Cell manufacturing compatibility will determine which next-generation battery technologies scale, writes Dr Hyungrak Kim (above), executive vice president of manufacturing, Anthro Energy.
Made once or made millions?
For much of the past decade, the battery industry has focused on a familiar question: which battery technology will deliver the next breakthrough?
Researchers, startups and established manufacturers have introduced a steady stream of innovations promising higher energy density, faster charging, longer cycle life and improved safety. Silicon-rich anodes, advanced electrolytes, solid-state architectures and novel materials platforms have generated tremendous excitement across electric vehicles, defence systems, robotics and consumer electronics. But as the industry moves from research to commercialisation, a different question is emerging: Can these technologies actually be manufactured at scale?
Meanwhile, consultancy McKinsey, in its recent Battery 2035: Building New Advantages report, argues that future competitiveness will depend not simply on adding production capacity, but on overcoming manufacturing bottlenecks, improving yields and increasing operational efficiency. The industry has focused heavily on discovering new chemistries, but less on evaluating whether those innovations can be deployed efficiently through real-world manufacturing systems. As a result, many promising technologies spend years moving from the lab to commercial production, if they reach commercialisation at all. The next phase of battery innovation will not be defined solely by chemistry; it will be defined by commercialisation.
Scale is part of innovation
Battery innovation is often judged by performance metrics achieved in laboratory environments. Energy density, cycle life, charging speed and safety data frequently dominate industry discussions and investment decisions.
These metrics are nonetheless essential, but they tell only part of the story. A battery that performs exceptionally well in a laboratory cell may still face significant obstacles during commercialisation. Manufacturing introduces a different set of requirements altogether. Materials must be produced consistently, processes must be repeatable, equipment must operate reliably at industrial throughput, supply chains must support growing demand, and quality systems must function at scale.
In many cases, the challenge is not proving that a technology works. The challenge is proving that it can be manufactured millions of times with the same result. This is where some of the most promising technologies encounter their greatest hurdles.
Moving from gram-scale materials production to continuous industrial manufacturing is not simply a larger version of laboratory work. It requires a fundamentally different approach to engineering, operations and quality management. Organisations that incorporate manufacturing expertise early in product development often gain a significant advantage by identifying commercialisation risks before they become barriers to market adoption.
The value of manufacturing compatibility
The battery industry has invested hundreds of billions of dollars in manufacturing infrastructure. Gigafactories, material processing facilities, quality systems, supply chains and highly trained workforces have been built around decades of lithium-ion production experience. This raises an important question for emerging battery technologies: Should commercialisation require replacing that infrastructure or leveraging it?
The assumption that entirely new manufacturing ecosystems must accompany every next-generation battery technology may prove increasingly difficult to justify. Manufacturing compatibility should not be viewed as a constraint on innovation. It should be viewed as a force multiplier. Those technologies that can integrate into existing production environments often have a significant advantage because they reduce deployment risk, shorten qualification timelines, and accelerate adoption from the customer.
As industries from automotive to defence seek solutions that can be deployed within years rather than decades, compatibility may become one of the most important, yet under-appreciated, characteristics of successful battery technologies.
Commercialisation becomes strategic
A decade ago, battery manufacturing decisions were driven primarily by cost and efficiency. Today, resilience and strategic capacity have become equally important considerations. Governments, manufacturers, and end users increasingly recognise batteries as foundational technologies supporting energy storage systems (ESS), data centres, transportation, robotics, advanced electronics, defence systems and emerging AI-enabled devices.
In this environment, the ability to manufacture domestically, diversify supply chains and scale production reliably has become a competitive advantage in its own right. The battery industry is no longer simply building products. It is building critical infrastructure for commercialisation.
What defines tomorrow’s battery leaders?
The next generation of battery leaders may not be the organisations with the most ambitious laboratory results. They will be the companies that successfully bridge the gap between invention and industrialisation. That requires asking three questions of every new technology:
- Does it outperform existing solutions?
- Can it be manufactured using available infrastructure?
- Can it be produced reliably, economically, and at industrial scale?
The first question drives innovation; the second and third determine whether innovation reaches the market. For the battery industry, that particular distinction is becoming one of increasing importance.
Innovation remains the foundation of progress. But innovation alone does not build industries nor batteries. Industries are built through manufacturing, enabled by the ability to produce advanced technologies reliably, economically and at scale. The companies that scale to commercialisation will shape not only the future of batteries, but the future of the industries powered by them.
