摘要： An example method of reducing short circuits from occurring in a battery can include providing a current collector coated with a safety layer. The method can include providing an electrochemically active material film on the safety layer such that the safety layer is configured to reduce exposure of the current collector to an opposing electrode. The method can also include adhering the electrochemically active material film to the current collector via the safety layer.

摘要： Various implementations of a method of forming an electrochemical cell include providing a first electrode, a second electrode, a separator between the first and second electrodes, and an electrolyte in a cell container. The first electrode can include silicon-dominant electrochemically active material. The silicon-dominant electrochemically active material can include greater than 50% silicon by weight. The method can also include exposing at least a part of the electrochemical cell to CO2, and forming a solid electrolyte interphase (SEI) layer on the first electrode using the CO2.

摘要： The present application describes the use of a solid electrolyte interphase (SEI) fluorinating precursor and/or an SEI fluorinating compound to coat an electrode material and create an artificial SEI layer. These modifications may increase surface passivation of the electrodes, SEI robustness, and structural stability of the silicon-containing electrodes.

摘要： Methods of forming electrodes are described. In some embodiments, the method can include providing a current collector. The method can also include providing a first carbon precursor on the current collector and providing a mixture on the first carbon precursor. The mixture can include a second carbon precursor and silicon particles. The method can further include pyrolysing the second carbon precursor to convert the second carbon precursor into one or more types of carbon phases to form a composite material. The one or more types of carbon phases can be a substantially continuous phase with the silicon particles distributed throughout the composite material. The method can also include pyrolysing the first carbon precursor to adhere the composite material to the current collector.
