Abstract:

A battery is disclosed that includes an anode, a graded interface layer disposed on the anode, a cathode positioned opposite to the anode, an electrolyte, and a separator. The anode may output lithium ions during cycling of the battery. A graded interface layer may be disposed on the anode and include a tin fluoride layer. A tin-lithium alloy region may form between the tin fluoride layer and the anode. The tin-lithium alloy region may produce a lithium fluoride uniformly dispersed between the anode and the tin fluoride layer during operational cycling of the battery. The electrolyte may disperse throughout the cathode and the anode. The separator may be positioned between the anode and cathode. In some aspects, the battery may also include lithium electrodeposited on one or more exposed surfaces of the anode.

Abstract:

A composition of matter suitable for incorporation into a battery electrode is disclosed. In some implementations, the composition of matter may include pores that may be defined in size or shape by several carbonaceous particles. Each of the particles may have multiple regions such that adjacent regions are separated from each other by some of the pores. Deformable regions may be distributed throughout a perimeter of each of the particles, for example, to accommodate coalescence of multiple adjacent particles. The composition of matter may also include a plurality of aggregates and a plurality of agglomerates, where each aggregate includes a multitude of the particles joined together, and each agglomerate includes a multitude of the aggregates joined together.

Abstract:

Batteries including an electrolyte with a ternary solvent package are disclosed. In various implementations, a lithium-sulfur battery may include a cathode, an anode, and an electrolyte include a ternary solvent package. The anode may be positioned opposite to the cathode. The cathode may include a plurality of regions. Each region may be defined by two or more core-shell structures adjacent to and in contact with each other. The electrolyte may be interspersed throughout the cathode and be in contact with the anode. The ternary solvent package may include 1,2-Dimethoxyethane (DME), 1,3-Dioxolane (DOL), tetraethylene glycol dimethyl ether (TEGDME), and/or one or more additives, such as lithium nitrate (LiNO), and 4,4′-thiobisbenzenethiol (TBT) or 2-mercaptobenzothiazole (MBT), and approximately 0.01 mol of dissolved lithium bis(trifluoromethanesulfonyl)imide (LiTFSI).
