Abstract: Ionic gel polymer electrolytes for rechargeable polymer batteries preferably are formed by dissolving a gelling agent into organic liquid electrolytes, and then gelling the precursor in situ at elevated temperature after pouring it into a battery case that contains a cathode, an anode and a separator. The gel polymer electrolytes exhibit excellent ionic conductivity of up to about 10?2 S/cm and voltage stability for lithium rechargeable batteries. Most preferably, the gel polymer electrolyte is the reaction product of (A) a heterocyclic amine-group containing material (preferably a vinvlpyridine), and (B) halide or epoxy-group containing polymers, copolymers, oligomers or monomers that are capable of reacting with nitrogen-containing compounds, such as polymers, copolymers, oligomers or monomers containing alkylene halides or halomethyl group substituted aromatic units or at least one epoxy unit.

Abstract: An electrode active material forming composition, a separator forming composition and a manufacturing method of a lithium secondary battery using the compositions are provided.

Abstract: Lithium-ion electrochemical cells include an anode, a cathode and a separator between the anode and cathode, wherein at least one of the anode, cathode and separator includes a polysiloxane coating thereon. Most preferably, the polysiloxane coating is the polymerized reaction product of dimethyl siloxane and tetra(trimethylsiloxy) silane), and is present on the surface in an amount between about 0.05 to about 0.17 mg/cm2. After being coated with the polysiloxane adhesive, the electrodes and separator can easily be attached one to another at ambient temperature by application of pressure using a hand roller or with a laminator, and then subsequently formed into a spiral or stacked structure for placement in a battery cell case.

Abstract: A composition for forming polymer electrolyte and a lithium secondary battery employing the polymer electrolyte prepared using the composition are provided. The composition for forming polymer solid electrolyte having a polymer resin, a plasticizer, a filler and a solvent, wherein the filler is synthetic zeolite having an affinity for an organic solvent or moisture. Therefore, the mechanical strength and ionic conductivity can be improved by adding synthetic zeolite as a filler when forming polymer electrolyte. Also, use of such polymer electrolyte makes it possible to prepare lithium secondary batteries having good high-current discharge characteristics and excellent discharge capacity characteristics even under repeated charge/discharge conditions.

Abstract: Ionic gel polymer electrolytes for rechargeable polymer batteries. In preferred forms, a gel polymer precursor electrolyte is formed by dissolving a gelling agent into organic liquid electrolytes, and then gelling the precursor in situ at elevated temperature after pouring it into a battery case that contains a cathode, an anode and a separator. The gel polymer electrolytes exhibit excellent ionic conductivity of up to about 10−2 S/cm and voltage stability for lithium rechargeable batteries.
