ントフィトが原因と考えられる充放電効率の低下により
、電池容量が減少し、問題であった。A large number of configurations are possible depending on the combination of these positive and negative electrodes and electrolytes, but when considering the energy density of the battery, a system using metallic lithium as the negative electrode is considered to be the most advantageous. A battery using a solution of propylene carbonate in which lithium perchlorate is dissolved as an electrolyte and a negative electrode of decreased, which was a problem.
また、最近では、種４の添加剤が提案されているが、依

的とする。OBJECTS OF THE INVENTION In view of the above problems, an object of the present invention is to provide a lithium secondary battery with improved charge/discharge efficiency and cycle life.

作用
リチウムの充放電効率が低くなる原因として・リチウム
による溶媒の還元反応により、リチウムが電気化学的に
不活性化すること、及び析出したリチウムの脱落（リチ
ウム表面と非接触。）によるものと考えられる。The reason for the low charging and discharging efficiency of lithium is thought to be that lithium becomes electrochemically inactive due to the reduction reaction of the solvent by lithium, and that the precipitated lithium falls off (not in contact with the lithium surface). It will be done.
したがって、電解液中におけるリチウムの充放電効率を
向上させるためには、リチウム極と電解液−の界面の状
態を変化させ、溶媒−リチウム間の反応、及びデンドラ
イトの成長を抑制する必要がある。上記の構成に釦いて
、リチウムの充放電効率は向上する。Therefore, in order to improve the charging and discharging efficiency of lithium in the electrolyte, it is necessary to change the state of the interface between the lithium electrode and the electrolyte to suppress the reaction between the solvent and lithium and the growth of dendrites. With the above configuration, the charging and discharging efficiency of lithium is improved.
その理由は明確ではないが、
■ 添加剤がリチウム極に吸着され、溶媒とリチウムの
反応を抑制する。The reason for this is not clear; (1) The additive is adsorbed to the lithium electrode and suppresses the reaction between the solvent and lithium.
■ 添加剤がリチウムと反応し、リチウム極表面にＬｉ
イオン伝導性の保護膜を形成する。■ The additive reacts with lithium, and Li is deposited on the lithium electrode surface.
Forms an ion-conductive protective film.
リチウムイオンは、その膜を通って析出するため、溶媒
との直接反応が抑制される〇の２点と推察される。Since lithium ions precipitate through the membrane, it is assumed that the direct reaction with the solvent is suppressed.

/l is appropriate. The reason is that 0.01mo
If it is less than l/1, the effect of addition is small,
This is because if the amount is more than 1.0 mol/l, the excessive amount of the additive will have an adverse effect on the ionic conductivity and the electrochemical reaction of the lithium electrode, and the properties will deteriorate compared to the amount added.
