Baked Leaf Batteries

This Sodium-Ion Battery Makes Use Of a Baked Oak Leaf

— February 23, 2016 — Tech
A group of scientists and researchers from the University of Maryland and the National Center for Nanoscience and Technology from Beijing have created a high-tech sodium-ion battery using a decidedly low-tech ingredient -- an oak leaf. The researchers baked the oak leaf before flushing it with sodium, creating a negative battery terminal.

The leaf's natural shape makes it ideal for battery use, thanks to its low surface area and the fact that it includes a lot of tightly packed miniature structures. The scientists baked a dry leaf at 1,000 degrees Centigrade for an hour, before immersing it in hydrogen chloride for six hours to get rid of inorganic impurities. The end result is a carbonized leaf whose pores can absorb sodium electrolyte.

This sodium-ion battery is a wonderful invention as it proves that organic materials do indeed have potential to take care of some energy needs.
Trend Themes
1. Organic Batteries - The use of organic materials in battery technology presents opportunities for sustainable and eco-friendly energy solutions.
2. Sodium-ion Batteries - The development of efficient and cost-effective sodium-ion batteries could revolutionize the energy storage industry.
3. Carbonized Leaf Batteries - The utilization of natural materials for battery electrodes could lead to advancements in battery technology and more versatile energy storage solutions.
Industry Implications
1. Renewable Energy - The renewable energy industry could benefit from the development of sustainable and eco-friendly batteries using organic materials.
2. Energy Storage - The energy storage industry could be disrupted by the introduction of more efficient and cost-effective sodium-ion batteries.
3. Battery Technology - The battery technology industry could see advancements in the utilization of natural materials for electrodes and the creation of more versatile energy storage solutions.
