The lithium insertion and extraction dynamics of spinel LiMn 2 O 4 /carbon composite electrodes used in lithium-ion batteries have been investigated. A numerical model has been developed which rationalizes these electrodes as a bed of spherical Li 1−δ Mn 2 O 4 particles (0≤δ≤1, depending on the degree of insertion) with carbon as an electrically conducting additive,...
A formal, theoretical model of the dynamic structure of tourism demand is developed from consideration of information flows. The result is a nonlinear, diffusion form of model specification. Such models are estimated for seven major sources of tourists to Australia. The estimation results show that incomes have a key role in explaining international tourism to Australia. Income elasticities vary...
