Title (EN) ALKALINE BATTERY SEPARATORS HAVING CONTROLLED PORE SIZE
(FR) SÉPARATEURS DE BATTERIE ALCALINE AYANT UNE TAILLE DE PORE CONTRÔLÉE
Abstract:
(EN) An alkaline battery separator comprising a blend of polyvinyl alcohol and a cellulose derivative having a controlled pore size including highly fibrillating a cellulose derivative, and, optionally, cellulose and combining with PVA. A method of making an alkaline battery separator comprising a blend of polyvinyl alcohol and a cellulose derivative having a controlled pore size is further included.
(FR) Cette invention concerne un séparateur de batterie alcaline, comprenant un mélange d'alcool polyvinylique et d'un dérivé de cellulose ayant une taille de pore contrôlée formé par fibrillation poussée d'un dérivé de cellulose, et, facultativement, de cellulose et combinaison avec du PVA. L'invention concerne en outre un procédé de fabrication d'un séparateur de batterie alcaline comprenant un mélange d'alcool polyvinylique et d'un dérivé de cellulose ayant une taille de pore contrôlée.
