電特性は、急激に低下した。Problems to be Solved by the Invention Conventional PC has a high dielectric constant but a high viscosity, so when used in batteries, a drop in voltage and a drop in the utilization rate of the positive electrode occur during high rate discharge. On the other hand, DME and 2-Me-THF
Ethers such as ethers have a low viscosity but a low dielectric constant, so they cannot ionically dissociate solutes such as L I CI 04 at a sufficient rate, resulting in a decrease in battery voltage and utilization rate during high rate discharge. Happened. For this reason, PC and EC
By mixing carbonates such as ethers with ethers, sufficient ionic dissociation of solutes is obtained and the viscosity is lowered, thereby improving the discharge characteristics of batteries. However, when a battery is over-discharged in these electrolytes, the potential of the positive electrode decreases, causing decomposition of carbonate solvents such as PC+EC on the surface of the active material and the surface of the carbon powder used as the conductive agent. , the decomposition products covered the surface of the positive electrode particles, and the subsequent charge-discharge characteristics deteriorated rapidly.

る。In view of the problems of the prior art described above, the present invention, in place of PC and EC, has the ability to sufficiently ionically dissociate the solute Li (JO4, etc.), and does not separate even if the potential of the positive electrode decreases due to overdischarge. The purpose of the present invention is to provide a battery that uses a solvent.
問題点を解決するだめの手段
本発明は、従来の有機電解質に用いる溶媒に、無水コハ

解質電池である。Means for Solving the Problems The present invention is an organic electrolyte battery characterized in that a mixed solvent containing succinic anhydride is used as a solvent for a conventional organic electrolyte.

で、エーテル類との混合溶媒を形成することができる。Effect Succinic anhydride, like EC, is a solid at 20°C. However, since it dissolves in DME and 2-Me-THF, a mixed solvent with ethers can be formed.

：１０が良い。Example 2 Since succinic anhydride is solid at room temperature, mixing with other solvents is necessary. A battery having the same configuration as in Example 1 was made, and a mixed solvent of succinic anhydride and DME was used as the mixed solvent, and the charging/discharging characteristics were examined by changing the mixing ratio. As the solute, lithium hexafluorophosphine (L 1PFe ) having a concentration of 1 mol/4 was used. The charging and discharging conditions were the same as in Example 1. Figure 4 shows the 15th graph when overdischarge was performed while changing the molar ratio of succinic anhydride in the mixed solvent.
The discharge capacity at the cycle was plotted. If succinic anhydride is less than 1 mol per 10 mol of DME, LiP
A decrease in discharge capacity, which seems to be due to insufficient ion dissociation of F cs, was observed, and when the amount exceeds 30 mol, the viscosity increases and all of the succinic anhydride becomes insoluble in DME. Therefore, the ratio of succinic anhydride to DME is 1:10 to 30.
:10 is good.
（実施例３）

。(Example 3) The effect of adding succinic anhydride in the presence of PC and EC, which decompose when overdischarged, was investigated. Using the same battery as in Example 1, succinic anhydride:PC was used as the mixed solvent of the organic electrolyte.
A battery using an electrolyte with :DME of 5:5:10 is designated as F, and a conventional battery using an electrolyte with PC:DME of 5=10 is designated as G. Charging and discharging were performed under the same conditions as in Example 1.

向上していることがわかる。FIG. 6 shows a discharge curve on the 16th cycle day when overdischarge was performed. This shows that the overdischarge characteristics are improved even when succinic anhydride is further added to the conventional mixed solvent of PC and DME.
