The application of high vacuum hot press furnaces in the new energy industry is mainly reflected in the preparation of electrode materials, synthesis of solid-state battery electrolytes, processing of hydrogen energy materials, and optimization of photovoltaic modules. The following is a specific analysis:
Preparation of electrode materials
In the field of new energy vehicle batteries, high vacuum hot pressing furnaces can be used for the preparation of electrode materials. Processing electrode materials in a vacuum hot pressing environment can optimize the microstructure of the materials, improve their conductivity, specific surface area, and stability. For example, removing moisture and volatile impurities from materials, improving material crystallinity and microstructure, appropriate temperature and pressure can help enhance the chemical bonds inside the material, thereby improving conductivity and stability, extending battery life, enhancing safety, and ultimately improving the charging and discharging performance and cycle life of new energy vehicle batteries.
Synthesis of Solid State Battery Electrolyte
In the field of solid-state batteries, high vacuum hot pressing furnaces can be used for hot pressing sintering of garnet type (LLZO) and sulfide based solid electrolytes. High voltage promotes the formation of ion conduction phases, high vacuum avoids lithium loss, improves ion conductivity (>10 ⁻ ³ S/cm) and interface stability, meeting the needs of the next generation of high-energy density batteries.
Hydrogen energy material processing
In the field of hydrogen energy, high vacuum hot pressing furnaces can be used for hot pressing of bipolar plates (graphite/metal composites) for proton exchange membrane fuel cells (PEMFC). Realize material densification and conductivity optimization under high temperature and high pressure, reduce contact resistance (<10 m Ω· cm ²), improve battery efficiency, and promote the commercialization process of hydrogen fuel cells.
Optimization of photovoltaic modules
In the field of photovoltaics, high vacuum hot pressing furnaces can be used to prepare key materials for solar panels, such as by precisely controlling temperature and pressure, improving the purity and crystalline quality of materials, reducing impurities and defects, and thereby improving photoelectric conversion efficiency.
