Electrode assembly with separated support tapes in secondary battery

Separated support tapes are attached to an electrode assembly which includes a negative electrode plate, a positive electrode plate, and a separator for performing charge and discharge operations. The separated support tapes are attached to a lower portion of the electrode assembly so as to allow the electrode assembly to be easily inserted into a can, while reducing the possibility of fire in a secondary battery caused by a hard short when the secondary battery is compressed due to external force applied thereto, preventing battery performance from being deteriorated by allowing electrolyte to sufficiently flow into a lower portion of the electrode assembly, and reducing a manufacturing cost of the secondary battery by minimizing the amount of separated support tape to be used.

Heat-wrapped air-impact flame-retardant cable

The invention discloses a heat-wrapped air-impact flame-retardant cable, belongs to the technical field of cables, and provides a heat-wrapped air-impact flame-retardant cable which can promote flame-retardant mixed powder in a storage cavity to be heated and decomposed through the temperature during combustion and can promote a hot soft guide rope to be softened by means of temperature change. Therefore, under the mutual attraction effect of the two magnetic adsorption balls, the external thermal change flame-retardant films are dragged to get close to each other until the external thermal change flame-retardant films wrap the whole cable body, and the external thermal change flame-retardant films can be punctured by means of the first puncture short needles when the external thermal change flame-retardant films make contact with each other. Therefore, carbon dioxide gas and water generated through decomposition of the flame-retardant mixed powder can be promoted to flow out. On one hand, the possibility of combustion of the cable body can be reduced by virtue of the flame-retardant effect of carbon dioxide, and on the other hand, the generated water enters the space between the cable body and the external thermal change flame-retardant film, so that the cable body can be protected, and the possibility of damage caused by over-high temperature of the cable body is reduced.
