In 1881, Gustave Trouve in France built a trike powered by a rechargeable lead-acid battery. Over nearly two hundred years, power battery technology has developed from lead-acid batteries and nickel-cadmium batteries to nickel-metal hydride batteries. However, these batteries were unable to meet the technical power requirements.
The separator is one of the most critical components of the lead/acid battery. Too often, its role in determining performance and life is ignored. ... Excellent performances and lives have been obtained using flat types of separator by applying this method of design as the pressure of the separator on both positive and negative materials ...
The common design of lead–acid battery has ''flat plates'', which are prepared by coating and processing the active-material on lead or lead–alloy current-collectors; see Section 3.4.1. One alternative form of positive plate has the active-material contained in tubes, each fitted with a coaxial current-collector; see Section 3.4.2.
The valve regulated lead acid (VRLA) battery is a predominant electrochemical storage system that stores energy in a cheap, reliable and recyclable manner for innumerable applications. The absorptive glass mat (AGM) separator is a key component, which is pivotal for the successful functioning of the VRLA battery.

The incidence of dendritic shorts can, therefore, be reduced by; shortened stand times (∼30 min); maximized filling-acid densities; lower filling-acid temperatures (to reduce the rate of reaction); where possible, even distribution of the acid throughout the plates and the separators; if the battery design and cost permits, increased ...
China produces around 80% of the world''s separators. Out of these, 70% are wet process separators and 30% are process separators. As NMC battery are targeting higher energy density, manufacturers are mostly using wet separators. This is due to wet separators are 30%-40% thinner than dry separators, it can save more space for other components.
