Electrochemical systems for mitigating or reducing the release of undesirable by-products of electrochemical cells are provided. These systems may be particularly relevant to the sequestering of hydrogen sulfide gas in solid state electrochemical cells with sulfide-based electrolytes. Some of the systems include an integrated hydrogen sulfide eliminating layer or microspheres containing a hydrogen sulfide eliminating material adjacent to one or more electrochemical cells and within a containment structure.

A marine battery system configured to provide energy to a marine vessel load is provided. The marine battery system includes a main enclosure body and an auxiliary enclosure body that is detachably coupled to the main enclosure body to define a sealed battery volume. The auxiliary enclosure body is configured to perform a pressure accommodation action responsive to an increase in a temperature within the sealed battery volume. The marine battery system further includes a battery disposed within the sealed battery volume.

A tank includes a plurality of independent accommodation cavities. Each of the accommodation cavities includes a corresponding fragile structure, and the fragile structures possess different packaging strengths.

An assembly for a vehicle comprising at least two battery blocks, each having a casing in which the battery block is enclosed and that has a connection face. The outer skin of the vehicle has an outlet orifice. There is a main duct connected to the outlet orifice. For each casing, an evacuation duct is connected between the connection face and the main duct. A damping unit is provided at the joint between each connection face and the evacuation duct. A damping unit is provided at the joint between the main duct and the outlet orifice. Each damping unit limits the amplitude of an overpressure propagating from the casing towards the outlet orifice. Such an assembly enables an overpressure to be damped in the event of a battery being damaged, inter alia.
