摘要： A battery-powered system includes a battery pack (10; 71; 81) connected to an electrical equipment (30; 50; 76; 86). The battery pack includes a first positive electrode terminal (11), a first negative electrode terminal (12), a first communication terminal (13), a first data input circuit (23), and a first limiting circuit (D11; D72; D82) that limits a flow of electric current in a direction from the first negative electrode terminal to the first communication terminal via the first data input circuit. The connected equipment includes a second positive electrode terminal (31; 51), a second negative electrode terminal (32; 52), a second communication terminal (33; 53), a second data input circuit (43; 63; 77; 87), and a second limiting circuit (D31; D51; D77; D87) that limits a flow of electric current in a direction from the second negative electrode terminal to the second communication terminal via the second data input circuit.

The powder laminate has a positive electrode powder layer, a negative powder layer, a solid electrolyte layer disposed between the positive electrode powder layer and the negative electrode powder layer, and an absorption layer covering an outer periphery of the positive electrode powder layer or the negative electrode powder layer. The absorption layer includes at least one of a hydrogen sulfide adsorption layer and a moisture adsorption layer. The powder laminate comprises a peripheral edge part and a center part surrounded by the peripheral edge part. A thickness of the peripheral edge part of the powder laminate is greater than a thickness of the center part of the powder laminate.

摘要： One or more external connectors of a conformal wearable battery (CWB) may be controlled to reduce a voltage potential supplied to the connectors when exposed to a conductive liquid. The connectors may be uniform serial bus (USB) connectors or other connectors. One or more unused terminals of the one or more connectors may be pulled to a voltage potential and then monitored for a change in voltage. When the change in voltage satisfies a voltage threshold, the voltage potential supplied to the one or more connectors may be reduced and/or interrupted. The change in voltage may be evaluated against the voltage threshold alone or may be evaluated against the voltage threshold and a time threshold relating to a time after the voltage satisfied the voltage threshold. The voltage of the monitored terminal may be evaluated against one or more voltage thresholds and/or one or more time thresholds. Based on the voltage threshold having been met, the voltage supplied to the connector may be reduced or stopped.

摘要： The present invention relates to a secondary battery capable of improving venting pressure distribution. A secondary battery including an electrode assembly, a can member that accommodates the electrode assembly, and a top cap assembly that covers an opening of the can member. The top cap assembly includes a top cap positioned at the uppermost portion and a safety vent part positioned below the top cap. The safety vent part includes a rupture portion that is ruptured when an internal pressure within the can member equals or exceeds a predetermined pressure, a rupture notch portion that defines a boundary of the rupture portion, and a bending notch portion which is spaced apart from the rupture notch portion toward a center of the rupture portion on a bottom surface of the rupture portion, and the bending notch portion is bent when the internal pressure within the can member increases.

摘要： A portable power source. The portable power source includes a housing, a first battery pack support configured to receive a first removable and rechargeable battery pack, a second battery pack support configured to receive a second removable and rechargeable battery pack, an inverter within the housing, and an alternating current power outlet. The inverter is configured to receive output power from the first removable and rechargeable battery pack and the second removable and rechargeable battery pack. The inverter is configured to produce an alternating current power output. The alternating current power outlet is configured to receive the alternating current power output from the inverter. The inverter is configured to be disabled when the first removable and rechargeable battery pack is received in the first battery pack support and the second removable and rechargeable battery pack is not received in the second battery pack support.
