ｌノで用いてきた。Conventionally, in high-temperature type batteries that use molten salt, separator materials have been used in terms of stability at 500°C, which is the operating temperature of the battery, corrosion resistance in molten salt, reaction fl with active materials, etc. Since then, boron nitride has been used to make a porous material by making felt.

形電池の大きな問題どなっていた。Although boron nitride felt separators fully satisfy the characteristics required for battery separators, such as retention of active materials and electrical insulator η, the cost of making felt to make IZ parators porous is very high. This has become a major problem with high-temperature batteries.

A lithium-iron sulfide battery according to the present invention as shown in FIG. 1 was assembled and tested by filling the space between the electrodes with 150 μm of lithium iron sulfide. In the figure, (1) is a positive electrode in which iron sulfide is covered with an active material, and after filling a honeycomb-shaped current collector with iron sulfide powder, it is formed into a plate shape by pressure molding at room temperature.

(2) is a separator filled with porous boron nitride particles according to the present invention, and (3) is a negative electrode using a porium aluminum alloy as an active material. Similar to the positive electrode, the negative electrode is also filled with active material powder in a honeycomb-shaped current collector, and is heated to room temperature with U m J, T
It is a molded plate-like body. (-11i also has a 200 mesh rope on the surface to hold the active material.)
A molten salt of lithium chloride-potassium chloride was used as the electrolyte, and the operation was performed at 470°C.

．． It was tripled. The porosity of the leverator using porous boron nitride particles according to the present invention is 78%, which is inferior to 89% of boron nitride felt, but it is sufficiently porous and even in battery tests at 2.5Δ charge/discharge. The positive electrode active material utilization rate was as high as 83%. This value was equivalent to the active material utilization rate in a similar battery using boron nitride (boron nitride) as the separator.

充分に達成けしめるものである。As is clear from the description and examples of J.S.
The problem was solved by filling the space between the electrodes with inexpensive porous particles and covering them with the separator, without using a tidy method.
However, the same value as that of a battery using a nitrided felt separator can be sufficiently achieved by using a separator using inexpensive particles as the raw material r1.

工程で行えるという利点も併せて有する。The battery according to the present invention also has the advantage that it can be assembled by a simple process of inserting the positive and negative electrode plates into the battery case and then pouring porous particles between the electrodes.
