Abstract
The invention relates to a process for making sodium-ion cells, particularly sodium-ion cells which are capable of safe storage and/or transportation, comprising the steps: a) constructing a sodium-ion cell comprising a positive electrode, a negative electrode and an electrolyte, optionally performing one more charge/discharge operations on the sodium-ion cell; and b) treating the sodium-ion cell to ensure that it is in a state of charge of from 0% to 20%.
