Abstract: Embodiments of the present application provide a battery cell, a battery, a power consumption device, and a method and device for producing a battery cell. The battery cell includes: a housing having an opening; an electrode assembly accommodated in the housing; an end cover configured to cover the opening and provided with an electrode terminal; and a support, disposed in the housing, where the support and the electrode assembly are arranged in a first direction, the support and the end cover are arranged in a second direction, and the first direction is perpendicular to the second direction, the support abuts against the electrode assembly in the first direction so as to limit the electrode assembly.

Abstract: A method for determining rock wettability based on contact angle measurement and correction of multiple oil globules includes: saturating a rock sample with oil, placing a shooting angle calibration circle on a measurement surface of the rock sample, and placing the rock sample saturated with oil in water for water imbibition and oil displacement to form a rock sample with multiple oil globules; acquiring an image of a measurement surface of the rock sample with multiple oil globules at a shooting angle ? and a deformation degree of the calibration circle in a shooting field of view, and calculating the shooting angle ?; correcting, based on the shooting angle ?, a contact angle measurement value ? through a contact angle correction model to acquire a contact angle correction value ?; and determining, based on the contact angle correction value ?, wettability of the rock sample.

Abstract: An air conditioner includes a housing, a compressor system provided in the housing and including a first heat exchanger, a second heat exchanger, a compressor, and a throttle device that are circularly communicated, and a liquid pump system provided in the housing and including a third heat exchanger, an energy storage device, and a liquid pump device that are circularly communicated. The liquid pump system contains a coolant circulating in the liquid pump system. The energy storage device includes an energy storage medium configured to receive energy from the second heat exchanger and store the energy, and to exchange heat with the coolant.
