A non-aqueous electrolyte includes an ionic electrolyte salt, and a non-aqueous electrolyte solvent that includes a mixture of siloxane or a silane or a mixture thereof, a sulfone, and a fluorinated ether or fluorinated ester or a mixture thereof, an ionic liquid, or a carbonate.
摘要:
The electrolyte includes a cyclic polysiloxane having one or more side chains that each includes a poly(alkylene oxide) moiety and a spacer. Each spacer is positioned between the poly(alkylene oxide) moiety and a silicon on the main chain of the polysiloxane.

An electrolyte includes an alkali metal salt; an aprotic solvent; and a redox shuttle additive including an aromatic compound having at least one aromatic ring fused with at least one non-aromatic ring, the aromatic ring having two or more oxygen or phosphorus-containing substituents.
摘要:
An electrode includes a binder and an electroactive material, wherein the binder includes a polymer including a linear polysiloxane or a cyclic polysiloxane. The polymer may be generally represented by Formula I:
摘要:
An autonomous battery shutdown system includes a battery including an anode and a cathode, and an electrolyte composition between the anode and the cathode. The electrolyte composition includes an ionically conductive liquid containing lithium ions, and temperature-sensitive particles including a polymer having a melting temperature between 60° C. and 120° C. When the temperature of the battery exceeds 120° C., the temperature-sensitive particles form an ion barrier that traverses the battery. The resulting shutdown battery may have a specific charge capacity that is more than 98% lower than the specific charge capacity of the original battery.

摘要:
The electrolyte includes one or more salts and a silane. The silane has a silicon linked to one or more first substituents that each include a poly(alkylene oxide) moiety or a cyclic carbonate moiety. The silane can be linked to four of the first substituents. Alternately, the silane can be linked to the one or more first substituents and one or more second substituents that each exclude both a poly(alkylene oxide) moiety and a cyclic carbonate moiety.
摘要:
One example of the disiloxanes include a backbone with a first silicon and a second silicon. The first silicon is linked to a first substituent selected from a group consisting of: a first side chain that includes a cyclic carbonate moiety; a first side chain that includes a poly(alkylene oxide) moiety; and a first cross link links the disiloxane to a second siloxane and that includes a poly(alkylene oxide) moiety. In some instance, the second silicon is linked to a second substituent selected from a group consisting of: a second side chain that includes a cyclic carbonate moiety, and a second side chain that includes a poly(alkylene oxide) moiety.
