Looking at the world, the unstable climate system is intensified. Since the summer, there have been high -temperature heat waves in the northern hemisphere. France, Spain, the United Kingdom, the United States, Japan and other cities have set a high temperature record.

The high -temperature heat waves that swept the world made people truly feel the impact of climate warming. What cannot be ignored is that as global warming intensifies, extreme weather events will become more frequent and destructive.

In order to save our common home, reducing greenhouse gas emissions and slowing climate warming process has become a global consensus. In this context, Chinese enterprises actively implement the concept of low -carbon development, and help the energy structure transformation and green supply chain construction through technological innovation to further promote the high -quality development of my country's economy. Below, enjoy:

01 | Energy structure transformation

With the alarm bells that respond to climate change, the energy pattern is also quietly changing. The construction and development of the clean energy system represented by photovoltaic and hydrogen energy is of great significance for the transformation and upgrading of the energy structure and the response to climate change.

Due to the characteristics of cleaning, efficient, safe, and sustainable, hydrogen energy is regarded as one of the most developed energy types in the 21st century, and has huge potential in the field of transportation and industrial production. However, due to the late development of hydrogen energy in my country, there are still insufficient in the links of hydrogen, storage, transportation, hydrogenation, and application. For example, as a breakthrough in the application of fuel cells as the application of the hydrogen energy industry scenario, the production of its core material proton exchange membrane has a long -term "card neck" problem.

In this regard, after more than ten years of scientific research, Suzhou Kerun New Materials, the company invested by Lianhong Group, successfully solved the core membrane materials in the field of "card neck" in the field of "stuck neck" in the field of liquid liquid storage batteries and hydrogen fuel cells. More than 40 technical patents have achieved domestic autonomy of general fluorosamulfenate proton exchange membranes. The liquid storage energy battery industry provides more than 90%of domestic proton exchange membrane products; it is also one of the only two companies in China that can produce and supply hydrogen fuel cells with proton exchange membranes in batches. The backbone of industrialization.

The photovoltaic industry has dual attributes of energy and industry, and is an important way to crack the energy security crisis and achieve green sustainable development. With the in -depth implementation of the "double carbon" strategy, photovoltaic development has ushered in a new round of development worldwide. However, as a key component of photovoltaic components, ethylene-ethyl-acetate-ethylene closer (EVA) import dependence is high, and domestic supply and demand gaps are obvious, thereby restricting the further development of the industry.

In this regard, some new material companies with technical advantages in China actively break through the pain points of the industry with independent innovation. Among them, Lenovo Holding Member Enterprise Lianhong New Science realized domestic alternative to photovoltaic EVA glue film, which greatly reduced its dependence on imported products and actively helped the domestic photovoltaic industry to continue to lead the world. In addition, Lianhong New Science also completed the "EVA Device Tube Tail Technology Upgrade Project" on March 25 this year, and successfully operated and put into operation on March 27. It is expected that the production of major products such as EVA in 2022 will increase year -on -year.

02 | Green Supply Chain Construction

As an important content and core link of green manufacturing, the green supply chain includes the entire process of life cycle of product life cycle from supply, logistics and consumption. In the context of the "dual carbon", enterprises should increase their awareness of carbon emissions in the supply chain link, and actively use green supply chain to strengthen the management of carbon supply.

In the practice of the green supply chain, core companies can usually play a fulcrum. The green supply chain created by them can often lead to the whole body. Related companies in the supply chain continue to improve the level of green development.

As a leading technology manufacturing company, Lenovo Group has been known for its excellent global supply chain operation capabilities. On the one hand, Lenovo Group realizes the road of low -carbon development with Lenovo's characteristics by creating energy -saving and environmentally friendly green products, promoting circular economy, promoting energy conservation and environmental protection, and green technology innovation. On the other hand, Lenovo Group actively exports technology, services and solutions to guide and drive the upstream and downstream of the entire industrial chain to achieve low -carbon transformation.

Green consumption is an important part of the low -carbon economy, and it is also an important measure for countries to deal with climate change. Green consumption requirements are based on low -carbon -based life cycles from raw materials production, consumer goods purchase, product use and final processing. Meet the consumer demand for green and low -carbon.

For example, in solving the problem of white pollution, the use of biodegradable plastic to replace traditional disposable plastic is considered the most effective solution. However, as an important biological degradable material, the production of polystumin (PLA) has certain technical difficulty, especially the synthesis technology of upstream raw material propylene esters still lacks effective industrialized solutions. In this regard, all sectors of society responded to and committed to driving the development of the entire industrial chain with their own technical advantages.

In June and September 2021, Lianhong New Sciences became the controlling shareholder of Jiangxi Science and Technology New Materials Co., Ltd. (hereinafter referred to as the "Science Institute Bio") through capital increase and equity acquisition, and invested in the construction of 130,000 tons/annual polyache acid project. Essence The Bio of the Academy of Sciences is mainly engaged in the R & D, production and sales of biodegradable materials PLA. It is one of the companies that have successfully developed "high -gloss pure lactic acid -high -gloss pure propyl ester -polymapilic acid" all -industry chain technology. PLA integrated production demonstration line and form a batch production capacity. In recent years, with the guidance and promotion of national policies, my country's new energy vehicle industry has achieved positive results. However, the rapidly growing new energy vehicle market has also brought the pressure on the processing of power batteries after the batches of power batteries. As an important part of the new energy vehicle industry, battery recycling is an important part of the large -circuit economy. Establishing a mature power battery recovery system can not only effectively solve environmental pollution problems, but also bring positive significance to alleviating the current and future supply chain raw materials.

