摘要： A lithium secondary battery suitable for use as a power source for a secondary battery using system such as an electric automobile, motor bicycle or portable equipment includes a negative electrode (17) composed of a carbon material including carbon particles carrying fine particles of a metal which forms an alloy with lithium. The carbon particles have a face-to-face dimension which is 3.354 to 3.369 ANGSTROM and a crystal grain size in a C-axis direction which is equal to or greater than 300 ANGSTROM . The metal forming an alloy with lithium has a particle size which is equal to or smaller than 1000 ANGSTROM . With the use of the charge/discharge capacity of an alloy of the metal and lithium, a value exceeding the theoretical capacity 372 mAh/g of graphite can be obtained. The lithium secondary battery is capable of discharge with an output energy density equal to or higher than 350 W/kg.

摘要： A sample containing a plurality of components to be analyzed is introduced to a separation column at its top through a sample feeding device. The sample thus introduced is separated to the individual components in the separation column. Ion exchange resins capable of undergoing deformation depending upon an applied pressure are filled in the separation column. An eluting solution containing sodium ions is fed to the separation column at its top under a pressure of 40 kg/cm2 or higher through a feed pump. Components leaving the separation column at its bottom are detected by a detector. After the components have left the separation column, a regenerating solution containing lithium ions is introduced to the separation column at its bottom, and is made to leave the separation column at its top. The ion exchange resins are regenerated by passing the regenerating solution through the separation column, and a separation for another sample is made ready thereby. Another sample is then introduced into the separation column at its bottom and the separated components of the sample are made to leave the separation column at its top.

摘要： The cleaning agent for reforming the inorg. adsorbent comprises a liq. including pressurized gas, a gas retained at above the critical temp. or a liq. including gas at below the critical temp. The adsorbed substances are of various kinds, but have a slight polarity. When a fluid having a polarity such as CO2, NH3, freon etc. used as coolant which is gas at normal temp. under normal pressure, is employed, the reformed liq. becomes gaseous by liberating heat and pressure, and is sepd. easily from the adsorbed substances.

摘要： PROBLEM TO BE SOLVED: To provide a lead-acid battery with excellent high-rate charging capability by enhancing conductivity of lead sulfate and by improving solubility of lead sulfate to lead to smoothly progress the charge reaction of a negative electrode active material, and to provide a carbon material excellent in charge accepting performance for realizing it. SOLUTION: This lead-acid battery has a negative electrode, a positive electrode and an electrolyte. In the lead-acid battery, the negative electrode contains nickel-supporting carbon prepared by supporting nickel and/or a nickel-containing compound to carbon; and the particle diameter of each primary particle of nickel and/or the nickel-containing compound is smaller than that of the primary particle of carbon.
