A few days ago, Gree Titanium "high safety large magnification energy storage system key technology research and development and application" project, won the second prize of Guangdong Science and Technology Science and Technology Progress Award, with hard power, Gree titanium has become a "key" to solve the obstacles to the development of new energy batteries.
Under the background of global carbon neutrality acceleration, Gree Titanium has opened up a market in the energy storage market with the absolute advantages of "high safety, large magnification, wide temperature resistance and long life".
With the lithium titanate battery of Gree titanium "high safety and high magnification energy storage system key technology research and development and application", following the identification of "international leading" in 2020, it recently won the Guangdong Science and Technology Award Science and Technology Progress Award.
It is worth mentioning that Gree Titanium, which continues to "do big things in the new energy industry", has the halo of "national manufacturing single champion product" on its head, and its R&D and production of 14-meter airport shuttle bus has perfectly passed the certification of the designated testing agency of the Civil Aviation Administration, officially obtained the airport vehicle access, and has become one of the few new energy models in civil airports.
This gold, which was once "buried in the sand", eventually turned sand into gold.
"Titanium", with advantages
On November 11, 2021, the company officially changed its name to "Gree Titanium New Energy Co., Ltd." This change of name is named after the word "titanium", which also highlights the "titanium" advantage of lithium titanate batteries. In the era when new energy market technology is king, lithium titanate has opened up a different new energy market with its unique advantages.
Relevant industry insiders said that the energy storage system is the first to consider its safety performance, and Gree titanium's lithium titanate battery has become the leader in the safety performance of the battery industry, and gree titanium will usher in a huge development space in the future.
It is reported that compared with other lithium-ion batteries, the Gree titanium battery material known as "zero strain material" has a higher potential for lithium metal, avoiding the generation of lithium dendrites that cause short circuits or worsen the negative electrode during the overcharge process, and the safety and stability are better.
Therefore, the Gree titanium battery can be charged and discharged normally from minus 50 ° C to 60 ° C, and there is no need to be equipped with an additional power battery heating system when charging in winter, which solves the problem of battery fire from the root cause. At the same time, Gree titanium batteries carried out experiments such as electric drills, cutting, and acupuncture, and there was no explosion and fire.
In this regard, Chen Qingquan, an academician of the Chinese Academy of Engineering, also said in public, "After years of practice, Gree titanium batteries are one of the best batteries in the field of lithium batteries. ”
At the same time, the advantages of long life of Gree titanium batteries are also very prominent. Traditional lithium batteries generally use graphite as the negative electrode material, graphite is a two-dimensional layered structure, lithium ion de-embedding process, the volume change rate is high, resulting in a decrease in cycle life. The lithium ion of lithium titanate batteries is called "zero strain material" to change this criticism.
The general number of ordinary lead-acid batteries is 3,000 times, while Gree titanium batteries can be recharged and discharged up to 30,000 times, and according to the calculation of 1,000 times of charge and discharge per year, the service life can be as high as 30 years.
In addition, the lithium ion diffusion coefficient of lithium titanate is high and the electrochemical reaction is fast, so that Gree titanium batteries can achieve stable high-power fast charging. According to the official website of Gree Titanium, the charge and discharge rate of Gree titanium batteries is as high as 10C, which can instantly provide large-magnification power input and output, and can support rapid full charge in 8-15 minutes.
In other words, even in extremely cold conditions, the battery can be charged in just a few minutes, for which some netizens joked in gree's forum: "In the future of the popularity of charging piles, the speed of charging is about to catch up with the speed of refueling!" ”
In summary, as a new star in the new energy market, Gree Titanium, although the latecomers are on top, but the rock-solid stability and safety performance have undoubtedly become the "key" to solve the obstacles to the development of new energy batteries.
The real "quality" deserves to be supported
"Energy Storage + New Energy" territory
From the current point of view, the energy storage gap in the mainland is still very large. The previously issued "Guiding Opinions on New Energy Storage" for the first time clarified and quantified the development goals of the energy storage industry at the national level, and it is expected that the installed capacity of new energy storage will reach more than 30 million kilowatts (30GW+) by 2025. In the next five years, the size of the new energy storage market will expand to 10 times the current level, with an average annual compound growth rate of more than 55%.
Gree Titanium is as far-sighted as ever, and is ahead of the layout in the energy storage track.
In 2021, a batch of Gree titanium communication base station energy storage systems officially landed in Liangshan Prefecture, Ganzi Prefecture, Aba Prefecture and other high-altitude areas in Sichuan. Gree titanium in high altitude, ultra-low temperature regional communication station with safety, extreme weather resistance, and long life advantages to become a favorable guarantee for communication base stations.
Gree titanium containerized energy storage system successfully landed in Tibet Langkazi 50MWp photovoltaic power station, abandoning the criticism of the instability and indirectness of new energy power generation, and solving the problem of "abandoning light and curtailing electricity".
Tibet's solar energy resources rank first in the country, Langkazi County is located in the northern foothills of the middle section of the Himalayas, 4500 meters above sea level, belongs to the subarctic plateau climate, Gree titanium technology team for langkazi photovoltaic power station abandonment and other issues of innovative technology exploration, successfully developed a suitable for high altitude areas of the light storage system Gree titanium container energy storage system.
It is worth mentioning that at present, Gree Titanium has entered many overseas projects such as Denmark and Finland, and serves as a mobile charging station in various scenarios such as wind power plants and photovoltaic power generation.
At present, with the increasing shortage of energy resources, the completion of Gree Titanium's diversified fusion green base station has also boosted the goals of "carbon peaking" and "carbon neutrality", and continues to carry out in-depth layout in the field of energy storage with broad prospects.
