Starting from the 1850 s Sinstede and planté early start-up era, the history of lead-acid batteries can only be called extraordinary for a simple arrangement of lead and sulfuric acid that provides a power source for the whole world.It is also unusual that change has been so small in the past 150 s.For example, otto Jache may have invented the gel valve to regulate lead-acid batteries in the late 1950 s, but the product did not start real development until it was in its 1970 s, it was almost 10 years before it came out to deploy AGM technology.So the last big thing in technologyAnyway-It's already a generation.The mentality of "It's not broken, so don't fix it" used to look like it was branded with industry DNA.Search is almost always offering better, more commercial products --Witness the arrival of polypropylene SLI batteries in the medium termMaintenance free batteries at 1960 and later-.However, the basic chemical properties of the battery are still not challenged or changed.Lead-acid batteries are considered a rust belt technology for some reasons --In fact, they barely changed in a century, just re-This is emphasized.With technology advancing by leaps and bounds in almost all other industries around the world, the world is starting to be obsessed with what they think is the future of batteries: products based on rare metals such as nickelLithium hydroxide metalion batteries.We have been told that they will be lighter, cheaper and more efficient.Lead-acid already exists over the 100 s, and many believe it is an old technology that cannot address the new needs of today.This is true for many applications.Nickel and lithium-Ion batteries are ideal for portable electronic devices such as mobile phones, laptops and small power tools, which are unlikely to change.They are light and produce a steady current for a long time.But for applications that require higher power and larger storage capacity, the efficiency and security of these products are questionable.There is a question mark on the future availability and cost of raw materials required to manufacture these products, and their recovery rate is much lower than that of lead-acid batteries..The new attractive technology still fails to provide mass production products for some of the largest battery users such as our vehicles.But lead-acid batteries have been doing these twoup and re-Sure their status is still (almost) the only game in town worth playing
