an inorganic compound, Li2CO3, as a colorless monoclinic crystal or white powder. The density of 2.11 g/cm3. Melting point is 618 ℃. Dissolve in dilute acid. Slightly soluble in water, greater solubility in cold water than in hot water. Insoluble in alcohol and acetone. Can be used for ceramics, medicine, catalyst, etc. Commonly used lithium ion battery materials.
Functions and Uses
Lithium carbonate has significant bay mania is effect, can improve the emotional obstacle of energy schizophrenia, heal amount had no effect on normal energy activity, when the mechanism may be related to acute brain nerve synapse norepinephrine released and promote to learn again, cells have a role to increase peripheral area, this drug is small doses for uterine fibroids annexation of menorrhagia is bound to heal, Small dose can also be used for acute bacterial dysentery, lithium salt has no sedative effect, generally for severe acute manic patients with chlorpromazine first used together, acute symptom control and then maintained with lithium carbonate alone.
The general dose of mania is 0.125 ~ 0.5g every time, 3 times a day, starting with a smaller dose, can be gradually added to 1.5 ~ 2g, or even 3G, maintain the daily 0.75 ~ 1.5g.
Granulocytopenia, regeneration of obstructing anemia oral, each 300mg a day 3 times a month after multiple diseases: the top of the menstrual day after taking 0.6g, 0.3g a day, divided into 3 times, a total of 3 days of acute bacterial dysenteric 0.1g each, 3 times a day the first dose doubled
Dizziness, nausea, vomiting, abdominal pain, diarrhea and other side effects
Matters needing attention
Savings poisoning, there can be encephalopathy syndrome (cognitive confusion tremor epilepsy) and even coma, shock, kidney damage, the above situation immediately stop medicine, intravenous infusion of aminophylline, to promote the excretion of lithium.
Sodium salt can promote lithium by kidney cleaning, during the medication should maintain normal salt intake, the elderly lithium excretion is slow, easy to accumulate poisoning, pay attention to adjust the dose, this drug should not be used with Yantong Xikang, otherwise it can lead to high blood lithium concentration and poisoning. Contraindicated in patients with cardiac nephropathy and electrolyte disorder.
Various materials of high purity lithium salt; Raw materials containing lithium single crystal; Used in optical special glass, enamel industry, medicine, catalyst, color phosphor; Lithium ion battery material.
Application analysis of lithium phosphate battery
One of the main aspects is to reduce the cost. When the vehicle is produced, the cost of the battery is high, accounting for about 50% of the cost of the vehicle, plus subsidies and so on. In terms of the price advantage, the price of the vehicle has a smaller advantage compared with the fuel car. The cost of lithium phosphate battery is much lower than that of ternary lithium battery. For vehicle production, the selection of lithium phosphate battery can save the production cost of vehicle.
Then the second aspect is to improve the stability of the battery and increase the safety function of the battery. For lithium iron phosphate battery, it is more stable than three lithium batteries in function, and the advantage is more obvious than three lithium batteries. The spontaneous combustion temperature of lithium iron phosphate battery is 800℃, and the three lithium battery is 200℃. Obviously, it is difficult for vehicles equipped with lithium iron phosphate batteries to spontaneously combate. From this aspect, the safety function of vehicles is greatly improved.
The third aspect is that switching to lithium phosphate batteries can also prepare for the production capacity of vehicles. In terms of production, the material of the internal motor of lithium iron phosphate batteries is easier to produce than that of ternary lithium batteries. With the improvement of the industrial chain of lithium phosphate batteries, there is no need to worry about the production capacity. Generally speaking, the replacement of lithium phosphate batteries is mainly to reduce the cost of vehicles and improve the safety function of vehicle batteries. In the fierce competition of electric vehicle market, who first reduce the cost of power battery, but also to meet people's demand for long range, high safety, long life. I'm sure I'll get a bigger slice of the pie at the mall.
