摘要： The invention provides a method for suppressing thermal runaway of lithium batteries, which is included a step of providing a lithium battery capable of performing charging and discharging, which includes an electrochemical reaction system. When the temperature of the lithium battery reaches to a predetermined temperature, a metal ion (A) and an amphoteric metal ion (B) are applied to the positive active material layer and the negative active material layer of the lithium battery to passivate the positive active material layer and the negative active material layer. The metal ion (A) is selected from a non-lithium alkali metal ion, an alkaline earth metal ion or a combination thereof to prevent the thermal runaway from occurring.

摘要： A cabinet with anti-condensation mechanism is used to control opening and closing a cabinet door of the cabinet. The cabinet includes a control module, a temperature control module, and a locking module. The control module senses a cabinet-inside temperature inside the cabinet, and senses cabinet-outside temperature and a cabinet-outside humidity outside the cabinet to generate a dew-point threshold value. The temperature control module is used to adjust the cabinet-inside temperature. The locking module is used to lock the cabinet door or unlock the cabinet door. The control module controls the locking module according to the cabinet-inside temperature and the dew-point threshold value, and controls the temperature control module to adjust the cabinet-inside temperature to be greater than or equal to the dew-point threshold value when the control module receives a trigger signal.

摘要： An insertion device includes an elongate member and a stylet. The elongate member has a proximal end portion, a distal end portion, and defines a lumen therethrough. The stylet has a proximal end portion, a distal end portion, and is slidably coupled to the elongate member. The stylet is configured to move from a first position to a second position with respect to the elongate member. The proximal end portion of the stylet is configured to removably couple a mesh carrier thereto. A portion of the proximal end portion of the stylet is disposed outside of the lumen of the elongate member when the stylet is in its first position and is disposed within the lumen when the stylet is in its second position.
