New Energy Industry

Pulished on Jan. 21, 2020

In recent years, new energy vehicles have been the focus of discussion in the automotive field. In 2017, the Ministry of Industry and Information Technology, the National Development and Reform Commission, and the Ministry of Science and Technology jointly issued the Medium- and Long-Term Development Plan for the Automotive Industry, and proposed that by 2020, several new energy automobile companies entering the world's top ten will be cultivated, and intelligent networks Connected cars are developing synchronously with the world. By 2025, the backbone of new energy vehicle companies in the world will further increase their influence and market share, and intelligent connected cars will enter the world's leading ranks. In 2016, the “Thirteenth Five-Year Plan” national new energy vehicle special project was launched, and it was proposed to significantly increase the proportion of new energy vehicles and new energy applications, and promote green and low-carbon industries such as new energy vehicles, new energy and energy conservation and environmental protection to become pillar industries. With the rise of a new round of technological revolution, the aggravation of the global energy crisis, and environmental problems caused by automobile emissions, intelligence, networking and new energy have become an inevitable trend in the development of the global automotive industry in the future.


With the continuous emergence of various new vehicles on the market, new thermal interface materials with different heat dissipation performance, safety protection performance, and low density and lightweight performance are required to match power battery packs. During the assembly and development process of power battery packs, for different battery packs with different design structures, different types of new thermal interface materials must be assisted. It affects the weight ratio of the battery pack to the entire vehicle and the cruising range. The development of new energy vehicles plays a crucial role.


On February 12, 2018, the four ministries of the Ministry of Finance, the Ministry of Industry and Information Technology, the Ministry of Science and Technology and the Development and Reform Commission jointly issued the "Notice on Adjusting and Perfecting the Financial Subsidy Policy for the Promotion and Application of New Energy Vehicles", confirming the previous market The speculation that energy vehicle subsidies will accelerate. The policy cancels the subsidies with a mileage of less than 150 kilometers, and the subsidy amounts below 300 kilometers have all dropped sharply. The subsidy amount for high mileage has increased without decreasing; the upper limit of the additional unit battery power subsidy does not exceed 1,200 yuan / kWh; the maximum energy The density index is set at 160wh / kg, which can get 1.2 times the subsidy, and steadily move towards the national plan of 260Wh / kg in 2020.


A small number of models currently meet this new policy standard. As a leader in the innovative functional materials industry, Hongfucheng has taken the lead in developing high-strength series, low-density series, high-impedance series and other products to assist battery pack manufacturers in completing lightweight design of PACKs to achieve higher energy density and longer mileage. purpose.
