Description
上記セパレータ3として、平均繊維径が0.8μmのガラス繊維のみからなるもの(A)、平均繊維径が0.8μmのガラス繊維に平均繊維径が15μmのアクリル繊維9質量%、ポリエステル繊維6質量%、オレフィン繊維12質量%を混抄させたもの(B)、平均繊維径が0.8μmのガラス繊維に平均繊維径が15μmのアクリル繊維9質量%、ポリエステル繊維6質量%、オレフィン繊維12質量%を混抄させたマットに平均粒子径が15nmのシリカ粉末を分散させたもの(C)、の3種類を準備し、各セパレータ(A)〜(C)を用いた制御弁式鉛蓄電池には、比重が1.220の希硫酸を電解液として注液して電槽化成するとともに、別の(B)を用いた制御弁式鉛蓄電池には、電槽化成後の質量比が、電槽化成後の電解液質量に対して質量%(以下同じ)が0.3%、0.5%、1.0%、1.5%、2.0%、3.0%、5.0%、7.0%になるように調製したシリカを希硫酸に添加し、比重が1.220の希硫酸の硫酸根量と同じになるように調製し、混合、攪拌することによってシリカゾルにしたものを電解液として注液して電槽化成し、それぞれを5個単位で作製した。作製した電池は電圧が2V、初期容量が25AH(5時間率)である。なお、シリカは日産化学工業製のスノーテックス20(商品名)を使用した。なお、作製した制御弁式鉛蓄電池は、セパレータ3が(A)のものをa、セパレータ3が(B)のものをb、セパレータ3が(C)のものをcとし、セパレータ3が(B)のもので、シリカを添加していないものをb0、シリカを0.3%添加したものをb1、シリカを0.5%添加したものをb2、シリカを1.0%添加したものをb3、シリカを1.5%添加したものをb4、シリカを2.0%添加したものをb5、シリカを3.0%添加したものをb6、シリカを5.0%添加したものをb7、シリカを7.0%添加したものをb8とした(以下、単に電池a、電池b0、・・・のように言う)。
最初のロットで作製した上記した各制御弁式鉛蓄電池を、温度が40℃の恒温槽に入れ、以下に示した「放電1→放電2→充電」を1サイクルとする、充電不足が生じやすい条件下で充放電サイクル試験に供し、放電2における放電電圧が1Vに低下した時点を寿命として、そのサイクル数を表1に示す。なお、表1に示したサイクル数は、5個ずつ試験に供した各電池のうちで、最大のもので示した。
放電1:25Aの定電流放電を60秒間
放電2:250Aの定電流放電を1秒間
充電:25Aの定電流充電を80秒間
次のロットで作製した上記した各制御弁式鉛蓄電池を、温度が40℃の恒温槽に入れ、以下に示した「放電→放置→充電」を1サイクルとする条件下で深放電サイクル試験に供した。そして、放電容量が初期容量の70%に達した時点を寿命として、そのサイクル数を表2に示す。なお、表2に示したサイクル数は、5個ずつ試験に供した各電池のうちで、最大のもので示した。なお、電池bについては、浸透短絡が発生するかどうかの臨界点とシリカの添加量の上限を明らかにするために電池b2、b3、b5、b7、b8を対象とした。
放電:5Aの定電流で放電電圧が1.75Vになるまで放電
放置:定電流放電終了後24時間
充電:2.5Aの定電流で放電容量の130%まで充電
さらに、次の2ロットの10個を、上記した深放電サイクル試験の場合と同様に作製する際に、5枚の正極板2のうち、中央に位置する正極板2の正極格子体の側部ワイヤー(図2(a)にAで示した部位)を、図2(b)で示したように折り曲げておき、前述の充放電サイクル試験に供し、結果を表3に示す。なお、表3に示したサイクル数は、10個ずつ試験に供した各電池のうちで、最大のもので示した。この側部ワイヤーの折曲げは、図2(c)で示したように、正極格子体の両側端が10mm突出するように平板(1)上に載せ、その上に、両端に折り曲げられる平板(3)を有した平板(2)を載せて、平板(3)を平板(1)側に3mm折り曲げることによって行った。
