Top 3 Pure-Play Battery Stocks to Watch in 2025

What’s driving investment in battery stocks? Well, the global battery industry has surged since over a decade driven mainly by lithium-powered technology. EVs are no longer a futuristic idea—they are now mainstream.

Electric vehicles play a crucial role in reducing greenhouse gas (GHG) emissions. In 2021, plug-in EVs, including all-electric and plug-in hybrid models, prevented approximately 5.5 million metric tons of carbon dioxide (CO₂) emissions in the United States. This reduction is equivalent to removing over 1.1 million gasoline-powered cars from the road for a year.

What’s Fuelling Battery Stock Investment in 2025? 

With countries pushing for stricter emissions regulations and phasing out gasoline cars, advancements like this could accelerate the transition to electric transportation. Thus, innovations in battery technology will play an important role in making EVs more advanced, safe, and climate-friendly.

Solid-state batteries are emerging as a game-changer. They promise better performance for EVs, consumer electronics, and renewable grids.

Rising Demand for Battery Technology

Statista revealed data from Bloomberg that showed a rapid surge in demand for lithium-ion batteries in EVs and energy storage over the past decade. In 2010, the total demand was just 0.5 gigawatt-hours. By 2020, it had skyrocketed to around 526 gigawatt-hours.

• This growth is set to continue, with projections reaching an astonishing 9,300 gigawatt-hours by 2030.
• This increase means millions of new EVs, storage systems, and consumer devices worldwide.

However, analysts say that this industry is a high-risk, high-reward space. In this guide, we’ll explore the top pure play battery stocks to invest in 2025. Keep reading.

QuantumScape: Leading the Solid-State Revolution

QuantumScape (QS) is at the forefront of solid-state battery technology. Based in California, this company is pioneering lithium-metal solid-state batteries with a unique ceramic separator.

With backing from Volkswagen and Bill Gates, the company aims to overcome the limitations of traditional batteries by improving energy density, charging speed, and safety.

Key innovations include:

• Anodeless design – Eliminates the need for a conventional anode, reducing weight and increasing efficiency.
• Ceramic separator – Enhances safety and stability compared to liquid electrolytes.

The company’s first commercial product, QSE-5, is set for larger sample deliveries in 2025, keeping them on track for commercialization.

Sustainability Focus

Solid-state batteries could cut emissions in battery production by 40%, according to the European Federation for Transport and Environment (EFTE). QuantumScape’s anode-free design further reduces the environmental impact by eliminating lithium-metal foil manufacturing. By pioneering these technologies, the company is supporting the energy transition and a lower-carbon future.

QuantumScape ranks moderately well among high-growth battery stock investment opportunities. Stock experts reckon that while it offers strong potential, other stocks may deliver higher returns in a shorter period.

Solid Power: A Competitive Contender

Solid Power (SLDP) specializes in all-solid-state battery technology for electric vehicles. Unlike conventional lithium-ion batteries, Solid Power’s batteries use a sulfide solid electrolyte, making them safer, more stable at high temperatures, and potentially cheaper to produce.

Why Solid Power Stands Out

• Pioneering sulfide-based solid electrolytes – The company produces the most advanced solid electrolytes at pilot scale.
• Scalable production – Uses existing lithium-ion manufacturing infrastructure.
• High-profile partnerships – Collaborates with BMW, Ford, and SK On to advance battery production.

Financial Performance 

In 2024, Solid Power generated $20.1 million in revenue, up from $17.4 million in 2023. The growth is attributed to key partnerships and technology advancements. By 2028, the company expects to supply solid-state battery technology for 800,000 electric vehicles annually. This is a huge milestone in mitigating emissions.

Key goals for 2025 include:

• Advancing electrolyte innovation and scaling up production.
• Launching a pilot continuous electrolyte manufacturing line.
• Expanding customer collaborations and increasing sample deliveries.

Solid Power may present significant growth potential, but its financial stability remains a concern. Therefore, investors should weigh the risks before committing.

Ilika Technologies: A Niche Player with Unique Strengths

Ilika Technologies (LON: IKA) is a UK-based company focusing on solid-state batteries for specialized applications, including MedTech, Industrial IoT, and Consumer Electronics. Unlike other players targeting EV batteries, Ilika’s strategy focuses on smaller, high-value markets.

The company has two product lines, namely, Stereax cells and Goliath large format cells. The former is used primarily to power miniature medical devices and industrial IoT. The latter targets the automotive industry and cordless consumer appliances.

Environmental Commitment

The company prioritizes sustainability and has been assessing its annual carbon footprint since 2021. It has been implementing eco-friendly initiatives such as:

• Zero waste to landfill
• Renewable energy-powered facilities
• Encouraging green commuting options

Additionally, Ilika has received a Green Economy Classification and Mark from the London Stock Exchange, signifying its contribution to sustainable technologies.

Still a Speculative Stock

Ilika remains a speculative stock, currently trading as a penny stock with a market cap under $50 million. However, its early focus on non-automotive applications could provide an advantage if solid-state batteries become standard across industries.

While QuantumScape and Solid Power aim to revolutionize EV batteries, Ilika is carving a niche in specialized markets. With countries phasing out gas-powered cars, the battery market is set to grow. Thus, investing in battery stocks looks promising.

However, investors should consider each company’s financial stability, technology roadmap, and market positioning before making a decision.
