Southeast Asia Lithium-ion Battery Market Size and Share - Growth Analysis Report and Forecast Trends (2026-2035)

The Southeast Asia Lithium-ion Battery Market attained a value of USD 8.50 Billion in 2025 and is projected to expand at a CAGR of around 15.0% through 2035. With accelerating electric vehicle adoption driven by government EV mandates across Thailand, Indonesia, and Vietnam, surging investment in EV battery manufacturing by BYD, CATL, EVE Energy, and LG Energy Solution establishing ASEAN gigafactories, rapidly expanding data centre infrastructure across Singapore, Malaysia, and Thailand driving demand for lithium-ion UPS and energy storage solutions, and growing renewable energy integration creating grid-scale storage procurement, the market is set to achieve USD 22.90 Billion by 2035.

Key Market Trends and Insights

• Thailand dominated the Southeast Asia Lithium-ion Battery Market in 2025, driven by the country's established automotive manufacturing base - producing over 2 million vehicles annually - BYD's major EV factory investment, and the government's 30SC30 policy targeting 30% of vehicle production to be electric by 2030, creating structural demand for both EV traction batteries and battery cell manufacturing capacity.
• By Application, the Automotive segment holds the largest market share at approximately 55% in 2025 and is projected to maintain dominance through 2035, driven by EV adoption across Thailand, Indonesia, and Vietnam where Chinese EV manufacturers including BYD, SAIC-MG, and Great Wall Motors are building substantial production capacity and consumer market presence.
• By Battery Chemistry/Type, the LFP (Lithium Iron Phosphate) segment is expected to register the fastest CAGR over the 2026-2035 forecast period, reflecting the chemistry's thermal stability advantage in Southeast Asia's tropical climate, cost-competitiveness supporting entry-level EV affordability, and CATL's and BYD's large-scale LFP production capacity that dominates regional EV supply chains through ASEAN manufacturing investments.

Market Size and Forecast

• Market Size in 2025: USD 8.50 Billion
• Projected Market Size in 2035: USD 22.90 Billion
• CAGR from 2026-2035: 15.0%
• Fastest-Growing Regional Market: Indonesia (EV manufacturing)

The Southeast Asia Lithium-ion Battery Market encompasses automotive traction batteries, stationary energy storage systems, consumer electronics batteries, and industrial backup power solutions using lithium-ion electrochemistry across ASEAN nations. The region is experiencing a structural transformation as Chinese EV manufacturers establish manufacturing hubs - particularly in Thailand and Indonesia - that are creating ASEAN's first large-scale EV production ecosystem. Thailand's government has committed USD 1.5 billion in EV incentives targeting 30% of vehicle production to be electric by 2030, attracting over USD 3 billion in EV manufacturing investment from BYD, NETA, and Great Wall Motors. Indonesia - home to the world's largest nickel reserves - is positioning itself as the global centre of NMC battery supply chain integration, leveraging nickel supply advantages to attract battery cell manufacturing from CATL, LG Energy Solution, and Korean battery companies. Singapore's expanding data centre infrastructure and Malaysia's rapidly growing renewable energy sector create complementary demand vectors for lithium-ion energy storage systems, broadening the addressable market beyond automotive applications.

The Southeast Asia lithium-ion battery market growth is being reinforced by LFP chemistry's emergence as the dominant format for ASEAN EV applications. The International Energy Agency's 2025 EV Outlook confirms that LFP batteries captured more than 50% of electric car batteries in Southeast Asia in 2024, with LFP uptake led by BYD imports as the Chinese EV leader commands growing market share across Thailand, Malaysia, and Indonesia. EVE Energy's construction of a USD 422 million lithium-ion battery manufacturing facility in Malaysia's Kulim region - specifically targeting cylindrical cell production for electric two-wheelers - demonstrates the manufacturing investment wave transforming Southeast Asia from a battery import market toward a regional production hub. The region's data centre industry, with 352 facilities operational as of 2023 and rapid expansion continuing, is creating significant UPS and backup power battery demand that complements automotive sector growth.
