Abstract: A negative electrode material includes a dopant containing a first dopant and a second dopant, the first dopant contains a boron element, and the second dopant contains at least one selected from a group consisting of a nitrogen element, an oxygen element, a fluorine element, a phosphorus element, and a sulfur element. Two or more types of dopants are added in the particle producing process, so that the negative electrode material prepared has excellent high and low temperature cycle performance and rate performance. Furthermore, a carbonization coating process is omitted which is compatible with the preparation process of the conventional graphite negative electrode, thus the preparation process is simpler, the equipment required is less, and the cost is lower. A preparation method thereof is provided as well.

Abstract: A preparation method for a water-retaining nanoagent and applications thereof in a quick-frozen crustacean shrimp product, related to the technical field of food processing. The formula of the present invention comprises inulin, xylitol, carboxymethyl chitosan, pullulan, sodium tripolyphosphate, sodium chloride, and sodium alginate. The powder raw materials are mixed evenly with water and then go through a homogenizer, a colloid mill, and an ultrasound treatment to produce the water-retaining nanoagent. The method of the present invention also relates to applications of the freeze-proof water-retaining agent in freezing a crustacean aquatic product.
