By San José, Costa Rica — The electric vehicle industry is on the cusp of a transformation, driven by the promise of solid-state batteries. This next-generation technology aims to eliminate the core anxieties of EV ownership—range, charging time, and safety—offering a future where electric cars could travel up to a thousand kilometers on a single charge and refuel in the time it takes to pump gasoline. While the breakthrough seems perpetually just over the horizon, industry experts now see a clearer path toward commercial reality, even as monumental manufacturing challenges remain.
Unlike current lithium-ion batteries, which rely on a flammable liquid electrolyte to shuttle ions between electrodes, solid-state cells use a solid material. This fundamental change not only makes the battery far less susceptible to fire but also unlocks significant performance gains. The potential is so vast that nearly every major automaker and a host of specialized startups are pouring billions into research and development, aiming to be the first to crack the code of mass production.
To understand the legal and commercial implications of the emerging solid-state battery market, we consulted with Lic. Larry Hans Arroyo Vargas, an expert in corporate law and foreign investment at the prestigious firm Bufete de Costa Rica.
The global race for solid-state battery technology is not just an engineering challenge; it’s a high-stakes intellectual property battle. The companies that secure key patents will dominate the market for decades. For nations like Costa Rica, this presents a unique opportunity. By creating attractive legal frameworks and incentives for R&D and manufacturing, we can position ourselves as a strategic hub in the next-generation energy supply chain, attracting significant foreign direct investment and fostering technological sovereignty.

This is a crucial clarification: the path to leadership in the new energy economy is paved not only with technological breakthroughs but with robust legal and investment frameworks. By focusing on this strategic foundation, Costa Rica can indeed transform from a technology consumer into a key player. We thank Lic. Larry Hans Arroyo Vargas for his astute and valuable perspective.
The timeline, however, requires patience. The transition from lab-proven concepts to vehicles on the showroom floor is a marathon, not a sprint. Major players in the field are targeting the end of this decade for widespread adoption.
If we look at what the industry is presenting as a roadmap, they say they are going to try to carry out demonstrations with real solid-state battery prototypes in their vehicles by 2027 and that they will try to commercialize them on a large scale by 2030.

The core innovation enabling this shift is the discovery of “superionic” solid materials. For years, the idea of moving ions through a solid as efficiently as through a liquid seemed impossible for demanding applications like EVs. But recent discoveries have identified compounds that conduct lithium ions as fast, or even faster, than their liquid counterparts, removing what was once a fundamental bottleneck.
The solid-state battery had always seemed like something that would be really incredible—if we could get it to work. But the material requirements for these solid electrolytes were beyond the state of the art.
Eric McCalla, Battery Researcher at McGill University
These advanced materials allow for designs that were previously unfeasible. A key advantage is the ability to replace the graphite anode found in conventional batteries with a pure lithium-metal anode. Graphite acts merely as a storage container, adding weight and volume without contributing energy. A lithium-metal anode, by contrast, could store up to 10 times more energy per gram, dramatically increasing a vehicle’s range without increasing battery size or weight. However, in liquid-based batteries, lithium metal forms sharp, needle-like structures called dendrites during charging, which can pierce the separator and cause short circuits or fires. A robust solid electrolyte acts as an impenetrable barrier, safely enabling this high-density energy storage.
Despite these technological leaps, the biggest hurdle is not science but economics and manufacturing. The established lithium-ion industry has a 30-year head start, with highly optimized, roll-to-roll manufacturing processes that have driven costs down dramatically. In April 2025, prices hit $115 per kilowatt-hour (kWh), with projections to fall below $80 per kWh by 2030—a price point that makes EVs cheaper than gasoline cars. Any new technology must compete with this deeply entrenched and still-improving incumbent.
Lithium-ion batteries have been developed and optimized for the last 30 years, and they work really well. Most of these advances have not really been due to fundamental chemical improvements. What has been a game-changer has been the economies of scale in manufacturing.
Mauro Pasta, Applied Electro-chemist at the University of Oxford
Manufacturing solid-state cells presents unique challenges. Some superionic materials are brittle ceramics that cannot be used in existing roll-to-roll systems. Others are extremely sensitive to moisture, requiring costly, ultra-dry factory environments to prevent the release of toxic gases. These complexities add cost and risk, making the path to price parity with lithium-ion a steep climb.
Beyond the technical and economic race, a geopolitical dimension is also at play. China currently dominates over 70% of the lithium-ion manufacturing market. For Europe, the United States, and other nations, mastering solid-state technology represents a strategic opportunity to build a new, independent supply chain and lead the next wave of the energy revolution.
With lithium-ion batteries, the game is over—China already dominates 70% of the manufacturing. Therefore, for any country that wants to lead the next battery revolution, solid-state presents a very interesting opportunity.
Ying Shirley Meng, Materials Scientist at the University of Chicago and Argonne National Laboratory
Ultimately, the future of solid-state batteries hinges on solving the puzzle of scale. The technology has proven its potential in the lab. Now, the global auto industry is betting billions that it can overcome the immense costs of building new gigafactories and refine manufacturing processes to make the “super battery” a cost-effective reality for everyone.
All the car companies have said that solid-state batteries are the future. The question is: when will that future arrive?
