| description | To provide a high molecular weight hydrogen ion-form alginic acid which, due to its high binding capacity and high toughness, can be used as a binder for a lithium ion battery electrode, which is free from cracks and peeling/exfoliation.SOLUTION: Provided is a high molecular weight hydrogen ion-form alginic acid, where the weight average molecular weight is 500,000 to 1,500,000 and the hydrogen ion replacement ratio is 80 to 99%. The high molecular weight hydrogen ion-type alginic acid can be produced by dispersing at least one of alginic acid alkali metal salt or alginic acid alkaline earth metal salt in a poor solvent therefor and, further, by adding an acid to subject at least one of the alginic acid alkali metal salt or alginic acid alkaline earth metal salt to ion exchange in a dispersed state into a hydrogen ion form.SELECTED DRAWING: None
【課題】結着性が高く靭性も高いため、クラックや剥離・剥落のないリチウムイオン電池電極用バインダとして使用できる高分子量水素イオン形アルギン酸を提供する。【解決手段】重量平均分子量が５００,０００～１,５００,０００で水素イオン置換率が８０～９９％である高分子量水素イオン形アルギン酸。当該高分子量水素イオン形アルギン酸は、アルギン酸アルカリ金属塩またはアルギン酸アルカリ土類金属塩の少なくともいずれかを、それらの貧溶媒に分散させ、さらに酸を添加して分散状態でアルギン酸アルカリ金属塩またはアルギン酸土類金属塩の少なくともいずれかを水素イオン形にイオン交換することで製造できる。【選択図】 なし |
