    摘要: A method and system for managing a battery system. The method including receiving at least one measured characteristic of the battery over a pre-defined time horizon from the at least one sensor, receiving at least one estimated characteristic of the battery from a electrochemical-based battery model based on differential algebraic equations, determining a cost function of a Moving Horizon Estimation based on the at least one measured characteristic and the at least one estimated characteristic, updating the electrochemical-based battery model based on the cost function, estimating at least one state of the at least one battery cell by applying the electrochemical-based battery model, and regulating at least one of charging or discharging of the battery based on the estimation of the at least one state of the at least one battery cell.

    摘要: An electrolyte structure for a battery cell includes a first portion configured as a thin film solid electrolyte and a second portion disposed adjacent to the first portion. The second portion includes a porous ceramic fiber material that contacts the electrolyte. The electrolyte structure is configured to be positioned between a positive electrode and a lithium metal negative electrode. The porous ceramic fiber material mechanically supports the electrolyte by strengthening it against internal and external stresses associated with fabrication and/or operation of the battery cell. The porous ceramic fiber material also provides a substrate on which the electrolyte is deposited, grown, or otherwise formed. In one embodiment, the second portion with the porous ceramic fiber material is configured to be removed after the electrolyte structure is positioned between the positive and negative electrodes. The electrolyte in one embodiment is formed from lithium phosphorous oxynitride (LiPON).

    摘要: An electrode configuration for a battery cell includes a positive electrode, a negative electrode, a separator interposed between the positive electrode and the negative electrode, and a low counter-ion permeability layer interposed between the separator and the positive electrode. The separator has a first permeability to counter-ions, which do not participate in the battery electrode reactions, and the low counter-ion permeability layer has a second permeability to the counter-ions that is less than the first permeability. The separator includes a first salt concentration adjacent to the low counter-ion permeability layer and a second salt concentration adjacent to the negative electrode, and the second salt concentration is greater than the first salt concentration.

    摘要: A battery management system comprising a processor and a memory storing instructions that, when executed by the processor, cause the battery management system to estimate one or more states of the battery by applying a battery model to account for physical parameters of a chemical composition of the battery based on one or more measured characteristics of the battery and the one or more estimated characteristics of the battery and regulate a first charging mode of the battery based on the estimation of the one or more states of the one or more battery cells and switch between the first charging mode and a second charging mode based on the estimation of the one or more states of the battery to allow for rapid charging of the battery.

    摘要: A battery, in particular a Lithium-ion battery, includes a cathode, anode, and electrolyte. The cathode includes a first substrate with solid cathode material, and a first amorphous coating above the first substrate that acts as a first artificial solid-electrolyte interface (“SEI”) layer for the first substrate. The anode includes a second substrate with solid anode material, and a second amorphous coating above the second substrate that acts as a second artificial SEI layer for the second substrate. The electrolyte is disposed directly between the first and second amorphous coatings. A method of producing battery includes using low temperature atomic layer deposition processes to deposit material on first and second substrates, respectively, to form first and second amorphous coatings. The method further includes arranging an electrolyte directly between the first and second amorphous coatings in order to form a battery.
