An electricity storage system is provided that includes a plurality of cartridges connected together in parallel, each cartridge comprising a plurality of cells connected together, where each of the plurality of cartridges independently maintains a voltage convertible to a commercial voltage. The electricity storage system is configured to, upon receipt of a cartridge withdrawal signal input by a user and indicating a user's intention to withdraw any cartridge of the plurality of cartridges regardless of the operational state of a selected cartridge, including whether the selected cartridge is charging or discharging, disallow conductions with respect to the cartridge to be withdrawn and output a signal indicating that the selected cartridge is ready to be withdrawn.

Electricity storage system and cartridge

A sheet-laminated lithium ion secondary battery comprising: a membrane electrode assembly which comprises a cathode sheet comprising a cathode current collector having formed thereon a cathode active material layer, and an anode sheet comprising an anode current collector having formed thereon an anode active material layer, the cathode sheet and the anode sheet being laminated through a separator; and a sheet outer casing having accommodated therein the membrane electrode assembly, wherein, in the membrane electrode assembly, a sheet thermoplastic resin layer is inserted as at least one of an interlayer between the cathode sheet and the separator, and an interlayer between the anode sheet and the separator.

Sheet-laminated lithium ion secondary battery and production method for sheet-laminated lithium ion secondary battery

An electricity storage system comprising: a plurality of cartridges connected together in parallel, each cartridge comprising a plurality of cells connected together, and a circuit for preventing cross current, which restricts the current in each cartridge so as to cause the current to flow in one direction selected from a discharge direction and a charge direction, wherein said cartridges connected together in parallel are simultaneously charged with a direct current voltage converted from a commercial voltage, or said cartridges connected together in parallel are caused to discharge simultaneously so that said electricity storage system outputs a commercial voltage.

A method for producing a laminate battery includes: forming a membrane electrode assembly having a multilayer structure including a positive electrode plate, a negative electrode plate and an electrolyte layer, the electrolyte layer being provided between the positive electrode plate and the negative electrode plate, a tab attachment step including joining terminal tabs to end portions of the positive electrode plate and the negative electrode plate of the membrane electrode assembly on an outer packaging material, and covering the membrane electrode assembly with the outer packaging material. Each terminal tab is joined by bending at least a part of the end portion of the outer packaging material in a direction opposite to the membrane electrode assembly, and then joining the terminal tab to the positive electrode plate or the negative electrode plate at a portion corresponding to the bent part of the end portion of the outer packaging material.

Method for producing laminate battery, apparatus for producing laminate battery, and laminate battery

A blow-off partis provided with a blow-off port' which is dimensioned small enough so as not to allow a blow-off stream to be blown off directly to a part of a wafer W which part is located at the more internal side of the wafer than the outer edge of the wafer W and not to be subjected to plasmatizing process. A suction partis provided with a suction portA in associating with the blow-off partThe suction portA is disposed proximate to the blow-off port&#x2032; and forms a suction stream oriented generally in the reverse direction with respect to the blow-off stream.

Plasma processing apparatus and method thereof

A nozzle head NH of a plasma processing apparatus comprises an annular inner holder, an annular inner electrodesurrounding this holder, an annular outer electrodesurrounding this electrode, and an annular outer holdersurrounding this electrode. The inner holderis provided with a plurality of boltsspacedly arranged in the peripheral direction and adapted to push the inner electroderadially outwardly. The outer holderis provided with a plurality of boltsspacedly arranged in the peripheral direction and adapted to push the outer electroderadially inwardly.

Composite high-pressure tube and method of manufacturing the tube

As the first object, the present invention intends to provide high-pressure composite pipes which show remarkable pressure resistance and optimum applicability in various uses and which can be economically manufactured in a light weight. To achieve this object, a high-pressure composite pipe of the present invention comprises a pipe-shaped inner layer made of a synthetic resin, a reinforcing layer made of a stretched polyolefin resin sheet and wound on an external circumferential surface of the inner layer, and an outer layer made of a synthetic resin and disposed on an external circumferential surface of the reinforcing layer. The winding direction of the reinforcing layer is oriented at a predetermined angle relative to the axis of the pipe. Between the inner layer and the reinforcing layer and between the outer layer and the reinforcing layer, adhesion layers having affinity to these layers are interposed.
