Batteries made from seafood waste are just as good as lithium

In a paper published by the scientific journal Matter, some problems with traditional lithium-ion batteries are noted, but first we need to explain the basic structure of a typical battery. In its simplest form, a battery consists of an anode, a cathode and an electrolyte layer connecting the two. This is Chemistry 101. When a battery supplies or discharges current, an oxidation reaction takes place: charged ions are released from the negative terminal of the battery (the anode). These ions flow through the electrolyte to the cathode (positive terminal). Unfortunately, this electrolyte is usually not biodegradable.

“Huge amounts of batteries are produced and consumed, increasing the potential for environmental problems,” said Liangbing Hu, lead author of the Center for Materials Innovation at the University of Maryland. “For example, polypropylene and polycarbonate separators, which are commonly used in lithium-ion batteries, take hundreds or thousands of years to break down and harm the environment.”
