Nowadays it is the season of eating dates. We often eat fresh dates, dried dates, candied dates, and drunk dates. Jujube is not only sweet and juicy, but also rich in nutrients, with the highest content of vitamin C, 243 mg of vitamin C per 100 grams. In addition, it contains essential human carotene far more than other dates. However, fresh jujube will lose its crisp taste at room temperature for a few days. To facilitate preservation, fresh dates can be dried into dried dates. However, when the dates are dried, there is less vitamin C dissolved in water, which also has a great influence on other nutrients. However, the content of calcium in dried dates is higher than that of fresh dates. Drunken dates are mellow, crispy and pleasant, and can be stored for a long period of time, but the nutritional loss of drunk dates is even greater, and vitamin C is almost completely destroyed. However, drunk jujube because of the large amount of water loss after drying, and after soaking in wine, mineral content increased, so drunk date calcium content is the best of these kinds of jujube products, containing 75 mg per 100 grams. Making candied dates into candied fruit is another way to preserve them, but candied dates have a higher calorie content of 78.9 grams per 100 grams of carbohydrates. Fresh dates are best eaten raw and are good for nutrient absorption. The dried dates are more suitable for porridge or soup and can release nutrients well. Compared with fresh dates and dry dates, candied dates have the least nutrients and the highest sugar content. They are also best used for porridge and can dilute the sugar concentration in candied dates. The use of red dates for diet therapy in autumn is also very effective, the following recommended two red dates diet recipe: 60 grams of jujube, 200 grams of celery washed plus boiled, daily sub-times to eat, have prevention and treatment of high blood pressure, dizziness, headache 5 grams of red dates, white fungus 10 grams, amount of sugar, red dates, white fungus wash, stew until cooked soft, add sugar every morning and evening food, can prevent lack of effort caused by neurasthenia, to achieve the role of yin blood and soothe the nerves. Jujube is a weak constitution, nourishing nursed back to health. However, jujube skin is not easy to digest, must be chewed slowly. At the same time, eating too much and eating too much can cause hyperacidity and bloating
Lithium hexafluorophosphate is one of the most used electrolyte salt in the production of lithium ion batteries. Electrolyte Lithium Hexafluorophosphate for Lithium-ion Batteries has the ability of dissolving in binary and ternary solvents which cyclic carbonates and linear carbonates can be given as example. After lithium hexafluorophosphate dissolves in these solvents, it shows high electrolytic conductivity and thermal stability which is a desired property for lithium ion batteries.
The main use of LiPF6 is in commercial secondary batteries, an application that exploits its high solubility in non aqueous, polar solvents. Specifically, solutions of lithium hexafluorophosphate in carbonate blends of ethylene carbonate, dimethyl carbonate, diethyl carbonate and/or ethyl methyl carbonate, with a small amount of one or many additives such as fluoroethylene carbonate and vinylene carbonate, serve as state-of-the-art electrolytes in lithium-ion batteries.[6][7] This application also exploits the inertness of the hexafluorophosphate anion toward strong reducing agents, such as lithium metal.
