by lithium ion intercalation
Si has theoretical capacity of 4200mAh/g
Due to it’s large volume change, pulverization can be occurred.
Silicon has high-capacity but poor cycle stability
Carbon has low-capacity but good cycle stability
So silicon/carbon composites can have higher capacity than single carbon anode,
and better cycle stability than single silicon anode.
Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma

One of the most destabilising elements of the crisis has been the procyclical amplification of financial shocks throughout the banking system, financial markets and the broader economy. The tendency of market participants to behave in a procyclical manner has been amplified through a variety of channels, including through accounting standards for both ma

Of course, since the merger of 1967, the two companies (McDonnell Aircraft and Douglas Aircraft) were one company. However they were not completely merged. The lack of horizontal movement of executives among the various business units and ge
