The battery cells include at least a first battery cell and a second battery cell. The connecting unit includes a first positive connecting part configured to detachably connect a positive terminal of the first battery cell and electrically connected to the positive terminal of the first battery cell; and a first negative connecting part configured to detachably connect a negative terminal of the second battery cell and electrically connected to the negative terminal of the second battery cell. The first negative connecting part is connected to the first positive connecting part.

Abstract: The present invention provides a rechargeable alkaline battery with enhanced cycling stability and coulombic efficiency. The battery includes a cathode prepared with a cathode material and connected to a first terminal, an anode prepared with an anode material and connected to a second terminal, a hydroxide electrolyte with a higher concentration, and at least one porous separator positioned between the anode and the cathode. The hydroxide electrolyte inhibits hydrogen evolution from approximately 20% to less than 5% of an overall reaction. When cycled at 40% DOD under charging and discharging at 15 mA/cmZn2, the rechargeable alkaline battery exhibits a cycling stability with a capacity retention of >80% after 290 cycles.

Abstract: A method for purifying a Fomes officinalis polysaccharide by sequential simulated moving chromatography is provided by the present application, relating to the technical field of biological extraction. The method includes the following steps: step 1, leaching Fomes officinalis to obtain a polysaccharide extractive solution; step 2, purifying the polysaccharide extractive solution by sequential simulated moving chromatography to obtain a purified solution; and step 3, subjecting the purified solution to a treatment of refining and removing impurities, followed by concentrating and drying to obtain the Fomes officinalis polysaccharide. The Fomes officinalis polysaccharide prepared the method is applied in preparing products for promoting NO production by macrophages.

Abstract: In a method of charging a battery, a charging control device obtains a battery parameter that includes an electrode parameter of the battery and one or more of a structure parameter, a manufacturing process parameter, an electrical parameter, an electrolyte parameter, a diaphragm parameter, and a thermophysical parameter of the battery. The charging control device inputs the battery parameter input into a battery model represented by an ordinary differential equation to obtain a safe charging boundary value of the battery in n cycles, where n is greater than or equal to 2 and less than or equal to N, N is a cycle life of the battery, and the n cycles refer to n cycles selected from 0 to N cycles. The safe charging boundary value is a maximum charging current in which no lithium plating occurs on the battery in different states of charge SOCs and at different temperatures.

Abstract: Techniques for predicting a next company and next title of a user are disclosed herein. In some embodiments, an encoder is used for encoding a representation of the user's profile. The encoding includes accessing discrete entities comprising context information included in the user's profile, constructing a plurality of embedding vectors from the context information, and generating a context vector from the plurality of embedding vectors. The plurality of embedding vectors including a skill embedding vector, a school embedding vector, and a location embedding vector. A decoder is for decoding a career path from the context vector. The decoding includes applying a long short-term memory (LSTM) model to the context vector to generate perform the prediction of the user's next company and next title for presentation in a user interface.
