Advanced Lead-Acid: | ||
Since Gaston Plante, for the first time demonstrated a rechargeable Lead-acid battery in front of French Academy of Science on March 26th, 1860, Lead-acid batteries have been a work horse to provide portable energy in almost every areas in our life. Only until in the past a few decades, rechargeable Ni-Cd, Metal –hydride and now the state-of-art Li-ion batteries are gradually replacing lead acid in many applications, in which high energy density and high portability are essential e.g. cell phone, lab top computer, hybrid and plug-in electric vehicles. The largest markets for lead acid batteries are SLI battery (starting, lighting and ignition) for the vehicle engines and storage battery e.g. for UPS (uninterruptible power system). The technology advancement had been stagnant till the quick proliferation of Start n’ Stop application in the internal combustion vehicle. The advanced AGM (Absorbent Glass Mat) and EFB (Extended Floored Battery) started to surface especially in past a few years. The AGM design aimed to mitigate the following three shortcomings for a lead acid battery.
