摘要:
An alkaline cell with improved separator. The separator is formed of two sheets (130a, 130b). The two sheets are wound into, a tube shape and the bottom edge of the wound separator is folded and heat sealed. The facing surfaces of the two sheets forming the separator body are not glued or bonded together. The two separator sheets may overlap laterally so that a portion of each sheet forms a different portion of the separator outside surface. Alternatively, the separator may be formed of two sheets wherein the first sheet forms an outer layer which completely covers the second sheet. One sheet is preferably composed of a blend of polyvinylalcohol fibers and rayon fibers and the other sheet composed of polyvinylalcohol fibers and wood pulp fibers.
摘要:
Batteries are provided that include a tubular battery separator having a locally strengthened region. The strengthened region maybe provided by including a folded area adjacent an open end of the tubular separator.
摘要:
Electrochemical double layer capacitors are disclosed that advantageously include separators comprising at least one porous layer of nanofibers having average diameters of between about 50 nm and about 1000 nm that provide improved combinations of reduced thickness, barrier against the development of soft short-circuits and low ionic resistance as compared with known capacitor separators.
摘要:
The present invention relates to an electrochemical cell comprising an anode, a cathode, and a separator disposed between the anode and cathode. More particularly, the present invention relates to an electrochemical cell comprising, among other things, a separator impregnated with, and/or coated with a layer of, a clay and/or a metal sulfide additive. The present invention additionally or alternatively relates to an electrochemical cell which comprises, among other things, a self-supporting or free-standing thin film separator. The present invention additionally or alternatively relates to an electrochemical cell which comprises, among other things, a separator, wherein at least a portion thereof is covered by an adhesive material that is bonded to the container or a sealing assembly of the cell.
摘要:
The present invention relates to batteries that can be activated by liquid. The battery with porous material is suitable for disposable healthcare test kits, bioMEMS (bio Micro Electro Mechanical Systems) and biosystems such as DNA chips, lab-on-a-chip or micro fluidics and can be easily integrated with disposable devices/systems.
