A lithium-ion cell designed to be used to power a mobile phone will be very energy dense , because it does not need to discharge quickly. On the other hand, a lithium-ion cell designed to be used in a hybrid electric vehicle will be rate capable . A rate capable cell will have a larger specific energy, compared to an energy dense cell. An energy dense cell will have a internal resistance, compared to an rate capable cell. Would you expect a larger proportion of in an energy dense lithium-ion cell, and consequently each layer of the cell would be . Lithium-ion cell resistance tends to increase as temperature is increased .
