Abstract: A rechargeable lithium battery is provided. The battery includes an anode comprising a polymer-matrix electrolyte (PME) and an anode active material, a cathode comprising a PME and a cathode active material and a PME comprising an electrolyte polymer, a lithium salt and an electrolyte solvent. The PME is positioned between the anode and the cathode and directly contacts the anode and cathode to form a battery cell. The polymer-matrix electrolyte interpenetrates into the adjacent anode and cathode to form an integral structure.

Abstract: Provided herein is a high-volume continuous roll-to-roll method for manufacturing dimensionally stable, large format, high performance solid batteries using high lithium-ion conducting polymer matrix electrolyte (PME). The batteries can include a cathode layer sandwich with a thin contiguous PME layer across the anode and a high conducting PME in both the anode and cathode structures. The batteries can also retain a thin PME layer that functions as solid-state electrolyte between the cathode and anode thus maintaining continuity among the layers, resulting in minimal interface resistance and stronger structural integrity.

The sleeve is constructed from a material that acts as an insulator at relatively low temperatures and that acts as a conductor at relatively high temperatures.

Abstract: An improved lithium-ion or lithium-polymer battery that is capacity-fade resistant. The battery includes an anode comprised of graphite where density of the graphite is in a range from 1.2 to 1.5 g/c3; and the battery further has a cathode that is comprised of LiNiO2 present at a density in a range from 3.0 to 3.3 g/c3. The battery also includes an electrolyte and a separator between the anode and cathode, and the separator is coated with PVDF such that the anode, cathode, and separator are held together to form the electricity-producing battery. The ratio by weight of LiNiO2 to graphite present in the battery is preferably no greater than 2.0 to 1.

Abstract: A lithium-ion battery having at least an anode that includes phenol formaldehyde in a range of 0.1% to 10% by weight as a binder material. The phenol formaldehyde, or a mixture of phenol formaldehyde with polyvinylidene fluoride (PVDF), is used as a binding material in a Li-ion battery negative electrode to decrease the exothermic reaction of the battery during charging and discharging, which accordingly lessens the risk of thermal runaway and rupture of the battery.
