A fire suppression system includes a battery enclosure, a liquid carbon dioxide (CO2) storage system, and a controller. The liquid CO2 storage system is fluidly coupled to the battery enclosure. The controller is configured to receive an indication of a fire condition associated with the battery enclosure. The controller is configured to control operation of the liquid CO2 storage system to provide liquid CO2 to an interior of the battery enclosure. The liquid CO2 converts into dry ice to cool the battery enclosure.

A battery module includes a cell stack including a plurality of battery cells stacked in a direction, a module housing having an internal space in which the cell stack is received and an air inlet and an air outlet through which air enters and exits, a valve installation hole formed through a side wall of the module housing, a feed valve nozzle installed at the valve installation hole facing the internal space of the module housing, and a water expandable member provided in the module housing. The water expandable member expands in volume when it absorbs water during operation of the feed valve nozzle to close at least one of the air inlet, the air outlet or the valve installation hole.

Embodiments of the invention relate to an open metal-air fuel cell system capable of uninterrupted supply power, which relates to the field of metal-air fuel cell stacks and comprises a sensing subsystem, a controller, a circulating filtration subsystem, an electrolyte solution tank and several open metal-air fuel cell units. Open metal-air fuel cell units are sequentially arranged within the electrolyte solution tank, and each open metal-air fuel cell unit is connected with each other in parallel. An air electrode of the open metal-air fuel cell unit has a tank structure, and the trough structure has a concave surface upwards. The sensing subsystem is arranged within the electrolyte tank. The electrolyte solution tank is connected with a circulating filtration subsystem. The controller is used for controlling a circulating flow of the circulating filtration subsystem depending on electrolyte solution temperature information collected by the sensing subsystem.

An electrochemical voltage source has an anode containing lithium, a cathode containing manganese oxide, and a housing. The cathode and the anode are arranged in an interior of the housing and are arranged opposite one another. An electrolyte reservoir in the form of a compressible storage body, which receives an electrolyte, is arranged between the anode and the cathode. The storage body has a first side resting against an end face of the cathode and a second side, which faces away from the first side, and rests against an end face of the anode. The cathode experiences an increase in volume when the voltage source is discharged. The anode experiences a decrease in volume during the discharge. During the discharge, the absolute value of the volume increase of the cathode is at least as great as the absolute value of the volume decrease of the anode.

A power storage device includes a power storage module, a pair of current collector plates configured to be stacked to interpose the power storage module in a first direction that is vertical, a pair of insulating plates configured to be stacked to interpose the power storage module and the pair of current collector plates in the first direction; and a pair of restraint plates configured to be stacked to interpose the power storage module, the pair of current collector plates, and the pair of insulating plates in the first direction. The power storage module is configured to include an accommodation space that accommodates an electrolytic solution together with a power generation element. A pressure adjustment valve communicating with the accommodation space is provided on a side surface of the power storage module. The insulating plate arranged on a lower side in the first direction with respect to the power storage module is configured to include a main body portion arranged between the current collector plate and the restraint plate, and a liquid receiving portion that is provided on an outer edge portion of the main body portion, is arranged at least at a position corresponding to the pressure adjustment valve when viewed from the first direction, and stores the electrolytic solution discharged from the power storage module. The main body portion and the liquid receiving portion are integrally formed.
