Abstract
Silicon-based composites are very promising anode materials not only for boosting the energy density of lithium-ion batteries (LIBs) but for realizing Li metal-free new battery systems such as Li–S and Li–O2.
Highlights
In our current society, energy and environmental issues have been recognized as top priorities among humanity's most pressing problems.[1,2] Due to the current heavy dependence on the usage of non-renewable fossil fuel, our society is facing climate problems mainly caused by increasing levels of atmospheric CO2
This contribution is focused on the development of advanced energy storage devices based on Li-ion batteries that can offer energy content beyond that is available with current lithium-ion batteries (LIBs) technologies
In order to boost the energy content of current LIBs to a level higher than is currently available with lower battery volume, graphite-based anodes have to be replaced with high capacity silicon-based anodes
Summary
Energy and environmental issues have been recognized as top priorities among humanity's most pressing problems.[1,2] Due to the current heavy dependence on the usage of non-renewable fossil fuel, our society is facing climate problems mainly caused by increasing levels of atmospheric CO2. We have to reduce the global atmospheric CO2 emission to a level (500 Æ 50 ppm) that prevents climate change in the future,[2] even though global energy demand continues to increase. Energy efficient electric vehicles are replacing current internal combustion vehicles. The adoption of these technologies can signi cantly reduce global carbon emissions if powerful energy storage devices are available
