Oqitop New Material Limited’ nickel foamutilizes advanced deep-processing technology to transform metallic nickel into a material with a three-dimensional, fully porous network structure. Pore count per inch (PPI) is a key parameter determining the phySic<\/b>al and electrochemical properties of a material. Nickel foams commonly used in standard battery research typically have high PPI values, such as 95\u00b110 PPI or 110 PPI.<\/p>\n

The PPI 110\u00a0\u0627\u0644\u0645\u0648\u0627\u062f<\/b>\u00a0delivered to Asia in November 2025 falls within this standard fine-pore, high-PPI range, with a pore size of approximately 0.25 mm.<\/p>\n

This material boasts an extremely low bulk density (only 1\/5 that of solid nickel) due to its high porosity of up to 98%. For a 1.6 mm thick product, the specification for the November delivery is 420 g\/m\u00b2. This density value falls within the industry standard range (typically 300 g\/m\u00b2-5000 g\/m\u00b2) and is slightly higher than common 110 PPI specifications (e.g., 320 g\/m\u00b2 or 350 g\/m\u00b2).<\/p>\n

High areal density means a thicker nickel skeleton, resulting in enhanced mechanical strength and conductivity, which is crucial for handling stresses during high-speed rolling and long-term battery cycling.<\/p>\n

In terms of mechanical properties, the nickel foam must be able to withstand the stresses of electrode coating, rolling, and stacking processes.<\/p>\n

Industry standards require a longitudinal tensile strength >125 N\/mm\u00b2 and a minimum elongation of 5%. Due to the flattening process during manufacturing, the tensile properties of\u00a0nickel foam\u00a0can exhibit anisotropy; therefore, strict control of longitudinal and transverse tensile strength is essential to ensure the continuity and output of high-performance production lines.<\/p>\n

Meanwhile, high purity (>99.7%) is a fundamental guarantee of battery performance.<\/p>\n

We ensure quality through comprehensive testing using specialized equipment such as spectrometers and tensile testing machines. Even if common oxides such as nickel oxide (NiO) are present, they can be removed by annealing in a hydrogen furnace to ensure electrochemical activity.<\/p>\n

Thank you for your attention!<\/p>\n
