Standard lead-acid batteries have a big advantage over lithium batteries, a large discharge capacity (up to C3). But to counter sulphation that would greatly reduce the life of the battery, there is a much longer charge time with lead-acid batteries (up to 10 hours = 0.1). The new Lead Carbon technology offers the solution here:
The negative plates of these batteries are made from lead and carbon and thus combine the advantages of normal lead-acid batteries with those of a supercapacitor. The addition of carbon ensures that these batteries have a higher charge acceptance and therefore have to charge for less time than regular lead-acid batteries. Moreover, they provide more power and are more resistant to (extremely) low temperatures. By adding Lead (pb) to the negative plate there is also less resistance resulting in a longer life. In addition, this latest technology suppresses sulphation better than any other technology.
