably coupled to at least one battery, wherein the controller is configured to: determine a state of charge of the at least one battery; and interrupt a function of the electronic device for at least one predefined time period based on the state of charge of the at least one battery, where the interruption is indicative of a state of charge of the at least one battery. There is also provided an electronic device for use in the system.

    Abstract: High capacity lithium-ion electrochemical cells are provided that include positive electrode comprising a layered lithium transition metal oxide having a first irreversible capacity and a negative electrode that includes an alloy anode material that also has a first irreversible capacity. The first irreversible capacity of the positive electrode is less than the first irreversible capacity of the negative electrode. The discharge voltage curve of the positive electrode covers at least 10% of its capacity at voltages below 3.5 V ea) vs. Li/Li+. The average discharge voltage of the positive electrode is above 3.75 V vs. Li/Li+ when the cell is discharged from about 4.6 V vs. Li/Li+ to about 2.5 V vs. Li/Li+ at a rate of C/10 or slower and when the electrochemical cell is discharged to a final discharge voltage of about 2.5 V vs. Li/Li+ or greater.
