Silk Based Material To Make Rechargeable Li-Ion batteries Last Longer

With millions of gadgets today being powered by the Lithium-Ion batteries, be it your smartphone or tablet or even laptops, the research in the field of extending battery life has been on its peak. No only consumer electronics, the Li-Ion batteries have found major applications in electric cars, military gadgets and even the aerospace industry. The reason for their popularity is the above average battery life and compact size & shape. However, with increasing demand for these batteries to last longer on single recharge, researchers are working more dedicatedly than even to extend the battery life. One such research came to light in the journal ACS Nano, where a team claims to have developed a new green material derived from silk that can be used to create Li-ion batteries in a way that boosts their performance.

The team of researchers from Reseach Center of Materials Science, Beijing Institute of Technology have shown how the the hierarchical porous nitrogen-doped carbon (HPNC) nanosheets can be be prepared from simultaneous activation and graphitization of biomass-derived natural silk. These nanosheets exhibits features that show potential for storing electrochemical energy. By replacing graphite, the material most commonly used in batteries, with an alternative material that extends the energy capacity, the researchers were successful in improving the energy storage capacity.

The new 'green' material stores 5x the Lithium as compared to Graphite, thus making it far more suitable for increased Li-Ion battery performance. The researchers also demonstrated that the battery can work on over 10,000 cycles with only a 9% stability loss. So far, the team from Beijing has been able to successfully put the silk based material in prototype batteries as well as supercapacitors in a one-step method that can be easily scaled up to produce thousands of batteries.
