Aluminium-ion battery - Wikipedia

Aluminium-ion batteries are a class of rechargeable battery in which aluminium ions provide energy by flowing from the negative electrode of the battery, the anode, to the positive electrode, the cathode.When recharging, aluminium ions return to the negative electrode, and can exchange three electrons per ion. This means that insertion of one Al 3+ is equivalent to three Li +
