How are batteries recycled? (2024)

FAQs

How are batteries recycled? ›

These can be regular lead–acid, sealed lead–acid, gel type, or absorbent glass mat batteries. These are recycled by grinding them, neutralizing the acid, and separating the polymers from the lead. The recovered materials are used in a variety of applications, including new batteries.

Yes, batteries definitely get recycled. Recycling batteries is possible because of a process called “hydrometallurgical extraction.” This process extracts metals, such as lithium, cobalt and lead, from the cells of used batteries. The extracted metals are recovered and reused in the production of new batteries.

The contents of the batteries are exposed using a shredder or a high-speed hammer depending on battery size. The contents are then submerged in caustic (basic not acidic) water. This caustic solution neutralizes the electrolytes, and ferrous and non-ferrous metals are recovered.

The low recycling rate for lithium and lithium-ion batteries comes down to a few significant challenges: Complex process. The process is sensitive and difficult because lithium is highly reactive and must be carefully handled. Cost.

Although innovations are happening quickly in lithium-ion battery recycling, currently there are two main methods to recover the metals out of black mass: A heat-based smelting process (pyrometallurgy). A liquid-based leaching process (hydrometallurgy).

To be recycled, EV batteries must first be dismantled, which is no simple task because batteries are not standardized. The packs from a Tesla, BMW, and Nissan EV are different sizes, containing differently-shaped battery cells joined together by welds and other connections that must be broken down.

Other potentially valuable and recoverable materials are graphite and manganese. Recycling processes today recover approximately 25% to 96% of the materials of a lithium-ion battery cell.

“Batteries are often described as resource-intensive. With a 95% proven recycling rate and a 10yr life, over 50% of battery minerals mined today will still be in use in 130 years. Add 5% performance improvement per cycle, and they will be delivering services forever.

Most unrecycled batteries end up sent to a landfill like most trash. Here are some negative impacts of throwing batteries away instead of recycling them: Toxic materials in batteries can enter water sources and cause pollution. Accidental or improper incineration can release toxic fumes into the air.

Due to the high energy density of lithium batteries, handlers may choose to discharge them before shipping them for recycling. EPA recommends that handlers ensure that any discharge is done with all appropriate safety measures in place to prevent fires and protect the health of workers and communities.

Are AA batteries actually recycled? ›

Some reclamation companies recycle these batteries; check with your local or state solid waste authority for management options. In most communities, alkaline and zinc carbon batteries can be safely put in your household trash.

This also means that the second-life battery market can expand into industries other than automotive. These processes also have downsides, such as anode materials not being recovered in hydrometallurgy, and extensive gas clean-up being required to avoid toxic air emissions in pyrometallurgy.

Every tonne of mined lithium results in 15 tonnes of CO2 emissions in the environment. In addition, it is estimated that about 500,000 litres of water are needed to mine approximately 2.2 million litres per tonne of lithium. This substantially impacts the environment, leading to water scarcity in already arid regions.

None of our scrapped lithium-ion batteries go to landfilling, and 100% are recycled. Lithium-ion battery packs should only be handled by qualified professionals at specifically designated facilities. The applicable rules and regulations for battery management vary by region and must always be followed.

"Lithium-ion batteries, including EV batteries, are recyclable. The metals inside an EV battery are incredibly valuable and infinitely recyclable.

Many of these components can be recycled. Glass composes most of the weight of a solar panel (about 75 percent), and glass recycling is already a well-established industry. Other materials that are easily recyclable include the aluminum frame, copper wire, and plastic junction box.

The lead battery industry has optimized the fact that lead in lead batteries can be infinitely recycled without any loss of quality or performance. At their end of life, lead batteries are separated into three key components – all of which are 100% recyclable – lead, plastic and acid.

The Benefits of Battery Recycling

Recycling car batteries is commonplace. And did you know that 99% of the materials are able to be recovered and reused in new products? It's one of the most efficient processes in recycling, so long as the battery makes its way to a processor.

Across the battery recycling value chain, from collection to metal recovery, revenues are expected to grow to more than $95 billion a year by 2040 globally, predominantly driven by the price of the recovered metals, expected battery cell chemistry adoption, regionalization of supply chains, etcetera.

In many cases, batteries—especially in vehicles—are retired from their first use but can be repurposed for a secondary use, such as stationary storage. Batteries can also be recycled, but some recycling processes require energy-intensive or environmentally damaging inputs.
