摘要: Systems and methods for optimal planning and real-time control of energy storage systems for multiple simultaneous applications are provided. Energy storage applications can be analyzed for relevant metrics such as profitability and impact on the functionality of the electric grid, subject to system-wide and energy storage hardware constraints. The optimal amount of storage capacity and the optimal operating strategy can then be derived for each application and be prioritized according to a dispatch stack, which can be statically or dynamically updated according to data forecasts. Embodiments can consist of both planning tools and real-time control algorithms.

摘要: Embodiments described herein relate generally to apparatuses and processes for forming semi-solid electrodes having high active solids loading by removing excess electrolyte. In some embodiments, the semi-solid electrode material can be formed by mixing an active material and, optionally, a conductive material in a liquid electrolyte to form a suspension. In some embodiments, the semi-solid electrode material can be disposed onto a current collector to form an intermediate electrode. In some embodiments, the semi-solid electrode material can have a first composition in which the ratio of electrolyte to active material is between about 10:1 and about 1:1. In some embodiments, a method for converting the semi-solid electrode material from the first composition into the second composition includes removing a portion of the electrolyte from the semi-solid electrode material. In some embodiments, the method includes mechanically compressing the intermediate electrode to remove the portion of electrolyte from the semi-solid electrode material.

摘要: Embodiments described herein relate generally to systems and methods for continuously and/or semi-continuously manufacturing electrochemical cells with semi-solid electrodes. In some embodiments, a method can include mixing an active material, a conductive material, and an electrolyte to form a semi-solid electrode material. The method further includes drawing a vacuum on the semi-solid electrode material, compressing the semi-solid electrode material to form an electrode brick, and dispensing a portion of the electrode brick onto a current collector via a dispensation device to form an electrode. In some embodiments, the current collector is disposed on a pouch material. In some embodiments, the dispensation device includes a top blade for top edge control and two side plates for side edge control. In some embodiments, the method can further include conveying the electrode through the top blade and the two side plates to shape the electrode.
