From 1991 to 2024, lithium-ion battery cell prices have fallen by 99%

The widespread need for rechargeable batteries has fueled surging lithium demand

As of 2025, the average person uses 27 times more mined lithium than they did in the 1990s, with the US ranking second globally in consumption despite producing less than 1% of global supply. However, potential alternative materials and boom-and-bust cycles have challenged the profitability of mines and future demand for the mineral.

How lithium has become one of the world's most important elements

Lithium is the driving force behind electric vehicles as the key element in the lithium-ion batteries that power the cars. But as demand for EVs rises, will global lithium supply keep pace with demand? This report projects demand will reach up to four million metric tons of the mineral compound containing lithium by 2030, with batteries accounting for 95% of end-use applications.

As of 2022, only about 5% of lithium-ion batteries are recycled globally

Traditional recycling methods have been inadequate for lithium batteries, prompting manufacturers to explore more sustainable battery designs, alongside robotic disassembly and ultrasonic techniques to improve recycling rates. Studies have shown that mining for new lithium requires significantly more water and energy than recycling and results in declining vegetation near mines.

Lithium can store and deliver substantial energy for its cost and weight

When exploring which compounds would be best suited for batteries, scientists sought elements that were relatively inexpensive to mine, readily available, and that provided high energy density—how much chemical energy an element could store for its size. Lithium-ion batteries provide these benefits and discharge at very low rates when unused.

Legacy electronics have prevented significant advancements in alkaline batteries

While lithium-ion batteries have increased in energy density multiple times since their commercialization in 1991 and can be sized to various capacities by connecting numerous electrochemical cells, disposable alkaline batteries have been forced to maintain their 1.5-volt standard and form factors for compatibility with existing devices.

Lithium-ion batteries are the standard for rechargeable devices

The costly setup of new mining operations and challenges with recycling amid growing demand have led researchers to search for alternatives, including sodium-ion, solid-state, and lithium-sulphur batteries, despite challenges with scalability.

The 2019 Nobel Prize in Chemistry was awarded for lithium-ion battery development

Stanley Whittingham developed the first functional lithium battery in the early 1970s, while John Goodenough doubled its electrical potential in 1980 by replacing the cathode, thereby enhancing its commercial viability. Five years later, Akira Yoshino developed an anode using carbon material, reducing the risk of flammability.

View the five most expensive metals used to make batteries

Before 2021, when lithium carbonate became the most expensive metal for use in electric vehicle cathodes, cobalt was the most costly battery metal. Of the top five, copper is the only metal not used in cathodes, arguably the most important part of the battery, which determines performance, longevity, and range.

The first lithium-ion battery was invented at ExxonMobil

Initially a side project that became a priority due to the 1973 oil crisis, the battery's flammability risks and manufacturing challenges, along with the waning crisis, led the company to shut down its battery program. Other researchers would gradually improve upon published prototype designs in the next decade.

The lithium cathode includes nickel to increase energy storage per unit volume, as well as cobalt and manganese as stabilizing agents. Anodes are composed entirely of graphite, with aluminum and copper composing the current collectors for the cathode and anode, respectively. The battery is enclosed in a steel casing.

During manufacturing, lithium-ion and alkaline batteries are tested for short-circuiting

Lithium-ion batteries are made by manufacturing anodes, cathodes, and electrolytes via chemical processes, assembling these components into cells, and enclosing multiple interconnected cells within a protective casing. Disposable alkaline battery production involves filling steel containers with preforms—rings of powdered cathode material—paper-based separators, electrolyte solution, and an anode gel.

Chile, Argentina, and Bolivia hold more than 75% of the world’s supply of lithium

Despite the dependence of phones, laptops, electric cars, and other technologies on the soft, silvery-white metal for their batteries, residents of the Lithium Triangle have not seen the benefits of investments into mining this critical mineral, and have instead faced water shortages and pollution.

The abundance of raw materials may lead to sodium replacing lithium in batteries

Lower risks of thermal runaway, which can lead to fires and explosions, and less energy capacity loss at low temperatures support the shift. However, sodium's greater weight and lower energy density compared to lithium have made it best suited for stationary storage applications. (Some readers may experience a paywall.)

As of 2025, most EV batteries retain 95% or more of their range after three years

Data from over 30,000 electric vehicles shows that their batteries are lasting much longer than initially projected, which researchers suggest is due to improved battery management systems and real-world use often being less rigorous than high-performance testing. Cars with 150,000 miles or more that have not had a battery replacement retain at least 83% of their original range.

Sony set the standard for cylinder-shaped batteries when it repurposed manufacturing equipment used to make rolls of magnetic recording tape.

BYD overcame Tesla via state backing, cheaper cars, and vertical integration

Growing EV adoption requires battery management infrastructure

Despite rechargeable batteries' limited life cycle, companies like Spiers New Technologies have developed methods to repair, refurbish, repurpose and recycle these components to minimize environmental waste, lower demand for new critical minerals, and increase electric vehicle lifetimes.

