What do sodium-ion batteries contain?
Na-ion batteries are home to sodium in the cathode (positive terminal), sodium in the electrolyte (separator), and hard carbon to make the anode (negative terminal). On each electrode side, there’s an aluminium current collector for both the cathode and anode.
The anode’s hard carbon material allows a broader range of available electrolytes, resulting in a wider operating temperature range is possible and ultimately makes it safer to use.
