ABC has successfully designed a bipolar, lead-acid battery and developed and implemented a commercially viable manufacturing process.
The theory behind bipolar batteries has existed for almost a century. First developed by Nobel laureate Pyotr Kapitsa in 1924 bipolar designs differ from traditional prismatic designs by replacing heavy metal grids connected by a top-level, cast-on-strap, (Figure 1(a)) with a conductive plate having positive material on one side and negative material on the other side (Figure 1(b)).
The advantages of bipolar batteries have long been known.
However, practical concerns around the actual battery design and manufacture have prevented anyone from developing a commercially viable bipolar battery until now.
Over the past five years, through the development of a number of new manufacturing technologies and an innovative battery design, Advanced Battery Concepts has successfully solved those problems and produced both a bipolar battery ready for large-scale production and the manufacturing processes to go with it.
