Abstract: Storage material, for storing electrical energy by reduction or oxidation of an active component, comprises the active component in at least a reduced and/or oxidized form and a reactive framework structure that is capable of chemically integrating at least one form of the active component in the form of a mixed oxide or an alloy into the reactive framework structure during the charging or discharging process. In the case of an oxidic framework structure, said integration can occur by formation of at least one stable mixed oxide of the active component and an oxide from the framework structure. In the case of the metallic framework structure, said integration can occur by forming an alloy of active component and at least one metal of the framework structure.

Abstract: Provided herein are methods of forming solid-state ionically conductive composite materials that include particles of an inorganic phase in a matrix of an organic phase. The methods involve forming the composite materials from a precursor that is polymerized in-situ after being mixed with the particles. The polymerization occurs under applied pressure that causes particle-to-particle contact. In some embodiments, once polymerized, the applied pressure may be removed with the particles immobilized by the polymer matrix. In some implementations, the organic phase includes a cross-linked polymer network. Also provided are solid-state ionically conductive composite materials and batteries and other devices that incorporate them. In some embodiments, solid-state electrolytes including the ionically conductive solid-state composites are provided. In some embodiments, electrodes including the ionically conductive solid-state composites are provided.

Abstract: A lithium secondary battery having a positive electrode, a negative electrode, a separator and an electrolyte solution, in which the positive electrode contains a first active material and a second active material each capable of intercalating and deintercalating lithium. The first active material is in the state under which only deintercalation of lithium can be carried out in a battery reaction with the negative electrode immediately after assembly of the lithium secondary battery, and the second active material is in the state under which lithium can be intercalated in the battery reaction with the negative electrode immediately after assembly of the lithium secondary battery. The negative electrode contains metal lithium as an active material. The separator has a structure in which pores are three-dimensionally regularly arranged.

Abstract: The present invention relates to a lithium secondary battery which includes a non-aqueous electrolyte solution including lithium bis(fluorosulfonyl)imide (LiFSI) and a fluorobiphenyl compound, a positive electrode including a lithium-nickel-manganese-cobalt-based oxide as a positive electrode active material, a negative electrode, and a separator.In the lithium secondary battery including a non-aqueous electrolyte solution for a lithium secondary battery of the present invention, since the non-aqueous electrolyte solution may form a robust solid electrolyte interface (SEI) on the negative electrode during initial charge and may prevent decomposition of the surface of the positive electrode and an oxidation reaction of the electrolyte solution during a high-temperature cycle, excellent low-temperature output characteristics as well as improved high-temperature storage characteristics and life characteristics may be achieved.
