Rectangular alumina ceramic perforated battery holder

The rectangular alumina ceramic perforated battery holder is a high-performance ceramic component designed specifically for new energy battery systems. It uses high-purity alumina ceramic (Al ₂ O3 content ≥ 99.5%) as the substrate and is made through precision dry pressing and cold sintering processes.
Core features:
High strength and wear resistance: The Rockwell hardness reaches HRA85-90, and the wear resistance is 266 times that of manganese steel. It can withstand long-term mechanical friction and vibration, extending the service life of the battery pack.
Excellent insulation performance: withstand voltage strength ≥ 5000V, volume resistivity>10 ¹⁴Ω· cm, effectively preventing internal short circuits in the battery pack and ensuring the safety of high-voltage systems.
High temperature resistance and corrosion resistance: It can withstand temperatures ranging from -196 ℃ to 2000 ℃ and has strong corrosion resistance to chemicals such as electrolytes and fluorides, making it suitable for extreme working environments.
Lightweight design: With a density of only 3.5g/cm ³, it reduces weight by 50% compared to metal components and lowers the overall energy consumption of the battery pack.
Structural innovation: The main body is a rectangular base with precision positioning holes and heat dissipation holes distributed on the surface, with an aperture error of ≤± 0.02mm, supporting quick installation and efficient thermal management.

Application field

1. New energy vehicle battery system
   Battery module fixed bracket: replaces traditional metal brackets, solves the problem of poor contact caused by metal expansion in high temperature environments, and improves the stability of battery pack structure.
   High voltage insulation lining: used at the connection between the positive and negative electrodes of the battery to prevent high-voltage breakdown, and has passed ISO 6469-3 electric vehicle safety standard certification.
   Liquid cooled plate thermal conductive base: Paired with alumina ceramic coated liquid cooled plate, the thermal conductivity coefficient reaches 20W/m · K, which is three times higher than aluminum alloy, achieving uniform heat dissipation of the battery pack.
   Case: After a leading new energy vehicle company adopted this battery holder, the battery pack life was extended from 8 years to 12 years, and the failure rate decreased by 72%.
2. Energy storage power stations and 5G base stations
   Tiered utilization battery sorting fixture: As a battery capacity testing fixture, its electrolyte corrosion resistance extends the equipment maintenance cycle to 3 years, reducing the cost by 40% compared to plastic fixtures.
   UPS uninterruptible power supply insulation base: maintains dimensional stability within a wide temperature range of -40 ℃ to 85 ℃, solving the problem of traditional epoxy resin base cracking.
3. Aerospace and Special Equipment
   Satellite power system insulation bracket: Passed NASA air release test (ASTM E595), with a mass loss rate of less than 1% in vacuum environment, meeting space grade reliability requirements.
   Deep sea probe battery compartment liner: With a pressure resistance depth of 11000 meters and a compressive strength of over 300MPa, it ensures electrical safety in extreme pressure environments.

Customized service

1. Structural customization
   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.
2. 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.
