Microporous Copper Foil Aluminum Foil Solid-state Battery Lithium Battery For New Energy Power Battery-grade Current Collector Porous Punching

1. Product Overview

Our precision-engineered micro-perforated copper/aluminum foils are designed for next-generation solid-state and lithium-ion batteries. With customizable porosity (up to 40%) and zero burrs, these foils enhance electrolyte infiltration and electrode kinetics while maintaining structural integrity.

Key Applications:

Solid-state batteries
High-energy-density lithium batteries
Power batteries for EVs/ESS

2. Customizable Specifications

Parameter	Options
Thickness	8μm / 10μm / 12μm / >12μm
Width	187mm / 260mm / 350mm (OEM*)
Aperture	0.25mm / 0.35mm / 0.40mm (OEM*)
Spacing	0.6mm / 0.8mm (molded) / 1mm
Porosity	10%-40% (e.g., 17%: 0.35mm+0.8mm)

Note: Non-standard sizes require mold development.

3. Performance Advantages

A. Enhanced Electrode Compaction

Parameter	Conventional Foil	17% Microporous Foil
Ternary Cathode (15μm Al)
Thickness (μm)	99.6	97.06 (-2.55μm*)
Compaction Density (g/cm³)	3.31	3.41 (+3%)
Graphite Anode (10μm Cu)
Thickness (μm)	103.75	102.16 (-1.7μm*)
Compaction Density (g/cm³)	1.60	1.72 (+7.5%)

Theoretical thickness reduction due to porosity.

B. Superior Rate Performance

Metric	Conventional Foil	17% Microporous Foil
1C Capacity (mAh/g)	146.0	149.2 (+2.2%)
5C/1C Retention	39.20%	47.53% (+21.2%)

C. Lower Internal Resistance

Material	Internal Resistance (mΩ)
Conventional Foil	46.0
17% Microporous	39.8 (-13.5%)
