Abstract
【解決手段】負極板、セパレータ、電解液、および黒鉛粉体を正極活物質中に含む正極板を備えてなる電槽化成処理した鉛蓄電池において、前記正極板が正極活物質として高温処理を施していない天然黒鉛粉体に硫酸および酸化剤からなる溶液中で硫酸をインターカレート(黒鉛結晶の層間に挿入)して作製した天然黒鉛粉体を含むことを特徴とする電槽化成が施される鉛蓄電池。
【選択図】 なし
Description
原料の天然黒鉛塊を粉砕機により粉砕し、平均粒径0.3mmに分級した天然黒鉛粉体を1Nの希硫酸水溶液中での浮遊選鉱法により、シリカ、アルミナなどの不溶性不純物及び溶解性の金属不純物の除去を行う。不純物を除去した天然黒鉛粉体は、濃硫酸と過酸化水素の80℃の混合溶液に30分間浸漬した。その後天然黒鉛粉体を収集、水洗、および乾燥して、硫酸をインターカレート(黒鉛結晶の層間に挿入)した天然黒鉛粉体を得る。得られた前記天然黒鉛粉体を正極活物質の鉛粉体、およびポリエステル繊維と乾式混合した後、水および硫酸と混練して正極用活物質ペーストを作製する。この正極用活物質ペーストをPb系合金の鋳造格子板に所定量充填した後、熟成処理を施して正極板を作製する。このように作製した正極板を負極板、セパレータ、電槽、電解液などの電池構成部品と組み合わせて制御弁式鉛蓄電池を組み立て、組み立て後に化成する電槽化成処理が施こされる本発明に係る鉛蓄電池を作製する。
中国産の天然黒鉛塊(鱗状塊)を粉砕し、300μmに分級した後選鉱処理により不純物除去を行った。次に、80℃の濃硫酸と過酸化水素との混酸中に0.5〜2.0時間浸漬して天然黒鉛層間化合物粉体を作製し、本発明例の黒鉛粉体No.1〜4とした。
Claims (2)
- 負極板、セパレータ、電解液、および黒鉛粉体を正極活物質中に含む正極板を備え電槽化成が施される鉛蓄電池において、前記黒鉛粉体が高温処理を施していない天然黒鉛粉体を硫酸および酸化剤からなる溶液中に浸漬処理されたものであることを特徴とする鉛蓄電池。
- 前記酸化剤が、過酸化水素、または重クロム酸カリウム、又はこれらと同等以上の酸化力を有する酸化剤であることを特徴とする請求項1記載の鉛蓄電池。
