摘要： To overcome the drawbacks of a P(VDF-HFP) system gel electrolyte and a cell using the same, a polymer having a vinylidene fluoride copolymer as a backbone and poly-vinylidene fluoride in a side chain featuring good adhesion and exhibiting electro-chemical properties similar to the P(VDF-HFP) system without a crosslinking step is used as a binder for a gel electrolyte or electrode. The invention improves the adhesion of gel electrolyte to a current collector or electrode to reduce internal resistance; develops a polymeric solid electrolyte which is storage stable and capable of continuous lamination of coating layers; and provides an electrode which does not require an extra crosslinking step in assembly procedure, prevents positive and negative electrode materials from stripping off, and experiences a minimal capacitance drop upon repetitive charge/discharge cycles. A lithium secondary cell and an electric double-layer capacitor using the electrode is also described.

The anode includes a plurality of circumferentially arranged electrode segments formed of a valve metal material and coated with a platinum group metal or oxide thereof. The electrode segments are removably attached and electrically connected to a back plate. The split anode is easy in assembly and disassembly and, hence, in maintenance and repair, has a high degree of precision in configuration and dimensions, and ensures manufacture of copper foil of quality with a minimized variation in thickness during continuous operation.

摘要： The cigarette lighter of the invention has an igniter member which promotes smooth burning of the fuel gas ejected from the gas nozzle. The igniter member is composed of an igniting element which is a coiled wire of platinum metal or a platinum-based alloy having a specified dimensions and a supporting member made of a wire of a refractory metal or alloy. The coil of platinum wire preferably has a flattened configuration to cover a larger front of the flame. The supporting member made of a wire of a refractory metal or alloy, around which the coil is wound, is preferably coated with a coating layer of a ceramic material, e.g., alumina. A simple but very reliable structure for mounting the igniter member in the fire bowl of the cigarette lighter is described.
