Key Factors Driving Growth

• Annual 18% increase in local lithium battery production capacity (2020-2024)
• 30% lower labor costs compared to Chinese manufacturers
• Proximity to Middle Eastern and African markets

"Karachi's battery exports grew 142% in Q1 2024 alone, signaling strong market confidence." - Pakistan Trade Development Authority Report

The Manufacturing Process Breakdown

Understanding the cylindrical lithium battery process helps buyers evaluate supplier capabilities:

Stage 1: Electrode Preparation

• Coating: Precision application of active materials
• Calendering: Achieving uniform thickness (±1μm tolerance)

Stage 2: Cell Assembly

Component	Specification	Quality Control Check
Separator	20-25μm thickness	Porosity testing
Electrolyte	1.0-1.2M LiPF6	Moisture content <20ppm

Stage 3: Formation & Aging

Manufacturers like EK SOLAR utilize advanced formation cycles that improve cycle life by 15-20% compared to standard processes.
