Specialists have fabricated a progressively proficient, more reliable potassium-oxygen battery, a step toward a potential solution for energy storage on the country’s power grid & batteries with more life for cellphones & laptops.
According to a study released on Friday in the journal named ‘Batteries & Supercaps’, the Ohio State University-based researchers stated about their results around the construction of a battery’s cathode, which is responsible for the storage of the energy produced by the chemical reaction going on in a metal-air battery. The scientists state the results could help in the process of making renewable energy sources like wind & solar energy much more viable options for the power grid with the help of cheaper & more effective energy storage.
Since no renewable energy source releases carbon-dioxide, they don’t affect the issue of global warming negatively. But there is also a downside, which is they can only produce energy when there is sunlight or there is wind blowing. To harness the full potential of their energy to be considered reliable sources of energy, a method has to be fabricated where the excess energy gathered from the sunlight can be stored away as potential energy.
Many scientists & companies are trying to come up with storage solutions, which range from lithium-ion batteries, right up to huge batteries sized as big as a box store constructed using the metal vanadium.
Potassium-oxygen batteries were also thought of as viable options until they rapidly degraded with each charge, making them not viable for the purpose. There is ongoing research to find ways to make the system viable with potassium-oxygen batteries since they can be relatively cheap to produce.
A very important aspect of energy storage is that the batteries have to be made cheaply. Lithium-ion batteries can be expensive to manufacture, even though they are considered to be a viable option.
