Bulk-type all-solid-state inorganic Li-ion batteries can be prepared in one step in few minutes using spark plasma sintering. The self-supported cells display thick composite electrodes of up to 800 μm, which offer high surface capacities of up to 10 mAh.cm−2. Such technology is safer than classical Li-ion batteries and offers good electrochemical properties at temperatures above 100 °C.
