The way to prepare graphene by CVD technology has been passed, and the whole team is still immersed in the joy of success. Just when everyone thought they could go to the celebration dinner, Dr. He Limin put forward new requirements to the team members: "The graphene film has been made, but now many universities and team laboratories can do it. What we need to do next is to do what they have not done. We need to do large-scale, high-quality, engineered graphene production! Only in this way can graphene materia

The development of lead-acid battery is limited, and even suffers some criticism. One important reason is the possible industrial pollution, which involves the recycling of waste batteries. Considering the need of China's commitment to building an "upgraded version" of the economy, accelerating economic transformation and upgrading, and accelerating the development of the circular economy, resource recovery has become a bottleneck that must be broken through in the lead-acid battery market, and also o

In recent years, building a resource conserving and environment-friendly society has gradually become the consensus of all countries, and the rapid economic development has a huge demand for electricity, making energy storage technology a topic of continuous concern and discussion among governments and industry. Professor level senior engineer from the Institute of Electrical Engineering and New Materials, Chinese Academy of Electric Power Sciences, said that at present, renewable energy has the characteristics

On June 3, 2015, under the guidance of the National Energy Administration and co sponsored by Zhongguancun Energy Storage Industry Technology Alliance (CNESA) and Dusseldorf Exhibition (Shanghai) Co., Ltd., the "Energy Storage International Summit 2015" was held in Beijing. At the sub forum of energy storage technology, Xu Xiaoxiong, a researcher of Ningbo Institute of Materials Technology and Engineering, CAS, delivered a keynote speech. The following is the content of the speech. Xu Xiaoxiong, Resear

As the saying goes, all martial arts in the world are fast but not broken. In today's efficient society where "time is money", "fast" is the king's way. For a long time, the slow charging speed has been a constraint to the development of new energy vehicles. In order to solve this problem, new energy vehicles have innovated two rapid power supply modes in the electric energy supply scheme: fast charging and power exchange. As the saying goes, literature is not the first, and martial a

In today's energy industry, the most popular star business is energy storage. When we talk about energy storage, it seems that everyone can say a few words, but most people can not clearly define the exact definition of energy storage. Then, the question arises - is energy storage really entering the spring, or is it trapped in an illusory foam? Since the end of last year, the news about energy storage has shown an explosive growth trend. The theme of various forums and forums has the shadow of energy sto

At the TEDA Forum just past, the Deputy Director of the Department of High tech Development and Industrialization of the Ministry of Science and Technology continued to disclose in advance the industrial focus at the end of the 13th Five Year Plan and during the 14th Five Year Plan. On the one hand, it focused on the key core technologies of hydrogen fuel cells for vehicles, as well as the research and development of core technologies such as hydrogen production, hydrogen storage and hydrogen refueling, and continu

Lithium battery application scenarios can be divided into consumption, power and energy storage. The earliest application is in mobile phones, laptops, digital cameras and other consumer products, which currently accounts for about half of the global shipments of all types of lithium batteries. With the increase of global demand for new energy vehicles, the proportion of power lithium batteries has increased year by year, accounting for more than 40% at present. Power batteries will become the main application scen

The "China Top 500 Enterprises Summit Forum" was held in Xi'an on September 1-2. The forum was hosted by the China Enterprise Confederation and the China Entrepreneur Association, hosted by the People's Government of Shaanxi Province, and co sponsored by the People's Government of Xi'an. The theme of the forum was "Striving for the World Class: the Development of Large Enterprises in a New Era". Liu Ke, Vice President of the National Friendship Association, Foreign Academician of
