Nonaqueous solvent batteries that use lithium or sodium as negative electrode active materials have high energy density, excellent storage characteristics, and a wide operating temperature range, and are often used as backup power sources for calculators, watches, and memories. Such a battery has a negative electrode,
It consists of an electrolyte and a positive electrode, and generally an alkali metal such as lithium or sodium is used as the negative electrode, and propylene carbonate or γ- as the electrolyte.
A solution prepared by dissolving an electrolyte such as lithium perchlorate or lithium borofluoride in a nonaqueous solvent such as butyrolactone or dimethoxyethane is used, and manganese dioxide, graphite fluoride, or the like is used as the positive electrode, respectively.

している。 Among the batteries mentioned above, lithium is used for the negative electrode,
So-called lithium-thionyl chloride batteries, which use thionyl chloride (SOCl 2 ) as the main positive electrode active material, are attracting attention because of their particularly high energy density. Such batteries have a positive electrode made of a porous carbon body and a metal current collector, and generally use thionyl chloride (SOCl 2 ) in which lithium chloride (LiCl) and aluminum chloride (AlCl 3 ) are dissolved as an electrolyte. Therefore, SOCl 2 serves both as a positive electrode active material and as an electrolyte.

る欠点を招く。 By the way, in the above lithium thionyl chloride battery, since the positive electrode active material SOCl 2 is in direct contact with the negative electrode lithium, a LiCl film as a reaction product is generated on the surface of the negative electrode lithium. This generated LiCl
The film has the function of preventing direct contact between the negative electrode lithium and SOCl 2 , and plays a role in preventing battery capacity deterioration during storage. However, during discharging, it acts as a resistive component and causes a voltage drop in the early stages of discharge. Become.
In addition, this LiCl film peels off due to discharge and the voltage recovers accordingly, so it does not pose a problem in the middle or late stages of discharge, but it has the disadvantage of inducing a large voltage drop in the early stages of discharge, especially during large current discharge. invite

The present inventors provided a negative electrode such as lithium and a positive electrode mainly composed of porous carbon in a can with a separator interposed therebetween, and installed thionyl chloride (SOCl 2 ), which also serves as a positive electrode active material, as the main component in the can. In a non-aqueous battery containing an electrolyte as a component, the electrolyte contains
When SO 2 and HCl were added, even if a LiCl film grew on the negative electrode lithium surface, the
We have discovered a non-aqueous solvent battery that can prevent significant voltage drops by removing the LiCl film. The reason why the LiCl film on the negative electrode lithium surface peels off in this way is that SO 2
This is believed to be because when the gas and HCl gas are added, the form of the LiCl film formed on the negative electrode lithium surface is changed due to the synergistic effect of the two gases. At present, the reason for this is unknown, but the crystal structure of LiCl is changing, and during the initial discharge, the lithium surface of the negative electrode changes.
It is thought that the LiCl film becomes easier to peel off, and as a result, it is possible to prevent voltage drop at the initial stage of discharge.

間、SO2とHClとを電解液に添加できる利点を有
する。 As a means of adding SO 2 and HCl to the electrolytic solution, for example, a method of sealing gases of SO 2 and HCl in a can at a predetermined partial pressure, or a method of adding SO 2 at a predetermined mixing ratio.
Examples include a method of bubbling HCl gas into an electrolytic solution. In particular, the former method has the advantage that SO 2 and HCl can be added to the electrolytic solution for a considerable period of time since the gases of SO 2 and HCl are sealed inside the can.
