カスタマイズ・サービス
- 構造のカスタマイズ
Hole design: Supports customization of any aperture (0.5mm-50mm), hole spacing (accuracy ± 0.01mm), and hole type (round hole, square hole, irregular hole).
Size expansion: It can produce up to 1200mm × 600mm ultra large battery holders, meeting the needs of containerized battery clusters in energy storage power stations.
Surface treatment: Provide processes such as mirror polishing (Ra ≤ 0.1 μ m) and metalized coating (Ni/Au/Ag) to enhance welding adhesion or conductivity. - Material upgrade
High thermal conductivity type: Adding aluminum nitride (AlN) or silicon carbide (SiC) particles, the thermal conductivity is increased to 35W/m · K, suitable for fast charging battery packs.
Antistatic type: Half conductive ceramics prepared by doping zirconia (ZrO ₂), with surface resistivity controlled between 10 ⁶ -10 ⁹ Ω, to prevent static electricity accumulation and potential safety hazards.
Addressing industry pain points
Corrosion of metal components: In an electrolyte environment, metal supports are prone to intergranular corrosion, leading to an increase in contact resistance. The chemical inertness of alumina ceramics can completely avoid this risk.
High temperature failure of plastic components: Traditional PPS/PEEK plastics soften and deform above 150 ℃, while ceramic components have a melting point greater than 2000 ℃, ensuring structural integrity under extreme working conditions.
The cost of composite materials is high: Carbon Fiber Reinforced Polymer (CFRP) has a cost three times that of alumina ceramics and is difficult to recycle. Ceramic components are 100% recyclable and meet ESG standards.
