In the lithium battery laboratory research process, we generally use a pipette to inject electrolyte into the battery. Pipettes can be used to take a small amount of liquid with high accuracy. Pipetting method: before pipetting, ensure that the pipette, tip, and liquid are at the same temperature. When pipetting the liquid, the pipette is held upright and the tip is inserted 2-3 mm below the surface. Before aspirating, you can first aspirate the liquid several times to wet the liquid suction nozzle. Our company can supply kinds of pipettes with different volume, manual model and electric model, they are widely used in lithium battery laboratory research. Thank you for your interested!

Lithium iron phosphate（LiFePo4） electrode materials are mainly used in various lithium ion batteries. It is characterized by large discharge capacity, low price, no toxicity, and no environmental pollution. Countries around the world are competing to achieve industrial production. However, its energy density is low, affecting the capacitance. The performance of lithium-ion batteries mainly depends on the positive and negative materials. Lithium iron phosphate（LiFePo4） as a positive electrode material for lithium-ion batteries has only appeared in recent years. The large-capacity Lithium iron phosphate（LiFePo4） battery developed in China was July 2005. Its safety performance and cycle life are incomparable to other materials, which are the most important technical indicators of power batteries. 1C charge and discharge cycle life of 2000 times. Single cell battery overcharge voltage 30V does not burn, puncture does not explode. Lithium iron phosphate cathode materials make large-capacity lithium-ion batteries easier to use in series. To meet the needs of frequent charging and discharging of electric vehicles. It has the advantages of non-toxic, non-polluting, good safety performance, wide source of raw materials, low price and long service life. It is an ideal cathode material for a new generation of lithium ion batteries.

Copper foam is a new type of multifunctional material with a large number of connected or non-connected pores evenly distributed in a copper matrix. The copper foam has good electrical conductivity and ductility, and has a lower preparation cost than the nickel foam, and has better electrical conductivity, and can be used for preparing a battery negative electrode (carrier) material, a catalyst carrier, and an electromagnetic shielding material. In particular, the use of copper foam as a base material for batteries as electrodes has some significant advantages, but its corrosion resistance is not as good as that of nickel, which limits its application.

Generally, the coating method needs to be considered from the following aspects, including: the number of layers coating, the thickness of the wet coating, the rheological properties of the coating liquid, the required coating accuracy, the coating substrate, the speed of coating, etc. How to choose the coating method suitable for the electrode slurry? In addition to the above factors, it is necessary to combine the specific conditions and characteristics of the electrode coating. Lithium-ion battery electrode coating features are: 1 double-sided single layer coating; 2 slurry wet coating is thick (100 ~ 300μm); 3 slurry is a non-Newtonian high viscosity fluid; 4 electrode coating accuracy requirements are high, and film coating accuracy is similar; 5 coated support is aluminum foil and copper foil with a thickness of 10 ~ 20μm; 6 The electrode coating speed is not high compared to the film coating speed. Considering the special requirements of the application of the electrode slurry, extrusion coating or roller coating is available.
