Challenges in the Market

• High Development and Procurement Costs
  Developing advanced battery and power systems involves significant capital expenditure in Taiwan. The cost of high-energy materials, testing, and safety validation remains substantial. Budget constraints often limit large-scale procurement and deployment across multiple divisions. SMEs in the defense supply chain face additional barriers due to expensive certification processes. Although long-term operational savings are promising, high initial costs slow early adoption. Achieving cost reduction through economies of scale is essential for market maturity.

• Supply Chain Vulnerabilities
  Dependence on imported raw materials such as lithium, nickel, and cobalt exposes Taiwan to geopolitical risks. Supply disruptions can delay manufacturing and maintenance of defense energy systems. Governments are working to establish domestic processing and recycling capabilities. However, the transition to self-reliant supply chains requires time and significant investment. Until localization efforts succeed, supply volatility will remain a persistent threat. Building strategic reserves and diversified sourcing strategies are critical mitigation measures.

• Thermal Management and Safety Concerns
  Battery systems used in military environments face extreme temperature variations and mechanical stress. Inadequate thermal control can lead to overheating, reduced lifespan, or safety hazards. Designing ruggedized thermal management systems increases complexity and cost. Failures in temperature regulation during missions can compromise system reliability. Continuous R&D in cooling technologies and battery design is essential to mitigate these risks. Safety concerns remain a top barrier for broader adoption in high-risk defense operations.

• Integration with Legacy Defense Systems
  Integrating modern power systems with older military equipment poses compatibility challenges. Legacy vehicles and platforms often require costly retrofitting to accommodate new energy systems. Software and hardware integration issues can delay deployment timelines. Custom engineering solutions increase costs and limit scalability. The transition to fully digital and electric systems therefore progresses gradually. Establishing standardized architectures can simplify future integrations.

• Environmental and Disposal Regulations
  Strict environmental regulations in Taiwan regarding battery disposal and recycling are creating compliance challenges. Hazardous waste management for lithium-based batteries demands specialized infrastructure. Non-compliance can result in penalties and operational restrictions. Developing sustainable recycling methods is necessary to minimize environmental impact. Governments are mandating lifecycle management policies to ensure responsible disposal.
