Abstract: An efficiency engine identifies container sizes for containers of a workload and allocates the containers across server clusters and nodes based on peak resource usage requirements of the containers. Runtime feedback signals are generated from monitors within the containers indicative of a quality of service and resource usage. A decision engine can identify a bin packing action to take based upon the runtime feedback signals, and a control plane can perform the identified bin packing actions to adjust bin packing based upon the runtime feedback signals. Also, adaptive adjustment can be performed based on feedback signals and using a prediction engine.

Abstract: A battery includes a plurality of arranged battery cells; and a pressure regulating apparatus, including a body portion and a regulating valve, where the body portion is arranged between adjacent battery cells, a gas pipeline being formed in the body portion, and the regulating valve is arranged in the gas pipeline and configured to regulate pressure in the gas pipeline so as to adjust a gap between adjacent battery cells.

Abstract: A secondary battery, including a negative electrode plate and an electrolyte are provided. In some embodiments, the negative electrode plate includes a negative electrode current collector and a negative electrode active substance layer, a first metal oxide layer, and a second metal ion adsorption layer that are sequentially arranged on at least one surface of the negative electrode current collector; the first metal oxide is selected from at least one of manganese dioxide, molybdenum oxide, magnesium oxide, aluminum oxide, and phosphorus pentoxide; and the electrolyte contains second metal ions. In the secondary battery provided in this application, the first metal oxide layer is provided on the negative electrode plate, and the second metal ion adsorption layer is formed on a negative electrode to serve as a protective layer, thereby inhibiting decomposition of electrolytes and improving cycling performance and rate performance of battery cells.
