Abstract

En la presente se proporciona un método para preparar montajes de electrodos para baterías de iones de litio. El método descrito en la presente comprende un paso de secado previo del separador en el proceso de fabricación de baterías antes de la etapa de apilamiento, disminuyendo, por lo tanto, significativamente el contenido de agua del separador. Por consiguiente, los separadores se pueden usar para preparar montajes de electrodos independientemente de las condiciones bajo las cuales se almacenan o transportan. Además, la fuerza de adherencia entre el material de base porosa y la capa porosa protectora no se ve afectada en gran medida por el proceso de secado descrito en la presente.
