Boris Monahov

Bio
Boris Monahov devoted 43 years to batteries, mainly lead-acid. His experience includes 25 years of basic electrochemical research (with the team of Prof. D. Pavlov as Associate Professor), followed by 6 years of research and technology development in the battery industry as Chief Electrochemist of Firefly Energy Inc., USA (lead ― carbon foam batteries). For 9 years (in the period 2010-2018, three 3-years programs) he was Program Manager of the Advanced Lead-Acid Battery Consortium (ALABC), a global battery R&D organization found in the USA where he managed three consecutive multi-project research programs (over 25 projects) for the battery industry. Since 2019 he has been managing the global R&D battery optimization program of WaveTech Group. The company develops new methods for increasing the power performance and extending the service life of batteries.
He has published over 60 articles on battery electrochemistry and has 5 patents. Boris is an active member of the Electrochemical Society. In 2012 he was awarded EPLS’s BEST magazine award for outstanding technical contributions by an individual to the lead-acid battery industry. In 2014 he was awarded by the Gaston Plante medal of the Bulgarian Academy of Sciences for fundamental contributions to the lead-acid battery science and technology. Boris Monahov is habilitated (1996) as senior research scientist by the Bulgarian Academy of Sciences. He holds a PhD degree in electrochemistry from the Bulgarian Academy of Sciences (1994) and a master’s degree in solid state physics from the University of Sofia, Bulgaria. Currently, Dr. Monahov is Chief Science Officer at WaveTech Group.
Cycle life is a major battery performance parameter. WaveTech Group has developed a unique charge pulse profile based on modifying the kinetics of ionic movement in lead-acid cells, called CCT®. This enhances the microstructure of the NAM and PAM. The corrosion rate becomes lower, no extra heat is evolved and the gassing rate is reduced. The electrochemical processes in the cells are optimized. As a result, cycle life is doubled. Less frequent replacement along with enhanced operation of VRLA monoblocs reduces undesired expense and reduces the battery total cost of ownership. WaveTech has performed series of field tests studies with large telecom operators in Europe, Asia, and Africa, with a global UPS manufacturer, as well as with a large lead battery manufacturing company. The benefits were confirmed. In our presentation laboratory and field test results will be shown to illustrate the effect of CCT® in flooded and AGM VRLA batteries, as well as in battery manufacturing (formation). This has shown that the rate of capacity loss of VRLA Batteries in telecom sites has halved. The use of CCT® in UPS systems demonstrated an extension of cycle life. A battery recovery system for various sizes of 12 V VRLA monoblocs (5 Ah to 250 Ah) was developed. The use of CCT® allows reduced formation time and lower energy costs. Batteries formed with CCT® have better cold cranking ability and longer cycle life at PSoC after formation. CCT® can be combined with our precise battery monitoring system. The CCT® method was adapted to LFP batteries. They achieved 20% longer cycle life, higher energy throughput and improved performance at -10°C.
