摘要： Prelithiation methods and fast charging lithium ion cell are provided, which combine high energy density and high power density. Several structural and chemical modifications are disclosed to enable combination of features that achieve both goals simultaneously in fast charging cells having long cycling lifetime. The cells have anodes with high content of Si, Ge and/or Sn as principal anode material, and cathodes providing a relatively low C/A ratio, with the anodes being prelithiated to have a high lithium content, provided by a prelithiation algorithm. Disclosed algorithms determine lithium content achieved through prelithiation by optimizing the electrolyte to increase cycling lifetime, adjusting energy density with respect to other cell parameters, and possibly reducing the C/A ratio to maintain the required cycling lifetime.

摘要： An energy storage device has all components, e.g. anode, electrolyte, and cathode contained and sealed with a trench in a substrate. Various methods and structures are disclosed for sealing the components. In some embodiments, a sealer or sealing layer seals the components. One embodiment uses a tension clamp to contain the components with additional pressure. Another embodiment uses a cathode structure cup which is held in place in the substrate via sidewall trench features. Different external connections to the device are disclosed. The invention enables full three-dimensional components to be created and contained entirely within the substrate during assembly, curing, galvanic cycling and other manufacturing processes and provides improved sealing of the components during device operation.

摘要： Square section liquid metal batteries (LMBs) with a grid device to suppress instabilities of fluids. The LMBs include a shell, negative current collector, negative material, metallic nets/plates, grid device, electrolyte, positive material, rectangular holes on partitions of grid device, and positive current collector. The positive material, electrolyte, and negative material are filled in the shell and automatically stratified from bottom to top according to the density from large to small. The negative current collector is linked with negative material, and the positive current collector is linked with positive material. The grid device is composed of partitions which cross each other and pass through the negative material, the electrolyte vertically in sequence, and extend inside the positive material. There are rectangular holes opened on the grid device, and the vertical height of each rectangular hole is larger than the biggest displacement of electrolyte during charging and discharging processes.
