摘要:
An absorbent battery separator comprising a substantially homogeneous blend of a thermoplastic polymer and of at least one inert filler, where the inert filler is pyrogenic silica, precipitated silica, titanium dioxide, magnesium carbonate, magnesium oxide and magnesium hydroxide, or mixtures thereof and, the separator has a volume porosity of at least 75% and an extraction pore size of greater than 2 microns.
摘要:
The present invention concerns non-woven, cartridge belt type gauntlet for lead acid batteries comprising two sheets of spunbond, needled and flat calendared thermobonded bicomponent PET-PBT nonwoven fabric assembled together at regular intervals.
摘要:
The invention provides a gauntlet for tubular type electric storage batteries with air mixing of the electrolyte, the gauntlet including multiple individual tubes forming a cartridge belt type gauntlet, where the walls of at least one of these individual tubes are substantially impermeable to air, as well as a process for its manufacture. The invention further pertains to an electric storage battery using such gauntlets.
摘要:
The invention is related to a protection for a positive flat electrode of a lead acid battery, said protection comprising two flat faces made of a shrinkable material, said flat faces having two lateral sides, a lower side and an upper side, said flat faces being joined together along said lateral sides according to a first kind of assembly, said protection being open between said upper sides, said protection being further open between said lower sides or being closed along said lower sides by a join assembling said flat faces according to another kind of assembly.
摘要:
A process for manufacturing of a plate electrode stacking for use in batteries, comprising the steps of supplying a separator material comprising a polymer sheet layer, optionally reinforced with a polyester mat, with an overlapping portion and a glass mat layer, placing a positive plate electrode onto the glass mat layer, folding and wrapping this separator material around the positive plate electrode, attaching an overlapping portion to form a sleeved plate electrode, and placing a negative plate electrode onto the sleeved positive plate electrode.
