Ultra-Lead Carbon Foam Battery
Carbon foam Lead acid battery (CLAB):
- Porous carbon materials show interesting properties. The empty spaces of our proprietary carbon foam electrodes comprise 90–97% of its volume, which ensures their high surface-to-volume ratio.
- The electrode material also has good electrical conductivity and active mass holding capacity.
- The replacement of a standard grid in a lead-acid battery with our carbon foam matrix leads to the reduction of battery weight and lead consumption of about 20%.
- Additionally, a spatially (3D) cross-linked matrix collector with small distances (5 mm or lower) between the ribs increases the efficiency of the charge collection from the active mass introduced into the pores.
- Considering the difference in the materials and the production costs of classic grids and modified carbon matrix, the production of CLAB leads to a decrease in costs.
- These savings will be equivalent to the reduction of the used lead corresponding to around 30% of the total weight of a standard battery.
- For example, the weight of a CLAB with a 75 Ah capacity is about 16 kg, while a comparable standard battery with the same capacity weighs up to 23 kg.
- In other words, for a similar weight battery of LABs and CLAB, the cell capacity and hence the energy density are increased to an appreciable extent.
Benefits of Ultra-Lead Carbon Foam Battery
•Operates at subfreezing temperatures
•Does not need active cooling
• Low Creep
Unlike regular lead acid, lead lead-carbon can operate between 30 and 70 per cent per of charge without fear of becoming sulfated. The ULC is said to outlive the regular lead lead-acidity, but the negative is a rapid voltage drop on discharge, resembling that of a supercapacitor
