2020 carbon nanotube conductive paste market size will break 70,000 tons At present, the domestic conductive agent materials mainly include conductive carbon black, conductive graphite, carbon nanotubes (CNT), graphene, etc. The new conductive agents (carbon nanotubes, graphene and their composite conductive agents) have higher conductivity and less proportion of addition. Its application scope and proportion are gradually expanding. In the next few years, China's new conductive agents, especially carbon nanotube conductive agents, will gradually replace traditional conductive agents. By 2020, the market size of carbon nanotube conductive paste will exceed 70,000 tons, mainly based on: 1) The new energy vehicle market continues to increase the requirements for fast charging performance of power batteries. With excellent electrical conductivity, the application range of carbon nanotube conductive agent will gradually expand; 2) The technology of carbon nanotube conductive agent gradually matures, the unit production efficiency and process automation are further optimized, and the price drops; 3)The industrialization of high-nickelization and silicon-based anodes has accelerated, and the demand for carbon nanotube conductive agents has increased.

Lithium-sulfur battery has taken an important step towards commercial viability Lithium-sulfur batteries are hailed as tomorrow's stars in battery technology. It is expected that a single charge will significantly increase the service life of mobile phones, electric vehicles and other products, and it is more environmentally friendly than current lithium-ion batteries. However, the life of lithium-sulfur batteries is not as long as that of lithium-ion batteries, and will deteriorate over time. A team of researchers at the Corkrel School of Engineering at the University of Texas at Austin has found a way to stabilize the most challenging parts of lithium-sulfur batteries, bringing the technology closer to commercial viability. The research results recently published by the research team in the "Joule" magazine show that an artificial layer containing tellurium is fabricated in situ inside the battery and covered with lithium metal, which can extend its life by four times. "The layer formed on the lithium surface allows it to operate without damaging the electrolyte and increases battery life." Said Amruth Bhargav, who and his graduate student Sanjay · Sanjay Nanda co-authored this paper. Solving the instability of this part of the battery is the key to extending its service life and promoting its application. Manselam said that lithium-sulfur batteries are currently the most suitable for devices that require light batteries. They can run for a long time on a single charge without requiring a large number of charging cycles, such as drones. But they have the potential to play an important role in expanding the use of electric vehicles and increasing the use of renewable energy. Mantheram said that the charging capacity of the positive and negative electrodes of lithium-sulfur batteries is 10 times that of today's lithium-ion batteries, which means that a single charge can provide more sustainable use. Sulphur is widely present as a by-product of the oil and gas industry, making the production cost of batteries low. Sulfur is also more environmentally friendly than the metal oxide materials used in lithium-ion batteries. Reported by Jack Yan AOTELEC BATTERY EQUIPMENT COMPANY 2020-4-29

How can Chinese power battery companies become global Tier1? For Tier 1 suppliers (Tier1), Benchmark's requirement is to be qualified to provide products to multinational automotive OEM / EV manufacturers outside of China; suppliers to the domestic electric vehicle market in China; annual cumulative production capacity> 5GWh. Based on this standard, there are only 6 companies that truly comply with Tier1, namely LG Chem, Panasonic Tesla, CATL, Samsung SDI, SKI and Vision AESC. Of these, only CATL and Vision AESC are Chinese battery companies. (AOTELEC is Chinese battery equipment manufacturer) -Level 1: Qualified to provide products to multinational automotive OEM / EV manufacturers outside of China China's domestic electric vehicle market supplier Cumulative annual production capacity> 5GWh (equivalent in evaluation) -Level 2: Not yet qualified to provide products to multinational automotive OEM / EV manufacturers outside of China Qualified to supply domestic electric vehicle manufacturers in China Eligible to provide non-electric vehicle applications Annual cumulative capacity> 1GWh (equivalent at the time of evaluation) -Level 3: Not yet qualified to provide the electric vehicle terminal market Annual cumulative capacity> 1GWh (equivalent at the time of evaluation) Main focus: Non-electric vehicle market, including portable and stationary After CATL and Prospect AESC, Chinese battery companies can only hope to be recognized by international auto companies if they truly cross the above-mentioned series of challenges, so as to truly realize the“transformation”of Chinese power battery companies to the global Tier 1.

New changes in the carbon nanotube market On April 1, Cabot officially completed the acquisition of Shenzhen Sanshun Nano New Materials Co., Ltd. at a price of 115 million US dollars (equivalent to approximately 800 million yuan), which was included in Cabot Special global energy materials business system management. After the acquisition was completed, Cabot became the only company in the world that covered all mainstream lithium battery conductive material. Research data shows that the shipments of carbon nanotubes have shown rapid growth in recent years. From 2015 to 2019, domestic carbon nanotube shipments increased from 0.83 million tons to 35,800 tons, and the growth trend is still maintained. In the field of power batteries, the current market penetration of carbon nanotube conductive agents has exceeded 50%. It is foreseeable that, on the one hand, the power battery giant is matching the needs of customers to deploy global production capacity. As the market penetration of carbon nanotubes in the field of power batteries continues to increase, the competition boundary of carbon nanotube head companies will continue to widen. On the other hand, as the power battery market is concentrated to giant companies, the market concentration of lithium battery composite conductive paste will be further improved, and the competition situation of carbon nanotube head companies will also become more intense. From the trend point of view, composite conductive materials will become an extremely important part of lithium battery additives. The industry is also continually searching for formulations of composite conductive agents combining carbon black, carbon nanotubes and graphene.

UK Harmony Energy invests in 49.5MW energy storage project Abstract: Harmony Energy said that the company currently has more than 500MW of large-scale battery storage system projects in the UK that are ready for construction or development. According to foreign media reports, British battery storage project developer HarmonyEnergy will continue to build a 49.5MW lithium battery storage system in Wiltshire after it has announced that it has obtained local planning permission for a grid-scale storage project. The system will provide balanced services for the National Grid, which is located on land near the Salisbury substation. It will connect to a 132kV distribution network, allowing more intermittent renewable energy from wind and solar projects to be installed on the grid. It is worth noting that in November last year, HarmonyEnergy also obtained the planning permission for the second 49.5MW lithium battery energy storage system at its CreykeBeck site, bringing the site's capacity to 99MW. In 2019, the global lithium battery energy storage market is rapidly heating up, including the deployment of lithium battery energy storage projects in Southeast Asia, Japan and South Korea, Australia, and Europe and the United States. Entering 2020, the global lithium battery energy storage market continues to maintain a rapid growth trend, especially in large-scale lithium battery energy storage projects in North America, Europe, Australia and China. This has provided good development opportunities for a number of lithium battery companies that have competitive strength in the energy storage market.
