摘要:
A carbon material for negative electrode of a secondary battery, in particular lithium-ion secondary battery, is prepared by pyrolysis in an inert gas atmosphere or in a vacuum of a composite resin obtained by dissolving pitch in a pitch-soluble resin such as a nobolac phenol resin as it is, or a resin solidified by curing treatment in a state in which the above composite resin is dispersed in a resin solidified by curing treatment or in an uncured resin having a phenol hydroxyl radical such as resol type phenol resin, followed by pulverization in an inert gas, and further heat treatment in an inert gas atmosphere or in a vacuum. Also, a negative electrode material with which irreversible capacity is small, initial discharge capacity is large, and capacity decrease due to cycles is small can be provided by pyrolyzing in an inert gas atmosphere or in a vacuum powder of a resin such as a resol type phenol resin the primary chain of which containing an aromatic compound, or pyrolyzing in an inert gas atmosphere or in a vacuum in a first step, followed by heat treatment in a vacuum in a second step. By employing these negative electrode materials, it is possible to achieve a higher capacity in lithium-ion secondary batteries.

摘要:
A solid electrolytic capacitor comprising an anodized valve metal anode and a cathode provided in face-to-face relation with the anode, between which a layer of a solid electrolyte is provided. The solid electrolyte consists essentially of a tetracyanoquinodimethane complex salt and neutral tetracyanoquinodimethane. In order to suppress generation of toxic gases such as HCN, polyhydric alcohols may be further added to the solid electrolyte.
摘要:
A film of poly(methacrylamide) is heated to partially form imide bonds with elimination of ammonia, and such imide bonding causes crosslinking in the polymer to form a crosslinked polymer film. This film can be advantageously adapted as a positive resist capable of forming a positive image by exposure to radiation such as electron beams. The minimum incident charge required for such exposure is of the order of 10.sup.-7 coulomb/cm.sup.2, which is far lower than the level required in the use of conventional resists. The resist provided according to this invention is also capable of forming an excellent heat-resistant positive resist image by short-time exposure to radiation.
摘要:
An electrochromic display device comprises a pair of first and second, opposed insulative substrates, a layer of electrochromic substance sandwiched between the substrates, a transparent display electrode on the first substrate, and a counter electrode on the second substrate. A dielectric layer analogous in pattern to the display electrode is formed on the counter electrode to improve the device's life time and eliminate interference between adjacent display electrodes.
