Copper is 70% the weight of lead, but sixteen times as conductive as lead. Hence, the specific energy of lead-acid battery was increased up to 35–50 Wh kg −1 in contrast to conventional lead-acid batteries. Interestingly, this substrate has the potential to be used as a bipolar substrate for lead-acid batteries.
Future of bipolar lead-acid batteries. Despite lead-acid production facilities being quite appealing in terms of scale, cost, and recycling; low energy density positions the lead-acid battery at the bottom of the Ragone plot of electrochemical systems.
Lead carbon batteries (LCBs) offer exceptional performance at the high-rate partial state of charge (HRPSoC) and higher charge acceptance than LAB, making them promising for hybrid electric vehicles and stationary energy storage applications.
According to the authors, if all those new developments were introduced successfully, then the bipolar lead-acid battery could attain specific power of 500 W kg −1.
