A composite solid state electrolyte comprises a polymer electrolyte material, a ceramic ion conductor, and a functionalized coupling agent selected to be compatible with the ceramic ion conductor and the bulk polymer compound. The polymer electrolyte material comprises a bulk polymer compound and a lithium salt. The functionalized coupling agent has a backbone that is structurally similar to the bulk polymer compound.

Composite solid state electrolyte and lithium ion battery containing the same

Additives to electrolytes that enable the formation of comparatively more robust SEI films on silicon anodes. The SEI films in these embodiments are seen to be more robust in part because the batteries containing these materials have higher coulombic efficiency and longer cycle life than comparable batteries without such additives.

Electrolyte formulations for electrochemical cells containing a silicon electrode

A solid-state electrolyte includes a lithium salt, a lithium ion-conducting inorganic material, a polymer, and a coupling agent. The coupling agent bonds the lithium ion-conducting inorganic material to the polymer.

Solid electrolyte compositions

Electrolyte solutions including additives or combinations of additives that provide low temperature performance and high temperature stability in lithium ion battery cells.

Electrolyte formulations for lithium ion batteries

Additives to electrolytes that enable the formation of comparatively more robust SEI films on silicon anodes. The SEI films in these embodiments are seen to be more robust in part because the batteries containing these materials have higher coulombic efficiency and longer cycle life than comparable batteries without such additives. The additives preferably contain a nitrate group.

A solid-state electrolyte including a polymer, which can be ion-conducting or non-conducting; an ion-conducting inorganic material; a lithium salt; an additive salt and optionally a coupling agent.

Electrolyte formulations including additives or combinations of additives. The electrolyte formulations are useful in lithium ion battery cells having lithium titanate anodes. The electrolyte formulations provide low temperature power performance and high temperature stability in such lithium ion battery cells.

A battery including an anode, a cathode, a separator, and a liquid electrolyte including a lithium salt, a non-aqueous solvent, and an additive compound including a functionalized matrix having a polymer or copolymer or silica. The cathode material can be an NMC or LCO material. The electrode formed from the cathode or anode material can include a matrix additive. The matrix additive can be adhered to the separator or other inert component of the battery.

Electrolyte additives and electrode materials for high temperature and high voltage operation

An electrode formulation including a polymer, which can be ion-conducting or non-conducting; an ion-conducting inorganic material; a lithium salt; and optionally an additive salt.

Electrode compositions for solid-state batteries

An electrolyte formulation including additive compounds, additive salts, or combinations thereof to improve both low temperature and high temperature performance of lithium ion batteries as compared to conventional electrolytes. Some of these embodiments further include solvents in the electrolyte solution.

Electrolyte formulations

Particulate LMFP cathode materials having high manganese contents and small amounts of dopant metals are disclosed. These cathode materials are made by milling a mixture of precursor materials in a wet or dry milling process. Preferably, off-stoichiometric amounts of starting materials are used to make the cathode materials. Unlike other high manganese LMFP materials, these cathode materials provide high specific capacities, very good cycle life and high energies even at high discharge rates.

LMFP cathode materials with improved electrochemical performance

Additives to electrolytes that enable the formation of comparatively more robust SEI films on silicon anodes. The SEI films in these embodiments are seen to be more robust in part because the batteries containing these materials have higher coulombic efficiency and longer cycle life than comparable batteries without such additives. The additives preferably contain a dicarbonate group or are an organo-metallic hydride.
