系二次電池に関するものである。[Detailed description of the invention] (a) Industrial application field The present invention comprises a positive electrode made of a rechargeable active material such as molybdenum trioxide, vanadium pentoxide, titanium or niobium sulfide, and lithium as the active material. The present invention relates to a non-aqueous secondary battery equipped with a negative electrode.

金属リチウムとして電析する反応であるが、電析リチウ
ムは樹枝状に成長する傾向があり最終的に正極に達して
内部短絡を引起すという問題がある。(b) Conventional technology In this type of secondary battery, lithium, which is the active material of the negative electrode, becomes ions and dissolves during discharging, and during charging, the reaction is reversed to deposit metal lithium on the negative electrode. The problem is that lithium tends to grow in a dendritic fashion, eventually reaching the positive electrode and causing an internal short circuit.

制されるためである。In order to deal with such inconveniences, for example,
It has been proposed to use a lithium alloy as a negative electrode, such as the lithium-aluminum alloy disclosed in Japanese Patent No. 5423. The advantages of lithium alloys are as follows. That is, in the case of lithium alone, when lithium is eluted as ions, the negative electrode surface becomes uneven, and during subsequent charging, lithium is deposited intensively on the protrusions and grows in a dendritic shape. This is because, in the case of a lithium-aluminum alloy, lithium restores itself to form an alloy with aluminum, which is the base of the negative electrode, during charging, thereby suppressing dendritic growth of lithium.

した際外周側の合金が脱落しサイクル特性の劣化が生じ
る。(c) Problems to be solved by the invention By the way, when a spiral electrode body is formed using such a negative electrode plate made of a lithium-aluminum alloy, the inner circumferential side of the negative electrode plate is better than the outer circumferential side. The tensile strength is strong, while the higher the lithium alloying ratio, the weaker the mechanical strength. Therefore, if the lithium alloying ratios on the inner and outer sides of the negative electrode plate are the same, or the outer side is higher, the alloy on the outer side will fall off during winding, resulting in deterioration of cycle characteristics.
（ニ）問題点を解決するための手段
負極板として、リチウムの合金化率が内周側より外周側
の方が小であるリチウム−アルミニウム合金を用いる。(d) Means for solving the problem A lithium-aluminum alloy is used as the negative electrode plate, in which the alloying rate of lithium is smaller on the outer circumferential side than on the inner circumferential side.
（ホ） 作用
リチウム−アルミニウム合金よりなる負極板の外周側は
リチウム合金化率が小であるため、内周側に比して機械
的強度が強い。それ故、この負極板を用いて渦巻電極体
を形成した場合、負極板の外周側の合金の脱落は抑制さ
れサイクル特性が向上する。(e) Function: Since the outer circumferential side of the negative electrode plate made of a lithium-aluminum alloy has a small lithium alloying ratio, its mechanical strength is stronger than that on the inner circumferential side. Therefore, when a spiral electrode body is formed using this negative electrode plate, falling off of the alloy on the outer peripheral side of the negative electrode plate is suppressed, and cycle characteristics are improved.
