Industry highlights
Steady growth in military spending and the high outlook of the military industry is expected to continue (Financial Associated Press)
China’s military budget in 2022 was 1.45 trillion yuan, a year-on-year increase of 7.1%, an increase of 0.3 percentage points over 2021, the first increase of more than 7% since 2019. In recent years, the growth of China’s military spending has basically kept pace with the growth of GDP. According to the GDP growth target of about 5.5% in 2022, the proportion of military expenditure in GDP is about 1.2%, which is still far from the world mainstream level of 2.4%.
Silicon carbon negative electrode has become the most promising next-generation lithium battery material. Tesla and Contemporary Amperex Technology Co.Limited(300750) have added weight one after another (Financial Associated Press)
Silicon carbon negative electrode has the advantages of high energy density and suitable discharge platform. It is one of the potential next generation negative electrode materials. In the past few years, due to the high price of products and the immature supporting industrial chain, the industrialization of silicon carbon negative electrode has not progressed as expected. However, since 2021, Tesla, Contemporary Amperex Technology Co.Limited(300750) and other enterprises have successively started mass production of power battery products using silicon carbon negative electrode, and some negative electrode enterprises have also begun to invest in the construction of silicon carbon negative electrode production line.
As an important part of lithium-ion battery, the use of high-capacity cathode materials can effectively improve the energy density of the whole battery. After decades of development, the actual specific capacity of the most commonly used graphite material can reach 360365mah / g, which is very close to the theoretical specific capacity (372mah / g). The continuous improvement of graphite negative electrode performance is very limited to the improvement of lithium-ion battery performance. Silicon based anode has the advantages of high energy density, wide distribution of raw materials and suitable discharge platform. It is considered to be a promising cathode material for the next generation of lithium ion batteries.
