Cobalt Issues in Batteries

Cost and Supply Challenges

Cobalt is important for making batteries, but it causes problems. In 2024, the world had 288,200 metric tons of cobalt. This was a 21% increase from before. Most cobalt comes from the Democratic Republic of the Congo. The DRC makes about two-thirds of all cobalt. This means battery makers depend on one country. If the DRC has trouble, the supply can stop. The DRC has political problems and corruption. These issues can break supply chains. The DRC sometimes limits exports. This made cobalt prices go up a lot this year. Now, cobalt costs $24 for each pound. When prices change fast, batteries cost more. It is hard to know what batteries will cost. Cobalt is found with copper and nickel. If copper and nickel prices drop, miners dig less cobalt. This can cause shortages. The world market for cobalt may grow from $16.12 billion in 2024 to $34.73 billion by 2035. This is because more electric cars need batteries. When cobalt prices change, battery prices change too. This makes it hard for companies to keep battery costs steady.

Note: Battery makers keep facing problems with cobalt supply and price. This can make batteries cost more and be harder to get for people.

Ethical and Environmental Risks

Cobalt mining causes big problems for people and nature. In the DRC, many miners are women and children. They work in unsafe places. Some are forced to work or treated badly. Some even face modern slavery. Big mines also have dangerous jobs. Workers breathe in bad chemicals and dust. Cobalt from big and small mines gets mixed together. This makes it hard to know where it comes from.

Cobalt mining hurts the environment too. Studies show rivers and lakes near mines get very dirty. Water and soil get poisoned. This ruins crops and makes people sick. People living near mines get skin diseases and other health problems. They lose money because their land and water are bad. Mining uses a lot of fossil fuels. This adds to global warming. Dust from mining makes the air dirty. People near mines have more birth problems.

Key impacts of cobalt mining:

• Water gets polluted and land is ruined
• Farmers grow less food
• Miners and people nearby get sick
• Mining makes global warming worse

These problems show we need safer and better battery materials.

Cobalt-Free Lithium-Ion Battery Chemistry

New Cathode Materials

Scientists made new cathode materials for cobalt-free lithium-ion batteries. These materials help lower costs and are better for the environment. They use iron, manganese, and nickel instead of cobalt. The scientists build layers and add special elements to make batteries work better. These changes make batteries safer and easier to recycle.

The table below lists some studies and what they found about cobalt-free cathode materials:

Taking cobalt out of the cathode gives many good results:

• Battery production makes 15-30% less carbon pollution.
• Water use in making batteries drops by 30-45%.
• Less land and animal homes get disturbed, up to 40% less.
• Risks to people and nature from toxins go down a lot.
• Using iron and manganese means less worry about running out of materials, by 50-70%.
• Recycling these new materials could happen more often.

These changes make cobalt-free batteries better for people and the earth.

Energy Density and Cycle Life

Cobalt-free lithium-ion batteries use new cathode designs to store more energy. Old lithium iron phosphate batteries stored about 120 Wh/kg. Now, new designs can store up to 230 Wh/kg. Nickel manganese cobalt batteries still hold more energy, but cobalt-free batteries are catching up. These new batteries now power electric cars and energy storage systems.

Tests show these batteries work well. In labs, they hold about 190 mAh/g at 0.1C. After 100 cycles at C/3, they keep 88% of their power. In real-world tests, a 0.5 Ah cobalt-free battery pouch cell kept 72% of its power after 200 cycles. Scientists use neutron diffraction and Mossbauer spectroscopy to check battery life and safety.

• The cobalt-free cathode was tested in a 0.5 Ah battery pouch cell.
• The battery kept 72% of its power after 200 cycles.

These results show cobalt-free lithium-ion batteries last longer and work well. High-energy batteries with these new materials help electric cars and store renewable energy. The new chemistry helps batteries last longer and stay safe.

Performance & Cost Comparison

Charging Rates and Safety

Cobalt-free lithium-ion batteries now charge as fast as old batteries. Sometimes, they even charge faster. Many new batteries use special cathode materials. These materials help batteries charge and discharge quickly. For example, batteries with a TAQ cathode charge faster than old cobalt batteries. They also keep good conductivity and storage. This means users still get strong performance.

• Some cobalt-free batteries charge in under 15 minutes.
• They are as safe or safer than cobalt batteries.
• Stable materials lower the chance of overheating or fire.

The table below shows how LNMO, a top cobalt-free battery, compares:

These changes help drivers and device users trust their batteries. Fast charging and long life are now possible. The stable chemistry also keeps people safe.

Cost vs. Traditional Batteries

Cobalt-free batteries cost less than old batteries. Taking out cobalt, the priciest part, saves a lot of money. Cobalt costs about $28,500 per ton. This is much more than nickel, manganese, or aluminum. Makers use iron and other cheap materials to save money. Using more nickel also gives more energy without costing more.

A study from The University of Texas at Austin found new cobalt-free batteries cut costs and sometimes work better. Market studies show these batteries skip high costs and problems with cobalt. They use other materials to keep good performance and lower supply risks.

The table below compares average price per kilowatt-hour for battery types:

• LFP batteries, which do not use cobalt, are usually cheaper.
• In China, LFP cell prices dropped below $60 per kWh in 2024.
• Makers avoid costly materials, so batteries cost less.

Some case studies show cobalt-free batteries may have a bit less range or efficiency. Still, the lower cost and better supply make them a good choice for many uses.

Note: Taking cobalt out of batteries helps lower costs, makes them safer, and keeps battery supply steady for the future.

The move to cobalt-free batteries is changing the battery world. Companies now have good reasons to use this new technology. Many electric cars use these batteries because they cost less and help the earth. More than 60% of people want products made with safe materials. Car makers care about this too. About 72% of car companies focus on getting materials the right way.

The electric car market keeps getting bigger. More companies pick cobalt-free batteries to follow new rules and save money. The industrial sector saw a 25% jump in using these batteries. This shows more people agree to use less cobalt, even if there are still some problems to fix.

Switching to cobalt-free batteries helps the environment a lot. These batteries use less water and energy to make. They also cause less pollution. This helps keep land and animals safe near mines. Many electric cars now use these batteries, which means less harm from mining.

Companies like Apple help mining towns by teaching new skills. This helps people find other jobs. It also helps protect human rights in mining areas. Using cobalt-free batteries also answers worries about workers and nature.

Main benefits of cobalt-free batteries:

• Less pollution from mining
• Lower cost for electric car makers
• Safer jobs for miners
• Better supply for electric cars

The industry now works together to make batteries safer, cheaper, and better for the earth.

Cobalt-free lithium-ion batteries cost less and store more energy. The table shows that taking out cobalt and adding nickel helps batteries work better and cost less.
