Bloomin' batteries.

US/CANADA An influx of harmful algal blooms in Lake Erie that affected the water systems of Toledo, Ohio residents in 2014 has led to a new way of making sodium-ion batteries.

Scientists from Wayne State and Pennsylvania State Universities collected algae samples from the Lake Erie blooms converting them to hard carbon through a freeze drying and baking process. The resulting matter is a low-cost form of electrodes in sodium-ion batteries.

The study is appropriately named "Trash to Treasure." The electrodes made from the algal blooms holds more energy than sodium-ion batteries. The researchers hope their method helps sodium-ion batteries replace the more costly lithium-ion that is commonly used to power electronics. Read more about the study at
