Described herein are materials for use in electrolytes that provide a number of desirable characteristics when implemented within batteries, such as high stability during battery cycling up to high temperatures, high voltages, high discharge capacity, high coulombic efficiency, and excellent retention of discharge capacity and coulombic efficiency over several cycles of charging and discharging. In some embodiments, a high voltage electrolyte includes a base electrolyte and a set of additive compounds, which impart these desirable performance characteristics.

Electrolyte solutions for high energy cathode materials and methods for use

A composition for forming an electrode. The composition includes a hybrid active material compound doped with a dopant. The hybrid active material comprises the reaction product of a metal fluoride compound and a metal complex. A method of making the composition is included.

High energy materials for a battery and methods for making and use

A composition for forming an electrode. The composition includes a metal fluoride compound doped with a dopant. The addition of the dopant: (i) improves the bulk conductivity of the composition as compared to the undoped metal fluoride compound; (ii) changes the bandgap of the composition as compared to the undoped metal fluoride compound; or (iii) induces the formation of a conductive metallic network. A method of making the composition is included.

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

A composition for forming an electrode. The composition includes a metal fluoride, such as copper fluoride, and a matrix material. The matrix material adds capacity to the electrode. The copper fluoride compound is characterized by a first voltage range in which the copper fluoride compound is electrochemically active and the matrix material characterized by a second voltage range in which the matrix material is electrochemically active and substantially stable. A method for forming the composition is included.

An electrolyte solution comprising an additive wherein the additive is not substantially consumed during charge and discharge cycles of the electrochemical cell. Additives include Lewis acids, electron-rich transition metal complexes, and electron deficient pi-conjugated systems.

Electrolyte materials for batteries and methods for use

An electrode for an electrochemical cell including a metal fluoride containing active electrode material and an intrinsically conductive coating wherein the coating is applied to the active electrode material by heating the mixture for a time and at a temperature that limits degradation of the cathode active material. The active material can be a hybrid material formed from the reaction of a metal fluoride and a metal complex.

High energy cathode for a battery

Combinations of additives for use in electrolyte formulations that provide a number of desirable characteristics when implemented within batteries, such as reduction, suppression, and/or inhibition of undesirable gas generation over several cycles of charging and discharging, in some cases during operation at high temperature and in some cases during high temperature storage.

Electrolyte formulations for gas suppression and methods of use

An electrode for an electrochemical cell including an active electrode material and an intrinsically conductive coating wherein the coating is applied to the active electrode material by heating the mixture for a time and at a temperature that limits degradation of the cathode active material.
