Abstract
【解決手段】本発明の黒鉛粒子の製造方法は、易黒鉛化性炭素を含有する原料炭素組成物を賦活処理して活性炭を製造する賦活処理工程と、この活性炭を不活性ガス雰囲気下、2000〜3000℃の温度で熱処理して黒鉛の結晶を成長させる熱処理工程と、を備える。この製造方法によれば、炭素原子が平面状に配列して形成される黒鉛結晶シート1aが複数積層してなる積層構造体1を備え、積層構造体1の端部2がループ状に閉じた構造を有し、比表面積が1m2/gより大きく10m2/g以下であることを特徴とする黒鉛粒子が製造される。

Description
ディレードコーカーで製造した石油生コークスを550℃で1時間焼成し、炭化物(原料炭素組成物)を得た。本実施例で使用した石油生コークスの焼成前及び焼成後の物性を表1に示す。
実施例1と同様にして製造した活性炭の熱処理温度を2600℃としたことの他は、実施例1と同様にして黒鉛粒子を製造すると共に、3極セルを作製して充放電テストを行った。表2に黒鉛粒子の物性及び充放電テスト結果を示す。なお、本実施例で製造した黒鉛粒子を透過型電子顕微鏡で観察したところ、黒鉛結晶シートが複数積層してなる積層構造体の端部は、ループ状に閉じた構造となっていた。
実施例1と同様にして製造した活性炭の熱処理温度を1300℃としたことの他は、実施例1と同様にして黒鉛粒子を製造し、更に3極セルを作製して充放電テストを行った。表2に黒鉛粒子の物性及び充放電テスト結果を示す。なお、本比較例で製造した黒鉛粒子を透過型電子顕微鏡で観察したところ、黒鉛結晶シートが複数積層してなる積層構造体の端部はループ状に閉じてはいるが、シートの積層枚数が少なく結晶発達が不十分であった。
実施例1で使用したものと同様の石油生コークスを550℃で1時間焼成して得た炭化物(石油コークス)を、2600℃で30分間焼成することによって、黒鉛粒子を製造した。得られた黒鉛粒子を用いて、実施例1と同様に3極セルを作製して充放電テストを行った。表2に黒鉛粒子の物性及び充放電テスト結果を示す。なお、本比較例で製造した黒鉛粒子を透過型電子顕微鏡で観察したところ、黒鉛結晶シートが複数積層してなる積層構造体の端部はループ状に閉じた構造が形成されず、エッジ面が残存していた。
