    Abstract: A method for detecting a failure mode in an electronic selector having a button coupled to a first switch, a second switch, and a third switch, the method includes incrementing a button activation counter once for each button activation event and incrementing a first switch-closed counter, a second switch-closed counter, and a third switch-closed counter once for each button activation event if the respective switch is closed at any time during the button activation event. The method further includes incrementing a first switch-opened counter, a second switch-opened counter, and a third switch-opened counter once for each button activation event. The method further includes evaluating a fault status of the first switch, the second switch, or the third switch when the button activation counter reaches or exceeds a predetermined threshold; and reporting the fault status of the first switch, the second switch or the third switch.

    Abstract: An electrode material for use in an electrochemical cell, like a lithium-ion battery, is provided. The electrode material may be a negative electrode comprising graphite, silicon, silicon-alloys, or tin-alloys, for example. By avoiding deposition of transition metals, the battery substantially avoids charge capacity fade during operation. The surface coating is particularly useful with negative electrodes to minimize or prevent deposition of transition metals thereon in the electrochemical cell. The coating has a thickness of less than or equal to about 40 nm. Methods for making such materials and using such coatings to minimize transition metal deposition in electrochemical cells are likewise provided.

    Abstract: A lithium-ion cell has a positive electrode comprising at least one active material comprising a lithium transition metal compound in a binder comprising at least one binder material with functional groups selected from alkali and alkaline earth salts of acid groups and hydroxyl groups, amine groups, isocyanate groups, urethane groups, urea groups, amide groups, and combinations of these; a negative electrode comprising metallic lithium or a lithium host material with appropriately low operation voltage vs. metallic lithium; a nonaqueous solution of a lithium salt; and an electrically nonconductive, ion-pervious separator positioned between the electrodes.
