With the need for more green options and need for renewable energy sources it becomes essential to have reliable energy storage to back up alternating solar and wind energy to ensure that everything runs smoothly. Researchers have put in all their efforts and come up with the most excellent battery for large scale energy storage. Despite the fact that Li-ion batteries are just ideal for cars and various tech gadgets when you talk about energy source on a larger scale they are not highly expensive and are neither environment friendly.
Several Researches have been conducted and most of the research scientists are of the thought that Sodium Ion Batteries are a solution to it for the reason that sodium is eco friendly and comparatively cheap. They have found out that Sodium Ion Batteries are just apt for storing large amount of renewable energy in one go.
The only drawback to using these advanced batteries is that there is a very short life because f the swelling of the anode after every charge and the sodium ions discharge so this results the battery to fall apart merely after 20 charge cycles. Thus an alternative solution to this problem was developed by Researchers at the University of Maryland with the use of paper thin layer of wood fibers that were coated with conductive carbon nano tubes and the base to this is the Sodium Ion Nano Battery. The reason why wood fiber is being used is because it has the capacity to withstand the swelling and will contract the anodes allowing the battery to last for more than four hundred charge cycles and thus making it one of the longest largest future energy storage nanobatteries.
One of the Assistant Professors in Materials Science said that the Inspiration to this idea has come from the trees. Wood Fibers are just perfect for storing liquid electrolytes thus making them not just the base of the battery but an active part of the battery. It was observed while testing that after the charging cycles the wood was wrinkled but yet remained intact. It was later revealed that the wrinkles helped in reducing the stress in the battery while discharging and charging which created a long lasting and flexible battery.
