For instance, lead-acid batteries with an energy density of 30–40 Wh kg –1 and power density of 180 Wh kg –1 are a long way off from being feasible as storage devices . Other types of secondary batteries such as nickel-cadmium batteries have also a relatively low energy density of 45–80 Wh kg –1 .
In 2016, a University of Maryland team reported an aluminium/sulfur battery that utilizes a sulfur/carbon composite as the cathode. The chemistry provides a theoretical energy density of 1340 Wh/kg. The prototype cell demonstrated energy density of 800 Wh/kg for over 20 cycles. [ 33 ]
Lithium (Li)-ion-based technologies are currently dominating the battery market with energy density in the range of 250 Wh/kg. The targets are to reach 350 Wh/kg by 2025 and 500 Wh/kg by 2030, which will effectively reduce the battery weight to a half.
In fact, no Al-based battery has been shown with the required stability or touted energy density. Typically, the performance of Al-based batteries is overstated in the literature due to imprecise considerations that do not fairly evaluate practically achievable energy densities.
Aluminium-ion batteries are a class of rechargeable battery in which aluminium ions serve as charge carriers. Aluminium can exchange three electrons per ion. This means that insertion of one Al 3+ is equivalent to three Li + ions.
Aluminium-ion battery (AiB) has high capacity (2980 mA h g −1 or 8046 mA h cm −3) and is considered a promising energy storage device for large-scale applications. Generally, non-aqueous electrolytes are used for AiBs which suffer from the high cost and safety concern .
