Abstract
Настоящее изобретение относится к микропористому полимерному сепаратору для аккумулятора, состоящему из одного слоя переплетённых микроволокон и нановолокон. Такой сепаратор дает возможность регулировать пористость и размер пор нетканого материала до любого искомого значения. В результате сепаратор по изобретению обеспечивает высокую прочность материала с низкой пористостью и низким размером пор до недостижимого ранее уровня. Комбинирование полимерных нановолокон в полимерной матрице микроволокон и/или на такой подложке путем обработки с высоким усилием сдвига также обеспечивает указанные преимущества. В объём притязаний по настоящему изобретению входят сепаратор, аккумулятор, включающий такой сепаратор, способ изготовления такого сепаратора и способ использования такого сепаратора в устройстве аккумулятора.
