ものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a non-aqueous electrolyte battery, and more specifically, uses an alkali metal or alkaline earth metal such as lithium or sodium as a negative electrode active material and a positive electrode active material as a positive electrode active material. The present invention relates to a non-aqueous electrolyte battery using molybdenum trioxide.

き結着剤を混合した後、加圧成形している。<Prior art> In such a non-aqueous electrolyte battery, conventionally, the preparation of a positive electrode using molybdenum trioxide MOO3 as an active material involves mixing molybdenum trioxide with a conductive agent such as graphite and tetrafluoroethylene resin (PTFE). After mixing a binder such as a powder or a dispersion thereof, the mixture is press-molded.
〈発明が解決しようとする問題点〉
しかしながら、上記従来電池では、正極中に含有された

過電圧が上昇するという問題がある。<Problems to be Solved by the Invention> However, in the above-mentioned conventional battery, the surface of molybdenum trioxide particles, which are active materials, or the surface of conductive agent particles is As a result of being coated, the movement of ions and electron conduction within the positive electrode are inhibited, and there is a problem in that the overvoltage during discharging (when charging and discharging in the case of secondary batteries) increases accordingly.
また、この種の結着剤は１發水性が強いことから、電解

問題もある。Furthermore, since this type of binder is highly hydrophilic, leakage during injection of electrolyte becomes worse and the liquid absorption rate of the positive electrode becomes slower. For this reason, it is difficult to sufficiently impregnate the electrolyte into the pores within the positive electrode, and the electrolyte in the separator may migrate to the positive electrode during storage or discharge (during charge/discharge cycles in the case of secondary batteries). Since the amount of liquid in the separator decreases, there is also the problem that the internal resistance of the battery increases, resulting in a decrease in battery performance.

ンの１０失が大きくなるためである。For such a positive electrode, for example, a mixture of molybdenum trioxide powder mixed with powders such as graphite, acetylene black, nickel, and titanium as a conductive agent is press-molded in a non-oxidizing atmosphere (such as an argon atmosphere). For example, the mixture may be solidified by sintering to bind the particles in the mixture to each other. The heating temperature during sintering varies depending on the particle size of the molybdenum trioxide powder and conductive agent powder in the mixture, molding pressure, heating time, etc., but is preferably in the range of approximately 700 to 800°C. . At temperatures below 700'C, sintering will be insufficient and the mechanical strength of the positive electrode will be insufficient; at temperatures above 800'C, molybdenum trioxide (melting point approximately 795°C) will melt or sublimate, making the positive electrode This is because as the porosity decreases, the loss of molybdenum trioxide due to sublimation increases.
