A management system displays a list of elements of some element types from among a plurality of element types, and receives a selection of the two or more elements from the list. The management system displays a topology which is configured of the two or more selected elements and an element (related element) related to the two or more selected elements and in which the two or more selected elements and the related element are segmented by element types.

Management system that manages computer system

A management system (A) assigns a priority to each of a plurality of elements matching a predetermined condition based on management information including information representing a relation among elements and information representing a metric of each of the elements, (B) displays a visual representing a visual priority given to each of element based on one or more priorities given in (A), (C) when receiving selection of the elements from the visual displayed in (B), selects a higher or lower level layer of a layer containing a selected element, and selects one or more elements related to the selected element and contained in the selected layer, based on a level relation among a plurality of layers and a correlation between element types and layers, and (D) performs (A) with the one or more elements selected in (C) treated as the one or more elements matching the predetermined condition.

Management system for computer system

A management system displays a plurality of elements detected from an information system according to a horizontal relation view (HRV) format which is a multi-column display format, based on information of the plurality of detected elements. In the HRV format display, the plurality of columns correspond to a plurality of types, and include a key column which is a column serving as a key for aggregated display and an aggregation target column subjected to aggregated display according to the key column. The key column includes key objects which represent information on elements belonging to the corresponding type and which are arranged vertically. A lateral area of each of the key objects in the aggregation target column includes aggregation objects indicating aggregation information of elements related to an element represented by the key object, whereby the key objects and the related aggregation objects are arranged on the same row.

When an electrode material having a weight-average mesopore/macropore specific surface area within a specific range is used, there arises an expansion of a cell caused by the generation of decomposed gas from a component of electrolyte solution during the pre-doping process of lithium ions. A potential drop upon the pre-doping process is adjusted so as to reduce or suppress the expansion of the cell. Specifically, since the pre-doping speed is increased, the negative electrode can speedily reach the potential by which an SEI component made of lithium alkyl carbonate can be produced on the surface of the negative electrode. Consequently, the absolute amount of the gas produced by the decomposition of the electrolyte solution can be reduced, whereby the expansion of the electric storage device can be reduced.

Electric storage device and its production method

[Problem] The present invention aims to enhance a characteristic of a lithium ion electric storage device upon charging or discharging with high load, and increasing a working temperature range thereof. [Means for Solving Problem] In a positive electrode active material used for a lithium ion electric storage device, the BET specific surface area is 1500 m/g or more and 3000 m/g or less, the ratio A of the pore volume within the range of the pore diameter of 0.6 nm or more and less than 1 nm to the pore volume within the range of the pore diameter of 0.6 nm or more and 200 nm or less in the active material satisfies 0&#x2266;A&#x2266;0.80, and the ratio B of the active material of the pore volume within the range of the pore diameter of 1 nm or more and 6 nm or less to the pore volume within the range of the pore diameter of 0.6 nm or more and 200 nm or less in the active material satisfies 0.20&#x2266;B&#x2266;1.0. By virtue of this structure, the lithium ion electric storage device can be provided that is excellent in the charging/discharging characteristic when it is given a high load, and that can satisfactorily operate even under an environment of &#x2212;30&#xb0; C.

An organic electrolyte capacitor. The organic capacitor is made up of a positive electrode, a negative electrode, and an electrolyte capable of transporting lithium ions. The organic capacitor exhibits a small change in internal resistance during charge and discharge, a high energy and a high output power, and allows lithium ions to move with ease. This is achieved by having a positive electrode that is able to support lithium ions and anions reversibly, a negative electrode that is able to support lithium ions reversibly, and controlling the ratio of positive electrode active material to negative electrode active material within an optimized range.
