A power plant system is provided having a high temperature battery, supplied with fluid via at least one supply line, for storing and releasing electrical energy, a gas turbine for generating electrical energy, and a heat exchanger which is designed to extract thermal energy from the exhaust stream of the gas turbine and transfer said thermal energy to the fluid, which fluid can be supplied after heat transfer to the high temperature battery via the at least one supply line.

A module battery is housed in a module battery housing rack. An electric cell is housed in a container. The container is provided with a high thermal conductive wall and a low thermal conductive wall. A first portion of a plate overlaps the outer surface of the high thermal conductive wall and a second portion of the plate protrudes from the outer surface. The second portion surrounds the first portion. A first main surface of the plate is brought into direct contact with the outer surface at the first portion and it is apart from the container at the second portion. A second main surface of the plate is exposed to a space, to which heat is allowed to radiate. An opening may or may not be formed at the first portion. A thermal conducting medium may be held between the first wall and the first portion.

A battery-pack case includes the following: a metal base; a container that has an opening in the top surface thereof, accommodates a battery pack, and is affixed to the metal base; a lid that closes the opening in the container; a positive-electrode bus bar and a negative-electrode bus bar provided on an exterior surface of the container, with a conductive member connected to each of the bus bars; and a plurality of wires that lead inside the container from the outside thereof. The wires are routed between the positive-electrode bus bar and the negative-electrode bus bar so as not to interfere with the aforementioned conductive members.

An electrochemical cell includes a positive electrode, a negative electrode, an electrolyte disposed between the positive electrode and the negative electrode, and an ion-conducting composite membrane disposed between the positive electrode and the negative electrode. The composite membrane includes a porous substrate having pores and a porosity from about 5 vol % to about 80 vol %, and a selective ion-conductive filler disposed at least partially within the pores. The filler includes an intercalation material. Methods of making the ion-conducting composite membrane and using an electrochemical cell having the ion-conducting composite membrane are also provided.

A sodium-sulfur battery includes a partition wall formed of a solid electrolyte, a cathode chamber formed on one of opposite sides of the partition wall, an anode chamber formed on another one of the opposite sides of the partition wall, sulfur accommodated in the cathode chamber, sodium some of which is accommodated in the anode chamber, a sodium container accommodating most of remaining sodium, and a communication passage communicating the anode chamber with the sodium container, and including a finely-perforated portion extending into the sodium container and opening inside the sodium container. Moreover, the communication passage further includes a shutoff portion for closing the communication passage itself.

Described herein is an electrochemical energy store including at least one electrochemical cell and a support structure, wherein the electrochemical cells are accommodated in a suspended manner in the support structure.

Disclosed herein is an electrochemical energy storage device including a plurality of electrochemical cells in a containing space in a housing. The electrochemical energy storage device includes a first duct that runs parallel to the top or the bottom of the housing and one or more heat transfer members that are arranged in spaces between the electrochemical cells, where at least one of the heat transfer members protrudes into the first duct.

An electrochemical storage device has an anode chamber filled with anode material during operation, and a cathode chamber filled with cathode material. The anode chamber is separated from the cathode chamber by solid body electrolyte guiding ions, and the anode chamber is limited on one side by the solid body electrolyte, on another side by a wall at least partially surrounding the solid body electrolyte. The wall is surrounded by a head part of the device, by a base part arranged opposite the head part and/or by a lateral part arranged between the head and base part. The wall has an electrical conductive wall section as an anode to the anode chamber, an at least partially flat, electrical conductive line section electrically connected to the wall section by a surface, and conductivity per surface of the line section greater than conductivity of the wall per surface of the wall section.

Sulfur containing nanoparticles that may be used within cathode electrodes within lithium ion batteries include in a first instance porous carbon shape materials (i.e., either nanoparticle shapes or bulk shapes that are subsequently ground to nanoparticle shapes) that are infused with a sulfur material. A synthetic route to these carbon and sulfur containing nanoparticles may use a template nanoparticle to form a hollow carbon shape shell, and subsequent dissolution of the template nanoparticle prior to infusion of the hollow carbon shape shell with a sulfur material. Sulfur infusion into other porous carbon shapes that are not hollow is also contemplated. A second type of sulfur containing nanoparticle includes a metal oxide material core upon which is located a shell layer that includes a vulcanized polymultiene polymer material and ion conducting polymer material. The foregoing sulfur containing nanoparticle materials provide the electrodes and lithium ion batteries with enhanced performance.

The invention relates to a method of storing, transporting and supplying electrochemical energy, with storage and supply being physically separated.
