摘要： Electrode or electrolyte additives for energy storage devices comprising symmetrical or asymmetrical alkylsulfonyl imide or cyclic alkylene sulfonylimide salts are disclosed. The energy storage device comprises a first electrode and a second electrode, wherein at least one of the first electrode and the second electrode is a Si-based electrode, a separator between the first electrode and the second electrode, and an electrolyte composition. Symmetrical or asymmetrical alkylsulfonyl imide or cyclic alkylene sulfonylimide salts may serve as additives to the electrodes or to the electrolyte composition, or both.

摘要： Systems and methods are provided for control of thermal transfer during electrode pyrolysis based processing. An apparatus for processing battery electrodes may include a core configured for use in forming an electrode roll and a thermal rod. The core is configured to engage a sheet including electrode material applied on a current collector, specifically by rolling the sheet on the core to create concentric alternating layers of electrode material and current collector around an internal space formed by the core. The thermal rod is configured for engaging the electrode roll via the internal space of the core such that, once engaged, at least a portion of the thermal rod is disposed within the concentric alternating layers of electrode material and current collector. The thermal rod is configured to provide thermal transfer into the electrode roll via the core during processing of the electrode roll, with the processing including applying pyrolysis.
