چکیده
With the massive application of lithium-ion batteries (LIBs) in portable devices and electric vehicles, supplying active materials with high performances then recycling their waste are two core issues for development LIBs. Herein, a novel strategy is proposed to recycle spent LIB (SLIB) graphite reform it as valuable anode material SLIB has been carbon-coated using glucose (OSG@C). We systematically investigated effects coating amount, carbonization temperature, time on performance OSG@C. As an LIBs, reconstructed exhibits outstanding electrochemical performance. The can deliver capacity 424.7 mAh g−1 over 270 cycles at 1C, also displayed rate capability (a 212.8 achieved 5C). improvement attributed layer large interlayer spacing abundant micropores, which speeds up transport Li+. findings demonstrate great potential be reused high-performance LIBs via simple treatment.

متن کاملFabrication of 3D carbon microelectrodes for Li-Ion battery applications
The fabrication of very high-aspect ratio 3D carbon microelectrodes for Li-Ion batteries is presented. Using a pyrolysis process under inert conditions, thick layers of patterned SU-8 photoresist (up to 600 μm in height) are converted into carbon. The micro-structures resulting from this process are used as anode for a Li-Ion battery. A detailed explanation on how to create SU-8 structures of a...
متن کاملModelling Li Ion Battery Electrode Properties
In recent years, interest in using lithium-ion (Li-ion) batteries as power sources for a wide range of devices (particularly portable devices) has grown significantly. There is thus a real need to understand at a fundamental level a wide range of battery performance criteria (energy density, power density, safety, durability, cost). Our working group considered how to model the fundamental elec...
