New graphite film is launched, with grain size approximately 10,000 times that of traditional artificial graphite! There are less than 10 concept stocks.

According to the latest issue of the journal "Nature Communications" quoted by Science Daily, the Korea Institute of Basic Science has developed a groundbreaking method to produce millimeter-sized grains of graphite thin film that are mirror-like smooth, with grain sizes approximately 10,000 times that of traditional artificial graphite. Mechanical testing results show that the Young's modulus of the graphite thin film reaches 969 gigapascals, tensile strength is 1.29 gigapascals, approaching the theoretical limit of single crystal graphite, and the planar thermal conductivity is as high as 2034 watts per meter Kelvin, exceeding that of copper, with an electrical conductivity of 22500 Siemens per centimeter, breaking performance records of macroscopic artificial graphite. This achievement is expected to drive high-quality graphite applications in thermal management, electronic devices, advanced batteries, and other fields to a new level. According to Securities Times - Data Treasure statistics, there are less than 10 stocks related to the graphite business in the A-share market. As of the close on August 13, only 3 stocks had a trailing P/E ratio of less than 30 times, including Longbai Group, Betteray, and Zhongke Electric. Among the concept stocks that have already announced financial data, Daosi Technology and Zhongke Electric are in a state of increasing net profit. Zhongke Electric is expected to have a net profit of 232 million to 301 million yuan in the first half of 2025, an increase of 235% to 335% year-on-year. Daosi Technology has released its half-year report, achieving a net profit of 230 million yuan in the first half, an increase of 108.16% year-on-year.
