The application of polysilazane in the field of new energy vehicles will encounter the following challenges:
At the technical level
The preparation process is complex: the preparation process of polysilazane is difficult, the technical threshold is high, and there are problems such as complex reaction products and low molar mass, resulting in low production efficiency and difficulty in meeting the material requirements for large-scale production of new energy vehicles.
Material stability issue: Some polysilazanes are relatively active and have high reactivity with water, polar compounds, oxygen, etc. They require special conditions during storage and transportation, which increases the difficulty and cost of supply chain management. And in the complex usage environment of new energy vehicles, such as high temperature, high humidity, high vibration, etc., polysilazane may undergo performance changes, affecting its effectiveness.
Compatibility challenge with battery system: In battery applications, polysilazane, as an electrode binder or solid electrolyte, needs to have good compatibility with the positive and negative electrode materials, electrolyte, etc. in the battery, otherwise it may cause internal side reactions and reduce the performance and safety of the battery.
Difficulty in matching thermal management: Although polysilazane can be used as a heat dissipation coating and insulation material for thermal management systems, to achieve precise matching with new energy vehicle thermal management systems and ensure effective heat dissipation and insulation under different operating conditions, in-depth research and optimization design are needed. Meanwhile, the thermal expansion coefficient and other parameters of the ceramic material after pyrolysis need to be matched with the automotive components, otherwise problems such as cracking and detachment may occur.
Optimization of electromagnetic shielding performance: When used for electromagnetic shielding in electronic and electrical systems, polysilazane needs to further optimize its electromagnetic shielding performance to meet the increasingly high electromagnetic compatibility requirements of new energy vehicles, while also ensuring that its electrical insulation performance is not affected.
At the cost level
High production costs: The production process of polysilazane may involve expensive raw materials, complex equipment, and processes, resulting in high production costs. This puts certain economic pressure on the large-scale application of polysilazane in the cost sensitive field of new energy vehicles, which may limit its market promotion.
The issue of recycling costs: After the scrapping of new energy vehicles, the cost of recycling and processing polysilazane materials is relatively high. At present, there is a lack of effective recycling technology and system. How to recycle polysilazane materials from waste cars and carry out further processing and reuse is an urgent problem to be solved.
Market and industry level
Insufficient market awareness: Compared to traditional automotive materials, polysilazane is a new type of material, and the automotive industry's understanding of its performance and advantages is not sufficient. More market promotion and application demonstrations are needed to improve the awareness and acceptance of polysilazane by automotive manufacturers, component suppliers, and others.
Lack of industry standards and regulations: Currently, there is a lack of unified industry standards and regulations for the application of polysilazane in the field of new energy vehicles, which leads to certain uncertainties in material selection, testing, quality control, and other aspects, which is not conducive to the large-scale application and promotion of polysilazane in the new energy vehicle industry.
High competition pressure: There are numerous material suppliers in the field of new energy vehicles, and the competition is fierce. Polysilazane needs to compete for market share with other traditional and new materials, such as traditional metal materials, polymer materials, and other emerging high-performance composite materials.
At the intellectual property level
Patent barrier restrictions: Intellectual property rights related to polysilazane technology are mainly held by enterprises in developed countries such as Europe and America. Domestic enterprises may face the risk of patent infringement when developing and applying polysilazane, which limits their development and innovation in this field.