Watch how metals are extracted from rechargeable devices during recycling

Recyclable batteries found in cars, phones, power tools, and other electronics contain lithium, cobalt, nickel, and other precious metals, whose reuse generates 70% fewer emissions than during their initial mining. Upon shredding these devices, a filter press squeezes the pieces through a proprietary fluid, which separates them for future reuse.

Thermal runaway reactions can cause batteries to catch fire or explode

If a lithium-ion battery is heated, punctured, crushed, or short-circuits due to manufacturing flaws or degradation, the cathode and anode can make contact without the resistance provided by a circuit. The ensuing spike in chemical reactions increases the temperature and can release oxygen, initiating and intensifying burning of the battery's interior.

Clean energy technologies are more mineral-intensive than burning fossil fuels

Solar panels use silver due to its high conductivity, hydropower plants use chromium in their steel alloys, and geothermal plants need titanium to withstand abundant heat and pressure. Lithium—used in energy storage—is expected to see over 500% increased demand from 2020 to 2025.

From 1990 to 2020, wind turbine height and blade length have more than tripled

Wind turbines' energy generation capacity—or maximum power rating—also increased by 375% from 1998 to 2023. As of that year, wind turbines can produce more energy per dollar than solar panels, though transportation and installation challenges remain.

Unless prices of fossil fuels rise significantly, their production is expected to slow

US oil and natural gas production skyrocketed from 2000 to 2020, largely due to advances in fracking. However, weak global energy prices have prevented this boom from translating into increased profits for fossil fuel companies.

Explore options for recycling batteries

Improper battery disposal can lead to fires and the leaching of harmful chemicals and toxic materials into local soil and water systems. Although many batteries contain metals that can be recycled with less energy than it takes to produce them, variability in regulations across municipalities and states can complicate efforts. (Some readers may experience a paywall.)

Solid-state batteries substitute the fluid electrolyte layer with a solid

The non-flammable solid greatly reduces the risk of fire and explosion, as well as the release of toxic gases via leaks in the existing sulfide-based systems. These batteries use garnet-type solid electrolytes, which provide high ionic conductivity and chemical stability but require temperatures above 1,000 degrees Celsius (1,800 degrees Fahrenheit) for fabrication.

Among renewable sources, geothermal rivals hydropower in lifetime cost

As of 2024, the levelized cost of energy—the average cost per unit of energy over the lifetime of a power plant—for geothermal power is surpassed only by solar photovoltaic and onshore wind. Geothermal's LCOE has remained relatively unchanged since 2007, with significant decreases held back by significant upfront installation costs.

Gradual chemical build-up reduces the effectiveness of rechargeable batteries

During charge cycles, small chemical deposits gradually form a film on the electrodes where they make contact with the electrolyte, trapping ions that would otherwise facilitate the flow of electricity. Mechanical degradation from electrode wear and electrical shorting from structural instability can also reduce battery capacity.

Tesla plans to eliminate the use of rare earth elements in future vehicles

At a 2023 Investor Day event, Elon Musk outlined steps to focus Tesla's efforts on climate action rather than new vehicle models. Musk estimates the transition to carbon-free, sustainable energy will cost $10T.

More batteries in the power grid would create an on-demand energy reservoir

Most power grids are inefficient because they require enough generation capacity at all times to avoid blackouts. This means at any given time, as much as 50% of generating capacity at power plants can go unused. Batteries would reduce this inefficiency and allow for real-time adjustments.

As of January 2025, Tesla is the second best-selling EV company in the world

Chinese automaker BYD saw nearly three times as many registrations of electric vehicles as Tesla through the sales of its plug-in hybrid and battery electric vehicles. Fellow Chinese competitor Geely sold 12.7% of all BEVs worldwide, surpassing Tesla's 12.4% share during the same period.

See how SpaceX has impacted costs throughout spaceflight history.

Electric vehicles have been around since the 19th century

The first EVs ran on rechargeable lead-acid batteries, which could travel 60 to 80 miles on a single charge. Women preferred these vehicles, which were quieter, less smelly, and did not require turning a hand crank to start the engine.

Batteries range in size based on their purpose, cost, and manufacturability

Lead-acid batteries used in combustion vehicles are resilient to temperature extremes, low-cost, and provide high surge current, which is needed for initial ignition. Alkaline batteries, including AA, AAA, and B, have long shelf lives and supply the low, steady power required for electronics with minimal demand fluctuations.

Electricity is produced when the ends of a battery are connected by a conducting wire, triggering chemical reactions that release the energy stored in chemical bonds.

Batteries are likely to stop working sooner in cold temperatures

The electrolyte separating the cathode and anode of a battery can thicken, impeding ion flow. Lower temperatures also slow the rate of chemical reactions, further reducing battery capacity. Large draws of power, such as when using heaters, heated seats, etc., in a car during winter, exacerbate battery drain further.

Pollution from lead battery recycling has led to widespread contamination

Many small-scale operations worldwide remain unregulated, bypassing environmental regulations and causing increasing health threats, primarily to children. A 2020 report by UNICEF found that one-third of the world's children are being poisoned by lead from recycled batteries, among other sources.
