Options:

  1. Lithium moves automatically from high-concentration regions of the compound to low-concentration regions of the compound via diffusion
  2. The compound must have an open crystal structure, allowing insertion or extraction of lithium ions in the vacant spaces
  3. When Li^++ enters the compound, the compound also must have an ability to accept compensating electrons from the external circuit
  4. Lithium forms a strong chemical bond with the compound when it intercalates into its crystal structure

All correct answers are:

  1. Lithium moves automatically from high-concentration regions of the compound to low-concentration regions of the compound via diffusion(Yes. This is the principal mechanism for lithium movement inside an electrode particle.).
  2. When Li^++ enters the compound, the compound also must have an ability to accept compensating electrons from the external circuit. (Yes. This is how electrical current flows).
  3. The compound must have an open crystal structure, allowing the insertion or extraction of lithium ions in the vacant spaces. (Yes. This is how lithium enters or exits the electrode.).
