Project Report for Lithium-Ion Battery
Lithium-ion battery manufacturing is a cutting-edge energy storage industry that manufactures cells, battery packs, and modules for electric vehicles, solar systems, consumer electronics, telecom equipment, and energy storage applications. Battery performance is heavily influenced by cell chemistry, assembly precision, and testing, hence the industry requires specialised machinery, quality-controlled materials, safety protocols, and technical knowledge.

Two Businesses Wearing the Same Name
“Lithium-ion battery manufacturing” refers to two distinct projects, and knowing which one you’re planning is more important here than in nearly any other topic on our site. Battery pack assembly entails procuring pre-made lithium-ion cells (mostly imported) and assembling them into full battery packs with battery management systems, casings, and connectors – a viable MSME-scale enterprise. Cell manufacture entails creating the actual lithium-ion cells from raw chemical inputs – a very new, gigawatt-scale industrial effort that even well-funded, established enterprises are finding extremely difficult to accomplish.
Being Honest About Cell Manufacturing's Real Scale
A small-scale battery pack assembly operation may be set up with around ₹5-15 crore investment, whereas cell manufacturing plants start at ₹50 crore and scale up to gigawatt-level output.
Even with the government’s flagship ₹18,100 crore PLI scheme for Advanced Chemistry Cell (ACC) manufacturing specifically designed to build domestic capacity, execution has been truly difficult. As of a reported January 2026 assessment, only about 2.8% of the scheme’s targeted 50 GWh capacity had been commissioned, years behind the original timeline, and that limited progress came from a single company.
This is not intended to discourage interest in the sector, but if large, well-capitalized, PLI-backed firms are still dealing with substantial supply chain and implementation hurdles, a new MSME entry should have a realistic picture of what is possible at their own scale.
Why India's Raw Material Dependence Matters for Your Planning
Lithium carbonate, cobalt sulphate, nickel sulphate, graphite, and electrolyte solvents are the primary raw materials used in cell manufacturing in India today, with the majority coming from China. This reliance is precisely why cell manufacture entails significant supply chain risk and complexity in addition to capital, and it is one of the reasons why the government has been actively investigating recycling as a technique for gradually building a more self-sufficient lithium supply. This similar import dependence is actually more manageable in a pack assembly firm because you’re getting finished cells (a more standardised, generally available commodity) rather than managing chemical-grade raw material supply chains yourself.
The Realistic Path for Smaller Players: Tier Supply, Not Direct PLI
If cell manufacturing piques your interest but full gigawatt-scale investment isn’t feasible, there’s a more accessible angle worth knowing: smaller manufacturers can work as Tier-1 or Tier-2 suppliers to large anchor cell manufacturers benefiting from PLI, rather than directly competing for the benefits. Separate MSME-focused schemes offered by the Ministry of MSME, such as collateral-free loans under CGTMSE and subsidised machinery loans under the Credit Linked Capital Subsidy Scheme, support this type of component or sub-assembly supply role, which is a far more accessible entry point than attempting cell production yourself.
How Battery Pack Assembly Actually Works
- Lithium-ion cells (cylindrical, prismatic, or pouch type, depending on your target application) are procured, primarily from established cell manufacturers, given India’s present import dependence.
- Cell testing and grading: incoming cells are evaluated for capacity, internal resistance, and consistency before assembly.
- Pack design and assembly—cells are organised into the target pack structure (series/parallel arrangement according to voltage and capacity requirements) and physically assembled
- A Battery Management System (BMS) is integrated to monitor and preserve the pack.
- Casing and connection fitting—The assembled pack is contained in its casing with appropriate connectors for its target use (EV, energy storage, consumer electronics).
- Safety and performance testing—testing to relevant safety standards (BIS CRS, AIS-156 for EV applications) before the pack is allowed for sale.
- Despatch to OEM/customer—packets are provided to their intended application maker, frequently after customer-specific qualification trials, which might take several months for big OEM relationships.
