Abstract: The present application relates to the field of battery technologies, for example, to a battery, a battery module, and a battery pack. The battery includes a housing, a terminal pole column, and an upper plastic member. A first through hole is defined on a top cover of the housing. The terminal pole column passes through the first through hole. The upper plastic member is disposed above the top cover of the housing. The terminal pole column is capable of passing through the upper plastic member and bending outward to form a flange, and the terminal pole column abuts against the upper plastic member, and an upper top surface of the terminal pole column and an upper top surface of the upper plastic member are flush with each other.

Abstract: Provided are a security apparatus, a manufacturing method thereof, and a battery. A first score-line and a second score-line are disposed on the security apparatus. The first score-line and the second score-line are connected to form a closed line. The first score-line and the second score-line divide the security apparatus into an outer frame and a valve sheet. A thickness of the security apparatus at the second score-line is greater than a thickness of the security apparatus at the first score-line. The valve sheet is capable of being separated from the outer frame along the first score-line and being kept in connection with the outer frame at the second score-line.

Abstract: A microdomained aqueous emulsion polymer is provided. The polymer comprises a first domain having a Tg of from ?80 to ?10° C. and comprising from 80 to 100 wt % of acrylic monomer; and a non-crosslinked second domain having a Tg of from 50 to 120° C. and comprising, as polymerized unit and based on the weight of the second domain, from 50 to 100 wt % of styrenic monomer; wherein the content of the second domain ranges from greater than 6 wt % to 30 wt % of the total weight of the first domain and the second domain. The polymer is suitable for applications including adhesives and binders, especially for pressure sensitive adhesives.
