(TW219377-A)      Electrochemical energy storage apparatus use hydrophilic separation material made of non-woven cloth, the electrochemical energy storage apparatus contains aqueous alkaline electrolyte, in which the non-woven cloth is constituted of polyamide and/or polyalkene fibers of different softening temperature range, by heating and pressing to soften, solidify, and press the fiber with lower melting point; which is characterized in that the separation material is rinsed by de-ionized water before use, the quantity is 0.5~7% weight of the dry weight.    (JP6215750-A)      Non-woven hydrophilised separator fleece material (I) for use in electro-chemical accummulators with aq. alkaline electrolyte consists of a mixt. (II) of polyamide and/or polyolefin fibres with different softening points and is consolidated by heating and pressing to weld the fibre fraction (IIA) with the lower softening point. The novelty is that, before use, (I) is moistened with 0.5-7 (wt)% deionised water (III). $    (I) is made by laying up (II) contg. 30-50% (IIA) on a card, heating in an oven to soften (IIA) only, followed by calibration by pressing to the required final thickness and cooling, spraying at room temp. with 0.5-1% (III) and winding it up for 1 hr. $    ADVANTAGE -   The technique dispenses with the need to add surfactants before or after prodn. of (I) and ensures that it can be wetted with 30% aq. alkali soln. and is compatible with all materials of the accumulator.    (US5401594-A)      A hydrophilised separator material comprises a non woven fabric formed from a mixture of fibres having different softening ranges with 30 to 50 per cent of the fibres of material with a lower softening point than the remaining fibres and selected from polyamide, polyolefin fibres wherein the fibres are compressed and bonded together to form a layer of separator material moistened with deionised water to 0.5 to 7 per cent of dry weight.    USE/ADVANTAGE -   As flat flexible electrolyte resistant separator. Wets rapidly with aqueous alkaline electrolyte.
