A system and method for separating battery components provides for the separation of batteries into their individual layers of anodes, cathodes, first polymer separator layers, and second polymer separator layers. A battery casing of a battery is cut to uncover a battery cell core, which is then washed to remove an electrolyte therefrom. An outer wrapping layer of the washed battery cell core is cut to form an open loose end, and the open loose end is engaged by first and second rollers to unroll a laminate therefrom. The laminate includes a cathode layer, an anode layer, a first polymer separator layer, and a second polymer separator layer. The laminate is then separated into the cathode layer, the anode layer, the first polymer separator layer, and the second polymer separator layer with the first roller, the second roller, a third roller, and a fourth roller. Each layer is then collected.

A box body includes a carrying plate configured to carry a battery and a one-way gravity valve disposed at the carrying plate. The one-way gravity valve is configured to be closed in response to a gravity of liquid in the box body being less than a threshold, and to be open in response to the gravity of the liquid in the box body reaching the threshold.

This application discloses a battery cabinet. A drain assembly is disposed at the bottom of a cabinet body of the battery cabinet. The drain assembly includes a drain valve. A valve spool and a magnetic object are disposed in the drain valve. The valve spool is movably disposed in the drain valve and has a first state of sealing the drain valve or a second state of opening the drain valve. The magnetic object generates a magnetic force to keep the valve spool in the first state, and the valve spool stays in the second state when a downward force applied to the valve spool is greater than a preset value. Therefore, draining is started when the water accumulated on the valve spool reaches a specified weight, and a new valve spool is automatically closed after the water is drained.

A portable power supply including a housing, at least one battery cell, a charger, and an attachment. The housing defines a cavity. The housing includes an upper portion, a lower portion, a plurality of air inlets defined in the lower portion, and a plurality of air outlets defined in the upper portion. The plurality of air inlets is in fluid communication with the cavity. The plurality of air outlets is in fluid communication with the cavity. The at least one battery cell is disposed in the cavity. The charger is electrically coupled with the battery cell. The attachment is coupled to the upper portion. The attachment is configured to at least partially cover each of the air outlets such that airflow exiting the air outlets travels a circuitous path.

A valve assembly includes a first part mountable to a fluid port of a panel and having a first opening for ingress of fluid into the first part from a first side of the panel, and a second opening for egress of fluid out of the first part through the fluid port to a second side of the panel; a second part within the first part for sealing the second opening when in a first position, a deformable member, and a resilient member biased to move the second part to a second position, to provide a fluid flow path from the first opening to the second. In an initial state, the deformable member retains the second part in the first position. Upon contacting liquid within the first part, at least part of the deformable member deforms to enable the resilient member to move the second part to the second position.
