The revolutionary energy storage
Unlike lithium batteries standard lead acid batteries have a big discharge capacity (up to C3*). Indeed, a much longer charging time (up to 10 hours, =0,1) must be accepted to prevent sulfatization which would shorten the lifetime of the battery. The new lead carbon technology provides a solution for this problem: Using carbon additives guarantees much less sulfatization of the negative electrode. Thus, the battery can be charged faster than a standard lead acid battery.
Modern lithium battery sytems can also be charged within less than an hour, but the discharge capacity is very low: It must not exceed 50-70% of the battery capacity (= C0,5-07). The fast charging is a significant progress in lead carbon technology, since the charging current for the daily cycle mode can be adjusted at 20-40% of the battery capacity (= 0,2-0,4C). Therefore, it is possible to recharge a discharged battery within several hours.
