Lithium-Air Batteries

Lithium-air batteries, also known as lithium-oxygen batteries, have been the subject of research and development for several decades, and they are just starting to make their first steps commercially in 2023.

Until now they were still in the experimental stage and not yet commercially available in large quantities. They are a type of rechargeable battery that holds the potential for high energy density, something that makes them invaluable for applications requiring electricity for long periods of time.

The exact date of their invention is difficult to pinpoint, as multiple researchers and organisations have contributed to their development. A large part of the research involves finding ways to improve the efficiency and stability of the technology, as well as finding stable electrolytes, preventing side reactions, and managing the formation and decomposition of lithium peroxide. Researchers and scientists are actively working to overcome these challenges to achieve the potential of lithium-air batteries as a high-energy-density storage solution.

Lithium-air batteries have the highest energy density among all known batteries. They can store 5-10 times more energy than lithium-ion batteries of the same weight and twice as much energy for the same volume. Researchers have made a small rechargeable lithium-air battery that has a high current density, which means it can deliver more power. This makes them great for electric vehicles because they are lightweight and efficient.

However, the biggest challenge with these batteries has been that they can only be charged and discharged about 50 times, whereas lithium-ion batteries have a significantly higher number of charge cycles. This limited number of cycles is a problem for electric vehicles that need batteries that can be recharged thousands of times. But for devices like hearing aids, lithium-air batteries are already being used as one-time-use batteries with great success.

Recent advancements in the production of Lithium-Air batteries may mean we are up to very interesting developments on the reign of Li-ion batteries in electric vehicles, as Lithium-Air is a technology that promises much greater autonomy and range for cars. Here’s a video on the subject:
