Embodiment 1 and 2

[0093] (Manufacture of aramid tissue paper material)

[0094] The prepared aramid fibrids, aramid short fibers and fibrillated aramid were dispersed in water respectively to make a slurry. These slurries were mixed so that aramid fibrids, aramid staple fibers and fibrillated aramid were the mixing ratios of the examples shown in Table 1, and passed through a tapi-type hand paper machine (cut Area 325cm 2 ) into flakes. Next, this was subjected to hot press processing with a metal calender roll at a temperature of 330° C. and a linear pressure of 100 kg / cm to obtain a thin paper material.

[0095] Table 1 shows the main characteristic values ​​of the aramid tissue material obtained above.

Abstract

An aramid tissue material composed of two components, aramid short fibers and fibrillated aramid, or these two components and aramid hybrid, characterized in that the following expressions (1) and (2) / are satisfied; [Internal resistance] (mum))>=0.5 (sec / 100 cm) expression (2), wherein the [internal resistance] is a resistance being calculated according to the following expression (3); [Internal resistance] (mum)=[electric conductivity of electrolyte] / [electric conductivity when electrolyte is injected into tissue material]x[thickness of tissue material] (mum) formula (3).

Description

technical field [0001] The present invention relates to an aramid thin paper material useful as a separator for isolating conductive materials in electrical and electronic components and allowing electrolytes or ionic plasma species to pass through, and electrical and electronic components using the material. In particular, it relates to an aramid thin paper material that can be used as a separator between electrodes of capacitors, capacitors, batteries, etc. that use lithium ions, sodium ions, ammonium ions, hydrogen ions, etc. as current carriers . Background technique [0002] As a symbol of recent advances in portable communication devices and high-speed information processing machines, the miniaturization, weight reduction, and high performance of electronic devices are attracting attention. Among them, people have great expectations for high-performance batteries and capacitors (condensers) that are small, lightweight, high-capacity, and can be stored for a long time,...
