Lead carbon technology is a new generation of lead -acid battery technology. It combines the characteristics of supercapacitors and lead -acid batteries. Typical manufacturers are Nandu Power, Double Deng and so on.

Leaded carbon battery is a combination of carbon materials (C) with dual -electrode capacitance characteristics (C) and sponge lead (PB). Lead carbon composite electrode is matched with PBO2 positive pole to assemble into lead carbon batteries.

The circulating life of the lead carbon battery is 100%discharging depth is 3200, 80%of the cycle life under the depth of discharge is 2,500 cycles, which is much higher than the traditional lead -acid battery (about 1200 under 80%discharge depth) Essence This cycle life is close to ternary lithium and LFP technology.

Another main advantage of lead -carbon batteries is its low cost to large systems. The total price of lead -carbon batteries is less than half of the lithium battery. Considering that battery investment is the key part of the commercial BESS system, this can significantly shorten the recovery period. Safety is also a consideration for choosing lead carbon. Compared with lithium batteries, the chemical reactions of lead carbon batteries and anode are mild and slow, which makes it a safer technology.

The minimum charging time of the lead carbon battery at 100%discharge depth is about 5 hours, which is more than twice that of lithium batteries. When a fast discharge response is needed, the discharge performance of the lead carbon is lower than that of LFP, and the lead-carbon is not suitable for the fast response system, such as the frequency control system. But for arbitrage systems that do not need to be frequent and fast -operated, lead -carbon technology can meet the needs.
