The revolutionary energy storage The carbon battery is based on the lead acid technology. 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 carbon technology provides a solution for this problem: Using carbon guarantees much less sulfatization of the negative electrode. Thus, the battery can be charged up to 3 times faster (=0,3C) 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 thecarbon technology, since the charging current for the daily cycle mode can be adjusted at 20-30% of the battery capacity (= 0,2-0,3C). Therefore, it is possible to recharge a discharged battery within 1-3 hours. - Self-discharge: 3% of the capacity per month at 20°C - Max. charge current daily: 0.2C-0.3C - Max. charge current occasionally: 0.5C - Max. charge current : 3C - Norms: IEC 60896-21:2004, IEC 60896-22:2004
