Cobalt-Free Batteries
To achieve more sustainable energy solutions, researchers are working hard to develop cobalt-free battery technology. These batteries reduce reliance on the finite resource cobalt and improve the sustainability of energy storage and supply chains.
Cobalt-Free Batteries:
Researchers at MIT have designed a new lithium-ion battery with a cathode based on organic materials instead of cobalt or nickel.
Cobalt-free batteries aim to provide a more sustainable way to power electric cars, addressing concerns about the environmental impact of cobalt mining.
In 2024, researchers at MIT have made significant strides in developing a more sustainable approach to powering electric cars by creating a cobalt-free battery. Here are the key details:
- Cathode Based on Organic Materials:
- The new lithium-ion battery features a cathode made from organic materials instead of cobalt or nickel (which are commonly used in traditional lithium-ion batteries).
- Cobalt-free batteries address several critical issues associated with cobalt:
- Environmental Impact: Cobalt extraction poses risks to land, air, and water due to toxic waste generated around mining sites.
- Supply Constraints: Cobalt is scarce, and its price can fluctuate dramatically.
- Social Costs: Many cobalt deposits are located in politically unstable regions.
- The organic cathode material offers comparable storage capacity, charging speed, and electricity conduction rates as cobalt batteries.
- Moreover, it can be produced at a much lower cost, potentially revolutionizing the battery industry.
- Benefits of Cobalt-Free Batteries:
- Sustainability: By eliminating cobalt, these batteries reduce the environmental impact and reliance on scarce metals.
- Cost-Effectiveness: Lower production costs make them an attractive alternative.
- Performance: They match or exceed the performance of cobalt-containing batteries.
- Future Implications: As electric vehicles become more prevalent, cobalt-free batteries could play a crucial role in sustainable transportation.
This breakthrough represents a significant step toward cleaner, greener energy storage solutions for the future!

Solid-State Batteries
Solid-state batteries have higher energy density and greater safety because they use solid electrolytes rather than liquid or gel electrolytes. This technology promises faster charging times and longer service life, while reducing the risk of fire and explosion.
- Solid state batteries have gained significant attention. Unlike traditional lithium-ion batteries that use liquid electrolytes, solid state batteries employ a solid electrolyte.
- These batteries offer several advantages:
- Increased Range: Solid state batteries can provide more range for electric vehicles (EVs).
- Faster Charging: They allow quicker charging times.
- Longer Lifespan: Solid state batteries can be charged and discharged over 6,000 times, surpassing other pouch battery cells.
- Enhanced Safety: The solid electrolyte reduces the risk of leakage or thermal runaway.
- Sustainability: They offer better recycling opportunities.
- ProLogium, a startup in Taiwan, is already producing solid state batteries at scale. Their Taoke factory in Taoyuan is delivering these batteries to EV manufacturers this year. Plans are also underway for a second factory in France.
- The challenge lies in achieving economical production at scale, but ProLogium’s innovative manufacturing technologies have improved efficiency and reduced costs.
Research in New Materials
Research on new materials for lithium batteries aims to improve battery performance and stability. This may involve developing new anode and cathode materials, as well as improving electrolyte formulations to achieve higher energy density, longer cycle life and faster charging.
New Tech in EV and ESS
