There is no direct reaction between tributyl carbonate and lithium batteries, but tributyl carbonate can be used as one of the electrolytes in lithium-ion batteries. In lithium-ion batteries, tributyl carbonate is mixed with other organic solvents to improve the electrochemical performance and stability of the battery. Tributyl carbonate can be used as a solvent in lithium-ion batteries to facilitate the transfer of lithium ions between positive and negative electrodes, thereby enabling charging and discharging of the battery.
The main components of lithium battery electrolyte
Propylene oxideThe relationship with lithium batteries is that Without propylene oxide, lithium cannot be produced Battery. Since propylene oxide is one of the raw materials needed for lithium batteries, propylene oxideOpylene is the electrolytic solvent of lithium batteries, and propylene oxide is also one of the important raw materials for the production of dimethyl carbonate used in lithium batteries.
The production of dimethyl carbonate, the main component of lithium battery electrolyte, uses propylene oxide as the main raw material. One ton of dimethyl carbonate requires 0.6 tons of propylene oxide, and of course methanol and carbon are used. dioxide.
Applications of propylene oxide
Propylene oxide is mainly used to produce polyether polyols, propylene glycol and various types of nonionic surfactants, including polyether polyols are used to produce polyurethane Important raw materials for foams, insulation materials, elastomers, adhesives and coatings, various nonionic surfactants are widely usedUsed in petroleum, chemicals, pesticides, textiles, daily chemicals and other industries. At the same time, propylene oxide also provides an important basis for chemical raw materials. .
The main components of lithium battery electrolyte include solvents, solutes, additives and other raw materials.
The electrolyte is primarily responsible for the conduction of conductive ions between the positive and negative electrodes, but it also plays a key role in energy density, lifespan, power density, safety performance, wide temperature. application, etc. drums. The effect is called blood battery. In battery applications, the electrolyte must meet performance indicators such as high conductivity, good thermal stability, high chemical stability,wide electrochemical window, a wide operating temperature range and good safety.
Solvents, solutes, additives and other raw materials are prepared in proportion and under certain conditions. The quality proportions of the three raw materials are 80-85%, 10-12% and 3-5% respectively, and the cost proportions are 25-30%, 40-50% and 10%. 30% respectively.
Identification of lithium batteries
General nickel cadmium batteries are 500 mAh or 600 mAh, and nickel hydrogen batteries do not than 800 to 900 mAh while lithium-ion; Cell phone batteries have a capacity of 1300-1400 mAh, so the lithium battery is fully charged and can be used 1.5 times longer than the nickel-hydrogen battery and about 3.0 times longer long as the nickel-cadmium battery. If you notice that the operating timeIf the lithium-ion cell phone battery you purchased does not last as long as advertised or specified in the manual, it may be counterfeit.
Genuine batteries even have wear-resistant surfaces and are made of P Material C, no brittleness; Counterfeit batteries do not have an anti-wear surface or are too rough and are made from recycled materials, which are prone to fragility. If a nickel-cadmium or nickel-hydrogen battery pack is used to simulate a lithium-ion cell phone battery pack, it must be made up of five individual cells. The charging voltage of a single battery generally does not exceed 1.55V and total. the battery pack voltage does not exceed 7.75 V. When the total charge voltage of the battery pack is less than 8.0 V, it may be a nickel-cadmium or nickel-hydrogen battery.
