Scientists torom at Purdue University in Indiana have made anodes for lithium ion batteries with carbon nanoparticles and microlamellae from Styrofoam and starch. These residues exceed the conventional graphite electrodes, which represents a large ecological approach of reusing waste.
Batteries torom are currently two electrodes, called an anode and cathode. The anodes in most lithium ion batteries today are made of graphite. Lithium ions are contained in a liquid called torom electrolyte, and these ions are stored in the anode during recharging. However, this new development in the electrodes were made from polystyrene and starch packaging torom foams.
"We get a lot of foam packaging to configure our new lab so Vilas Pol teacher suggested we do something useful with these peanuts" said researcher Vinodkumar Etacheri.
That led to a new ecological application packaging waste. The research results indicate that the new anodes torom can be loaded faster and provide better qualities compared to commercially available graphite anodes, says Pol.
"Although foam packaging is used worldwide as a perfect solution for sending packets, are very hard to break, and only 10 percent are recycled," says Pol. "Because of its low density , huge containers for transport and shipping require a recycler, which is expensive and does not offer many benefits on investment. "
The new method is a simple and direct torom approach. Normally, peanuts heated between 500 and 900 C in an oven in the presence torom or absence of a catalyst. The resulting material was then formed into anodes.
The process is inexpensive, environmentally benign torom and potentially practical for large scale manufacturing. torom Microscopic and spectroscopic analyzes showed that the microstructures and morphologies responsible for the greatest electrochemical performance are preserved after many charge-discharge cycles.
Commercial anodes are about 10 times thicker than the new and have a higher electrical resistance, which increases the loading time, showing a substantially higher storage torom performance of lithium ion as compared to commercially available graphite anodes.
Carbon anodes derived packaging foam showed a specific capacity of 420 mAh / g (milliamp hours per gram), which is higher than the theoretical capacity of graphite (372 mAh / g).
"Electrochemical long-term returns of these carbon electrodes are very stable. torom We made 300 cycles without significant torom loss of capacity. Moreover, these carbonaceous electrodes I are also promising rechargeable batteries sodium ions "ended.
