With electric vehicles (EVs) that get us places, cell phones that connect us to others, and utility-scale electric grid storage that powers our homes, batteries are all around us.
Batteries can be either mobile, like those in electric vehicles, or stationary, like those needed for utility-scale electricity grid storage.
As the nation transitions to a clean, renewables-powered electric grid, batteries will need to evolve to handle increased demand and provide improved performance in a sustainable way.
When was the first battery invented?
You''ve probably heard of lithium-ion (Li-ion) batteries, which currently power consumer electronics and EVs. But next-generation batteries—including flow batteries and solid-state—are proving to have additional benefits, such as improved performance (like lasting longer between each charge) and safety, as well as potential cost savings.
These next-generation batteries may also use different materials that purposely reduce or eliminate the use of critical materials, such as lithium, to achieve those gains.
The components of most (Li-ion or sodium-ion [Na-ion]) batteries you use regularly include:
Solid-state batteries use solid electrolyte solutions, which don''t need a different separator. That makes them safer because they are less prone to leakage from damage or swelling in hot temperatures.
Flow batteries, which are powered by reduction-oxidation (redox) reactions, involve two different liquid electrolytes that pass ions or protons back and forth through a porous membrane. These batteries can store larger amounts of energy—as much as the size of the electrolyte cells can contain—and don''t use flammable or polluting materials.
Innovations in battery technology over recent decades have unlocked a wide range of technologies for various uses, many of which we rely on in our daily lives, such as:
Since their invention, batteries have come to play a crucial role in enabling wider adoption of renewables and cleaner transportation,which greatly reduce carbon emissions and reliance on fossil fuels.
Think about it: Having a place to store energy on the electric grid can allow renewables—like solar—to produce and save energy when conditions are optimal, ensuring there''s round-the-clock reliable energy on those (literal) rainy days.
Next-generation batteries are also safer (less likely to combust, for example), try to avoid using critical materials that require imports, rare minerals, or digging into the earth, and can store more energy (letting you drive further in your electric vehicle before finding a charging station, for example).
The U.S. Department of Energy (DOE) and its Advanced Materials and Manufacturing Technologies Office (AMMTO) is helping the U.S. domestic manufacturing supply chain grow to fulfill the increased demand for next-generation batteries.
The first battery was invented by Italian physicist Alessandro Volta in 1800 and eponymously named the "Voltaic Pile". (The unit of electromotive force, "volt", also comes from Volta).
By moving innovations from the research and development (R&D) stage toward the market—and ultimately your pocket, garage, or facility, AMMTO helps technology progress to meet Americans'' needs. Advanced manufacturing facilities can help the United States improve the manufacturability and scalability of these essential technologies and move us closer to the goal of achieving a net-zero-emissions economy by 2050.
Through DOE and AMMTO support, members of the industry, academia, government, and entrepreneurial sectors are reducing costs and increasing the availability and performance of next-generation batteries to meet future demand.
Instead of starting from scratch every time, manufacturers can customize and expand upon standardized tools and methods—often referred to as platform manufacturing technologies—that are designed to be flexible and adaptable, saving manufacturers time and resources.
That can also reduce the time to market for next-generation energy storage materials and devices and bridge knowledge gaps between small-scale R&D and large-scale commercial manufacturing, leading to immediate impact, increasing the commercial domestic supply of battery storage devices.
With a more robust battery manufacturing industry, not only can we accelerate the transition to a clean energy economy, but we can also create good-paying jobs for Americans.
To bring these technologies closer to reality, we need:
In addition to supporting improved manufacturing of batteries, AMMTO supports efforts to improve the actual performance (such as reliability, safety, rechargeability, and amount of energy stored) as well as the environmental sustainability of production. These advances can make them less dangerous to consumers, easier and cheaper to produce, and better adapted for emerging renewable applications that may subject them to harsh conditions, such as high temperature (like EVs), high pressure (like airplanes), or smaller containers (like smart watches or pacemakers).
And we''re doing all this on home soil. As the United States works to improve energy independence and security, we need strong domestic manufacturing capabilities. That means adjusting processes and technologies within manufacturing facilities to keep up with new materials, battery designs, and growing needs.

The critical minerals and large capacity battery supply chain review initiated by Executive Order 14017 recommended (1) taking a mineral-by-mineral approach to both expand sustainable, environmentally-responsible domestic mining, processing, and recycling of critical minerals; (2) working with partners and allies to diversify international supply chains, recognizing that America''s national and economic security is bolstered through strong alliances, and international coalitions of reliable partners reinforce the security of our supply chains; and (3) developing a faster and fairer domestic process that meets strong environmental and labor standards, ensures meaningful community engagement and consultation with Tribal Nations, and reduces time and cost of permitting.
The Initiative will work through the Partnership for Global Infrastructure and Investment, and leverage ongoing work by the Department of State, to work with partners and allies to strengthen critical mineral supply chains globally, and it will leverage and maximize ongoing efforts throughout the U.S. government to meet resource requirements and bolster energy security.
We''ll be in touch with the latest information on how President Biden and his administration are working for the American people, as well as ways you can get involved and help our country build back better.
The United States battery industry has fallen dangerously behind the global leaders. The main thrust of the U.S. policy response to the battery crisis must be the urgent commercialization of next-generation technologies where the United States can actually enjoy a competitive advantage.