What You'll Need
Category | Typical Requirement (pack assembly route) |
Machinery | Cell testing/grading equipment, pack assembly line, BMS integration and testing setup |
Raw materials | Lithium-ion cells (sourced, largely imported), BMS components, casing materials |
Testing capability | Safety and performance testing to BIS CRS and, for EV applications, AIS-156 standards |
Infrastructure | Assembly facility with appropriate safety infrastructure given battery handling |
Licenses & Registrations
BIS certification under the Compulsory Registration Scheme (CRS) is required for battery products supplied in India. AIS-156 certification is necessary, primarily for EV battery applications. Udyam (MSME) Registration and GST Registration meet normal business standards. A Factory License is required at the appropriate scale, and given battery safety concerns, fire safety and Pollution Control Board approvals are critically needed.
Getting Your Report Bank-Ready
Because pack assembly and cell manufacturing represent such fundamentally distinct capital scales and execution risk, your project report must reflect a realistic, feasible approach; most MSME-scale entrants should focus on pack assembly or component/tier supply rather than cell production. Sharda Associates has prepared over 45,500 CA-certified project reports for MSME and manufacturing loan applicants across India. A lithium-ion battery manufacturing project report, built around your specific, realistic scope, starts at ₹2,999 and is delivered within 24-48 hours in the format accepted by SBI, PNB, Bank of Baroda, and other scheduled banks.

Machinery & Equipment | Cell testing/grading, pack assembly line, BMS integration/testing |
Raw Materials | Lithium-ion cells, BMS components, casing |
Certification | BIS CRS, AIS-156 (for EV applications) |
Working Capital | Labour, ongoing cell/component procurement |
A small pack assembly unit is realistically achievable around ₹5-15 crore; cell manufacturing starts at ₹50 crore and scales dramatically higher for genuine gigawatt capacity, a scale beyond most MSME entrants’ realistic reach.
Risks & Challenges
Cell supply dependence on imports (mostly from China) poses a genuine, continuing supply chain risk for pack assemblers, influencing both cost and lead time. Customer qualification trials for large OEM agreements can take 6-12 months, implying a longer road to income than the factory setup may indicate. Battery safety is truly non-negotiable—thermal or electrical failures in badly constructed or tested packs have serious safety ramifications, thus stringent BMS integration and testing should be intrinsic to your quality process rather than optional.
Frequently Asked Questions
It is a CA-certified document that explains your battery business plan, covering whether you will assemble packs or make cells, machinery, testing, certifications, investment, working capital and financial projections. Banks use it to judge whether your scope and costs are realistic.
Pack assembly buys ready-made lithium-ion cells and builds them into finished packs with a battery management system, casing and connectors. Cell manufacturing makes the cells themselves from chemical inputs, which needs far larger capital and technology. Most MSME-scale projects are realistic only for pack assembly.
Cells are procured, tested and graded for capacity and resistance, then arranged in series and parallel to reach the target voltage and capacity. A battery management system is integrated, the pack is fitted into its casing with connectors, and it is tested for safety and performance before dispatch.
Investment depends on pack type, capacity, cell testing and assembly equipment, BMS testing setup, safety infrastructure, certification costs and working capital for cells. Pack assembly needs much less capital than cell manufacturing. A project report calculates the exact cost for your chosen scope and capacity.
Battery products generally need BIS certification under the Compulsory Registration Scheme, and EV battery applications also need AIS-156 compliance. You will also need Udyam, GST, a factory licence, and fire safety and pollution control approvals. Standards change, so confirm current requirements before launch.
Yes, MSME manufacturing units can apply for term and working capital loans, and may look at collateral-free options under CGTMSE where eligible. Approval depends on project cost, promoter contribution, repayment capacity and the bank’s appraisal. A realistic scope and certification plan strengthen the application.
Most cells used by Indian pack assemblers are imported, largely from China, because domestic cell production is still limited. Cell supply affects your cost and lead time, so your report should include a sourcing plan, price sensitivity and a buffer for supply delays.
Large OEMs usually run customer-specific qualification trials before placing orders, and these can take several months. Your revenue projections and working capital should account for this delay rather than assuming sales begin as soon as the unit is ready.
