8 New Ideas for Battery Technology in 2015

battery-300x2361Even though 2015 is only about halfway done, innovative new ideas for battery technology have been announced one after another this year.

Though these entries are still just ideas, they have the potential to change battery technology completely. Below are the eight best innovations to be announced within the last quarter:

1. Solar Cells Integrated with Lithium-Iodine Technology

Researchers at Ohio State University have used a solar cell to increase the efficiency of lithium-iodine technology. With the two battery technologies working together, it will reduce energy consumption by almost 20%.

2. Battery Parts Made from Plant Leaves

Lithium-ion batteries could soon be made out of silicon from reed leaves, according to scientists in Germany and China. This silicon is easy to process, making it a potentially cheap alternative to the less-effective carbon anodes.

3. Super Hot Lithium-Ion Batteries

South Korean scientists have developed a lithium-ion battery that can function even at temperatures of nearly 100°C.

4. Twice the Power

Samsung Electronics has doubled the capacity of their lithium-ion batteries by covering the silicon cathodes with graphene. However, this new idea may take a couple years before it arrives in the marketplace.

5. Mimicking Plants

Photosynthesis is the process plants use to turn sunlight into energy, and researchers at the University of California, Los Angeles used this process as an inspiration to design a solar cell that can store energy for weeks at a time.

6. Batteries made from Wood

Nanocellulose, tiny fibers made from wood, can be used to make batteries as demonstrated by the KTH Royal Institute of Technology in Sweden and Stanford University. Batteries made from nanocellulose can fit the surface area of a football field into one cubic decimeter.

7. Calcium: Not Just for Bones Anymore

Lithium-ion batteries may have a challenger, according to researchers in France and Spain. They are working on developing a battery made out of  calcium, a material that is much cheaper and less environmentally costly to obtain than lithium.

8. Skin Pigment

Dark skin is caused by the pigment melanin, and surprisingly, it is being tested to see if it is good at storing energy. River Road Research and the Rochester Institute of Technology received funding from the Department of Environmental Conservation to work on the project, and the early results are promising. Batteries using melanin would be cheaper to manufacture and less harmful to the environment.
