1 Advanced lead-carbon battery
Power storage may be the big story in renewable energy in the next few years, thanks to a proliferation of battery chemistries. Lithium-ion varieties, however, may be overshadowing other chemistries, such as flow batteries and the always evolving lead-acid. Consider, for example, Axion Power International’s (www.axionpower.com) lead-carbon, or PbC battery. The company calls it an advanced lead-acid design because it replaced the negative lead plate with an activated carbon plate giving the battery unusual characteristics, such as super-capacitor qualities. In addition, the PbC design uses the same caustic plate as a lead-acid battery along with components, casing, and electrolytes, and it’s recyclable.