At present, there are two main methods for the use of retirement power battery cycles, including steps of ladder utilization and disassembly recycling. In terms of step -by -step utilization, in response to the "when the battery should be retired again when the battery is retired", the company's investment in the company's investment in the company's key parameters can realize the full life cycle management of batteries from running to retirement through the battery key parameters. In terms of disassembling and recycling, the retired power lithium -ion battery of Hengchuang Rui invested by Junlian Capital Enterprise Hengchuang Rui Energy Reinforcement and Reinforcement Electrical Materials Detoxification Technology and Equipment Unit can achieve an organic matter removal rate of 98%. The dissipation of materials increased to 98.23%and 98.89%, respectively, effectively improving the recovery rate of materials and realizing resource reuse.

03 | Low -carbon technology independent innovation

Scientific and technological innovation is a key support for achieving the "double carbon" goal. In this regard, many national ministries and commissions have formulated the planning and supporting policies of green low -carbon technology innovation, and local governments have also actively introduced relevant measures. As the main body of scientific and technological innovation, enterprises urgently need to lay a comprehensive layout for achieving dual carbon targets, play a role of model leading, and develop and promote low -carbon technology.

As an earlier practice of ESG in China, Lenovo Group has achieved results in science and technology "carbon reduction", and achieved "green manufacturing" through warm water -cooled technology, "low -temperature tinnic paste" technology, and deep -cold nitrogen technology.

Temperature water cooling technology: It can solve the problem of high heat dissipation energy consumption of data centers, and achieve the perfect balance of cost and efficiency for enterprises. Compared with the air cooling method, Lenovo Group's warm water cold technology can reduce PUE (total energy consumption/IT equipment energy consumption) by 42%, and can also achieve energy recycling of energy according to the needs of different customers' business.

"Low -temperature tinnite" process: The temperature decreases by 70 degrees during welding, which not only speeds up the welding speed and increases production capacity, but also increases the reliability of the computer, and reduces the cost of electricity. Practice has proved that the low -temperature tin paste process can reduce the energy consumption and carbon emissions of the printing circuit board assembly process by 35%. In 2021, Lenovo Group had 20.6 million laptop shipments produced by low -temperature tinnodon craftsmanship to achieve annual carbon -saving 1087 tons.

Deep -cold nitrogen -making technology: The use of on -site gas+reserve liquid nitrogen dual system gas supply model, compared with the traditional gas -making method, greatly improves the reliability of nitrogen supply, and the power consumption is reduced by more than 50%. Wuhan Industrial Base saves more than 10,000 degrees of electricity.

As an important part of electric vehicles, the development of power battery technology and the improvement of performance are the core driving force to determine the long -term development of new energy vehicles, and it is also the key to promoting the "dual carbon" goals in the field of transportation. To this end, enterprises actively carry out business layout according to the development trend of power batteries in different periods, and improve their competitiveness while improving the performance of power batteries through technical breakthroughs.

Limited in the short term: iteration of materials+structural innovation. In terms of material iterations, Junlian Capital and Zhengqi Holdings jointly invested companies, Tai Tailai, actively promoted the middle test and mass production of new products such as silicon oxygen, silicon carbon, and hard carbon. In terms of structural innovation, the Ningde Times of Junlian Capital Institute Ningde Times passed the world's first moduleless (CTP) technology to simplify the module structure, which increased the volume efficiency of battery packs by 30%, reduced number of parts by 40%, improved production efficiency improved production efficiency. 50%, energy density exceeds 250Wh/kg, and the cost of battery packaged decreased by 10%-15%.

Long -term: development to solid -state batteries. The Ningde Times of Junlian Capital announced in early 2022 that two solid -state battery -related patents were announced, and they said that in the future, metal lithium will be used as negative electrode materials. In the end above. The company's investment in the company's investment in Tailan New Energy is based on a self -developed high -electronic oxide solid electrolyte material and electrolyte import process equipment. The performance indicators have achieved disruptive breakthroughs, reaching the world's leading level.

Long -term: sodium lithium complementary. The energy density of the first -generation sodium ion batteries developed by Junlian Capital Institute Ningde Times was as high as 160Wh/KG, breaking the global limit. In addition, Ningde Times also innovatively mixed with sodium ions and lithium ion batteries in a battery pack, and accurately controlled different battery systems through the BMS system.

On August 3, the China Meteorological Administration's Climate Change Center released the "China Climate Change Blue Book (2022)", which shows that the global warming trend is still continuing. China's temperature increase rate is higher than the global average level in the same period, which is the sensitivity of global climate change.Area.The current changes in climate and environment have become a common challenge for human beings. Further strengthening energy conservation and emission reduction work is the urgent needs of global climate change, and it is also the responsibility we must bear.As a key subject to achieve the "double carbon" goal, enterprises should adhere to the integration of green and low -carbon development into the entire process of production and operation. This is not only a manifestation of social responsibility, but also an urgent need for its own development.
