This makes a difference of +9 °C compared to the reference case. Yet, the cell goes faster into the thermal runaway. It can be concluded that SEI composition has a notable effect on thermal safety of a battery, with cells with more LEDC, e.g. due to less ageing, being more likely to enter a thermal event, leading finally to thermal runaway.

Two types of extrinsic (impure) semiconductive materials, n-type and p-type, are the key building blocks for most types of electronic devices. Since semiconductors are generally poor conductors, their conductivity can be drastically increased by the controlled addition of impurities to the intrinsic (pure) P.
Let us now consider an n-type material having NA = 0. Since the number of electrons is much greater than the number of holes in an n-type semiconductor (n > p), eqn.(3) reduces to ND ˇ n (4) In an n-type material the free-electron concentration is approximately equal to the density of donor atoms. The concentration of holes in the n-type semicon-
