While India is rapidly building battery cell giga-factories, over 90% of active cathode powders—the most critical and expensive component of a lithium-ion cell—are imported from overseas. Cathode Active Material (CAM) and its chemical precursor (pCAM) represent the missing link in India's battery self-reliance roadmap.
Under the ACC Battery Storage PLI Scheme, localizing cathode precursor synthesis is a national priority. This guide details chemical co-precipitation, high-temperature calcination, plant setup costs, and commercial profitability for establishing a CAM precursor plant in India for 2026.
48% Value Capture: Cathode material represents nearly half the monetary value of an EV battery cell. Establishing domestic pCAM co-precipitation and CAM calcination lines captures the highest profit pool in the battery supply chain.
1. Manufacturing Technology: pCAM Co-Precipitation & Calcination
CAM manufacturing proceeds through two distinct chemical engineering operations:
- Step 1: pCAM Co-Precipitation: High-purity Nickel, Cobalt, and Manganese sulfate solutions are metered into Continuous Stirred-Tank Reactors (CSTR) with NaOH and Ammonia. Precise pH (11.2 ± 0.1) control yields dense spherical [Ni0.8Mn0.1Co0.1](OH)2 precursor particles.
- Step 2: Thermal Calcination with Lithium/Iron: pCAM powder is dry-blended with Lithium Hydroxide (LiOH) or Lithium Carbonate (Li2CO3) and fired inside a roller hearth kiln at 750°C–900°C under pure oxygen atmosphere, forming crystalline NCM 811 CAM powder.

Frequently Asked Questions (FAQs)
What is Cathode Active Material (CAM) and why is it the most valuable part of a battery cell?
Cathode Active Material (CAM)—such as NCM 811 (Nickel Cobalt Manganese) or LFP (Lithium Iron Phosphate)—is the active powder coated onto cathode foils. CAM accounts for 45% to 55% of the total raw material cost of an electric vehicle battery cell.
What is the precursor (pCAM) co-precipitation process?
pCAM is the un-lithiated nickel-manganese-cobalt hydroxide precursor. It is synthesized by co-precipitating metal sulfate solutions with sodium hydroxide (NaOH) inside CSTR reactors under precise pH and temperature control, forming spherical micro-particles.
What is the capital requirement for a 5,000-ton-per-year CAM/pCAM plant in India?
Establishing a commercial 5,000 Ton/year pCAM synthesis and high-temperature rotary calcination plant costs between ₹55 Crore and ₹140 Crore.
How does the ACC PLI scheme mandate Domestic Value Addition (DVA) for cathode materials?
The Ministry of Heavy Industries' Advanced Chemistry Cell (ACC) PLI scheme requires battery giga-factories to achieve 60% domestic content by Year 5, forcing battery makers to localize CAM and pCAM procurement from domestic chemical processors.
What is the growth outlook for CAM demand in India by 2030?
With 50+ GWh of battery giga-factories under construction in India, domestic demand for cathode active materials is projected to exceed 80,000 Metric Tons annually by 2030.
