摘要： Provided is a solid electrolyte secondary battery with a greater capacity than previous solid electrolyte secondary batteries. Furthermore, the disclosed solid electrolyte secondary battery can obtain a high power output and improve battery function while ensuring a large capacity. The solid electrolyte secondary battery is provided with a cathode chamber, a cathode active material container that is provided independently and stores some cathode active material, and a channel medium that is provided between the two and through which the active material passes. The cathode active material is transferred by the channel medium and heterogeneity, when the active material is discharged, can be curbed. By providing a transfer medium, which transfers the cathode active material, the cathode active material can be forcibly transferred.

摘要： For a cylindrical sodium sulfur cell, a cathode electrode structure is provided with improved electronic conductivity in the radial direction, compared with other directions, by forming a block of fibre material, e.g. graphite fibres, with the fibres aligned in one direction, slicing the block to form a sheet with fibres normal to the plane of the sheet, moulding the sheet and impregnating it with cathodic reactant in a heated mould having a plurality of ribs, to form a plurality of trapezoidal segments with the fibres normal to the planes of the parallel surfaces of the trapezoids, cooling the mould so that the impregnant is solidified and then forming the trapezoids into an annular structure. Preferably the mould is such that thin webs are left joining adjacent trapezoidal sections along parallel edges of the wider of the two parallel faces so that the webs form hinges for folding the segments into the annular assembly.

摘要： In a sodium sulphur cell, a cathode electrode of annular form comprising a plurality of segments, each of trapezoidal form in cross-section is made by compressing a blanket or sheet of carbon or graphite felt or fibres in a heated mould, which is shaped to produce the segments joined by thin webs, the material being impregnated with sulphur or sodium polysulphide before or after insertion in the mould, and the material being cooled before removal from the mould. Alternatively, the segments may be formed from the blanket or sheet by using shaped rolls, the mateial being cooled, e.g., by water or air, as it leaves the rolls.
