Innovation is the thorn in the side of the problem, they say, and no sector illustrates this more than the energy storage sector. Solid-State Batteries have come of age as the world pushes toward cleaner and more effective technologies.
These technologies, which have more energy, faster charging, and greater safety than standard lithium-ion batteries, are pushing the boundaries of energy storage. Startups leading the revolution have innovations in their own technologies that will double the global capacity of batteries.
Imagine EVs that travel twice as far on one charge, drones that can run for hours on end, and portable electronics that are smaller but stronger.
These possibilities aren’t just fantasies — they’re actually coming true with the help of five impressive startups. And that’s how they’re defining the future of energy storage.
1. Ampcera: Pioneering Solid-State Electrolytes for Ultra-Fast Charging

The Challenge:
Classic lithium-ion batteries containing liquid electrolytes have low energy density and pose major safety concerns (overheating, flammability)
The Solution:
The US startup Ampcera is tackling these issues by creating solid-state electrolytes (SSEs). These materials – such as sulfides, oxides with a garnet structure, and phosphates with a nasicon structure – offer excellent mechanical and thermal stability. Ampcera’s batteries offer lightning-fast charging and are suitable for EVs..
Why It Matters:
- Improved Safety: Solid electrolytes greatly decrease thermal runaway, a common problem in lithium-ion batteries.
- Better Performance over a Longer Period: With the startup’s technology, stable performance is maintained over a longer duration, eliminating the degradation issues that plague traditional batteries.
- EV Benefit: With super-fast charging speeds, Ampcera’s batteries could eliminate one of the main barriers to EV use — charging time.
2. GQenergy: Graphene Batteries for High-Capacity Applications

The Challenge:
Long charges and small capacities are major drawbacks of standard batteries, particularly when working at high-energy levels..
The Solution:
The Italian startup GQenergy uses graphene, a material with an excellent electrical conductivity, to make solid-state batteries. These batteries offer an impressive energy density of 252 Wh/kg, which allows faster charging and longer use.
Why It Matters:
- Robust: GQenergy’s graphene batteries are suitable for a variety of uses, from mobile devices to street lights.
- Innovation Through Design: The company has even created a Bluetooth-connected table lamp called QLisa, which illustrates how graphene batteries could be easily integrated into common everyday devices.
- Sustainable Production: Graphene-based batteries use fewer rare earth metals and are more environmentally sustainable.
3. Printed Energy: Flexible Batteries for Wearable Electronics

The Challenge:
Miniaturization of devices, including wearable electronics and IoT sensors, requires ultra-small and elastic energy storage.
The Solution:
Roll-to-roll printing created flexible, thin solid state batteries, developed by the Australian company Printed Energy. These batteries combine zinc, manganese oxides and polymers to produce lightweight yet efficient power storage devices
Why It Matters:
- Flexibility: They are printed in different forms and dimensions that allow for unique electronics and wearable designs.
- Cost Efficiency: Roll-to-roll printing lowers the manufacturing cost and opens new markets for advanced energy storage.
- Strictly Consciousness: By making the use of less toxic components, Printed Energy supports efforts around the world to reduce the environmental footprint of battery production.
4. PJP Eye: Carbon Batteries for Longer Lifespan

The Challenge:
While consumer devices have become more energy-efficient, battery technology has struggled to keep pace in terms of lifespan and sustainability.
The Solution:
Japanese startup PJP Eye has developed solid-state carbon batteries that use carbon for one or both electrodes. These batteries are lightweight, longer-lasting, and more sustainable than traditional lithium-based alternatives.
Why It Matters:
- High Energy Density: Carbon electrodes enhance storage capacity without compromising on weight or size.
- Structural Integration: PJP Eye’s technology supports structural batteries, which can be embedded into the chassis of devices for reduced weight and enhanced design freedom.
- Sustainability: Using carbon reduces dependency on materials like cobalt and lithium, whose extraction poses significant ethical and environmental concerns.
5. Intecells: Cold Plasma Tech for Efficient EV Batteries

The Challenge:
Range anxiety — anxiety about battery range — remains a major impediment to widespread EV use.
The Solution:
The US startup Intecells uses cold plasma to make light, energy-dense solid-state batteries. The recycling process removes the largest amount of waste, and only the raw materials directly involved in generating the battery capacity are recycled.
Why It Matters:
- Efficiency: Intecells’ processes lower the production cost, which may increase the price of EVs.
- Range Enhancement: Higher energy density means longer range per charge, solving one of the most common issues among EV enthusiasts.
- Sustainability: The startup’s waste-minimization strategy encourages a circular economy for battery manufacturing.
The Bigger Picture: Why Solid-State Batteries Matter
Solid state batteries can transform energy storage, taking on the shortcomings of existing lithium-ion technologies. They offer:
- Enhanced Energy Density: Provide longer battery life for devices and increased range for EVs.
- Higher Safety: Solid electrolytes reduce the risk of fire associated with liquids.
- Quicker Charging: Important for applications such as EVs, where delays are an impediment.
- Efficient Environment: Using carbon or graphene reduces the environmental impact of battery manufacturing.
Global Implications and Future Outlook

The innovations driven by these startups have far-reaching consequences:
- Electric Vehicles: With better capacity and security, solid-state batteries can help the world to move toward EVs at a faster pace, decreasing our fossil fuel usage.
- Solar/Wind Power Battery: High capacity batteries allow renewable energy to be stored safely, reducing solar/wind power intermittency.
- Handhelds: From smartphones to wearable devices, solid state batteries promises to create lighter, more powerful devices.
Driving the Future with Solid-State Innovation
Creating energy storage is no longer a choice, it’s a necessity. These five companies are not only helping advance solid-state batteries but also paving the way for a healthier, more efficient future. Their work is the ideal blend of technological ambition and environmental responsibility, and promises solutions that will transform industries across the world.
While the demand for energy savings across the globe is increasing, solid-state batteries are quickly becoming the linchpin of the clean energy future. Whether it’s the potential to extend the lifespan of EVs, to fuel future machines, or to power renewables, the possibilities are endless. The only question now is, how quickly will the world adopt these game-changing technologies? For such startups, the answer is obvious: the future begins today.
