AUNISOLBAT. Lead carbon technology batteries.
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.
Moreover, the carbon battery is ideal for partial state of charge (PSOC) applications. Hereby the cycle rate of the battery increases several times in comparison with the standard lead acid battery.
Despite its heavier weight and bigger volume perkilowatt hour the carbon battery is more cost effectivethan the lithium battery.
In terms of security the carbon battery is tried and tested for a long time and has no competitors. For transport, storage and usage no special measures are required. Due to its carbon additive,
The carbon battery is suitable for a much bigger temperature range than the standard lead acid battery. Unlike lithium batteries it doesn’t need a cooling system.
The recycling rate of 97% is one more pro argument for the carbon battery, since the recycling of lithium batteries remains an unresolved problem.
