- •
The diffusivity of Li in a-Si was investigated via finite element simulations.
- •
The in-situ TEM nanosphere lithiation experiments were simulated.
- •
The value was estimated at 2 × 10−17 m2/s for Li poor phase in the first lithiation.
- •
The value was about 2 × 10−15 m2/s for Li rich phase in the first and subsequent lithiations.
