Other regions of the country have introduced other subsidy policies in the hope of stimulating consumption, and the preferential rate for the purchase tax on NEV purchase has been extended to the end of 2023. TrendForce points out that China initiated the phase-out of its NEV (new energy vehicle) subsidy at the start of 2023. This, in turn, caused the average price of electrolytes to drop by 11~15% MoM for the same month. Turning to electrolytes and related upstream materials, the average price of LiPF6 (lithium hexafluorophosphate) fell by 11% MoM for January. Nevertheless, the average prices of battery-grade lithium carbonate and lithium hydroxide both dipped below RMB 500,000 per metric tons. Compared with lithium carbonate, lithium hydroxide experienced a more moderate price slide. Lithium hydroxide also suffered a price drop, but the demand for this material was bolstered by orders from regions outside China. The average price of lithium carbonate, which is the most costly among the upstream materials related to cathodes, fell by 12% MoM. The decline was especially significant for upstream materials related to cathodes, cathode materials, and battery electrolytes. Real energy-saving, could achieve about 75% of energy efficiency.According to TrendForce’s latest research on the Li-ion (lithium ion) battery industry chain in China, there was an across-the-board decline in prices of upstream (raw) materials in January as participants in the industry chain were focusing on inventory consumption.It could be under the test of the highest temperature like 130℃, and it could also work without a problem under 3 meters of water. High-grade waterproof (IP68 grade), dust-proof, anticorrosion, UV resistance, V0 fireproofing grade.Strong heat dissipation, low power loss, low heat, long life span.This could meet the standard of export to EU countries and the USA. ▶ For the aluminum base, it has the function of anti-electromagnetic interference and anti-radiation. For this common cathode LED screen with aluminum bases with the same panel size, it is about 29 kg. For example, for a common anode LED screen with 960x960mm LED panel size, the weight is about 34 kg. As it is die-casting aluminum made, the flatness of the whole LED screen would be much better. This aluminum base would be the cooling fan for LED lamps and drive ICs. The heat on PCB would be transferred according to the aluminum base. ▶ The aluminum base of LED modules is adopted. Why the Heat of Common Cathode LED Display is Much Less?įrom the introduction of the common anode and common cathode supplying power, we could know the power used for a common cathode LED screen would be much lower than that of a common anode LED screen (regular LED screen), and the heat of the former would be much less than that of the latter. This makes little power loss and the heat is much less during the operation of an LED screen. For common cathode LED display, it is to supply power separately based on the voltage needed of red, green, blue LED lamps (it is about 2.5V for the red LED, while it is 3.8V for blue and green LEDs). As a result, this could cause a big power loss. ☛ Common anode LED display distributes a voltage more than 3.8V (5V for instance) to red, green, blue LED lamps to supply power together. For a common cathode LED display, just as mentioned above, it could make a low forward voltage drop. ☛ Common anode LED display current would get to the LED lamps from the PCB board and RGB LED lamps would supply power together, which could make a higher forward voltage drop. This would bring a low forward voltage drop and small conduction resistance. The current would get to the IC cathode from the LED lamps. This could distribute voltage and current to the red, green, blue LED lamps precisely. Common cathode means to supply electricity with the common cathode, which supplies power for red, green, blue separately. How could it be so excellent?įirst, we need to know what is the common cathode LED display. This method could save about 75% of energy. Recently, the power supply technology of the common cathode LED display has attracted much attention.
