The vacuum drying oven is designed for drying heat sensitive, easily decomposable and easily oxidizable materials. It can be filled with an inert gas, which can make some ingredients with complex ingredients dry quickly. Scope of application: High Temperature Vacuum drying ovens are widely used in research and application fields such as biochemistry, chemical pharmacy, medical and health, agricult...

The lithium-air battery is a new type of high-capacity lithium-ion battery developed by the Japan Industrial Technology Research Institute and the Japan Society for the Promotion of Science (JSPS). The battery uses lithium metal as the negative electrode, oxygen in the air as the positive electrode, and the electrodes are separated by a solid electrolyte; the negative electrode uses an&n...

Although high-voltage lithium battery materials are getting more and more attention, these high-voltage anode materials are still unable to achieve good results in practical production and application. The biggest limiting factor is that the electrochemical stability window of the carbonate-based electrolyte is low. When the battery voltage reaches about 4．5（vs．Li/Li＋）, the electrolyte begins to p...

The battery separator plays a major role in lithium ion battery conduction lithium ions and isolation between the positive and negative electrode electronic contact. It is an important component to support the battery to complete the electrochemical process of charge and discharge. In the use of lithium batteries, when the battery overcharge or at higher temperatures, the separator ...

One of the most successful lithium ion systems is the cathode combination of nickel-manganese-Cobalt (NMC). Like lithium manganate, the system can be customised for use as an energy or power battery. For example, the NMC in the 18650 battery under moderate load has a capacity of about 2,800mAh and can provide 4A to 5A discharge currents. The same type of NMC, optimized for a specific power, has a ...

NCA cathode materials batteries have high specific energy, good specific power and long service life similar to NMC cathode battery. But the disadvantages of NCA cathode batteries are low safety and high cost. NCA is a further development of lithium nickel oxide. The addition of aluminum gives the battery greater chemical stability. High energy and power density and good service life make NCA a ca...

Currently, achieving high capacity energy density and power density has become the focus of expanding Lithium batteries applications to large-scale energy storage systems. Therefore, high load level and harsh calendering process are needed in the electrode manufacturing process to meet the requirements of high volume energy density of batteries. Although the electrode fabrication process is highly...

In the structure of lithium-ion battery cells, the battery tab is the metal conductor that leads from the cathode and anode electrodes of the cell, and the complete battery tab is mainly composed of high temperature insulating adhesive and metal conductive substrate. High-temperature insulating adhesive is the insulating part on the battery tabs, for pouch cell, its role is to prevent the short ci...
