The battery separators currently used by most flooded-cell-type lead acid battery manufacturers are of the microporous PE type. It was invented in the late 1 %0s by W. R. Grace Co. [193]. The term polyethylene separators is somewhat misleading, since such a separator consists mainly of agglomerates of precipitated sUica, being held within a network of extremely long-chain UHMWPE [194]. A typical PE... 

Lead-acid batteries can be classified into three major types or categories, namely, automotive (SLI), stationary, and motive power (industrial). In addition, there are many special batteries that cannot be easily categorized as either of the above types. As these types of batteries are constructed with different materials and design to meet the requirements of their intended end uses, each requires a particular separator with specific material composition, mechanical design, and physical, chemical, and electrochemical properties that are tailored for the battery and its relevant specific uses. These batteries are generally available in flooded electrolyte or valve regulated (sealed) versions. In this section the types... 

Different types of lead-acid batteries have been developed as energy sources for many power applications, like traction and backup or standby power systems. The flooded lead-acid batteries have an excess or flooded electrolyte and they were the largest used at the beginning of the last century for many applications. Valve-regulated lead-acid (VRLA) batteries were developed as an alternative to the flooded lead-acid batteries, in order to maintain levels of distilled water and prevent drying of cells, which means safe operation for battery packs in electric... 

The classical scheme for the manufacture of flat pasted plates for automotive, traction and stationary lead-acid batteries is shown in Fig. 3.1. There is no difference between the technology of plate manufacture for conventional (flooded) and valve-regulated (VRLA) lead acid batteries. The two versions do differ, however, in the method of separation of the plates, the quantity and type (hquid or gel) of electrolyte, and in the design of the battery itself. 

Lead-acid batteries are one of the most common type of batteries. Most lead-acid batteries are flooded, that is.

Historically, subsequent to exploratory studies on lead-acid systems by Daniel, Grove and Sindesten, practical lead-acid batteries began with the research and inventions of Raymond Gaston Plante in France as early as 1859 and, even today, lead-acid battery remains the most successful battery system ever developed. There are three types of lead-acid batteries in common use (1) batteries with flooded or excess electrolyte, (2) low-maintenance lead-acid batteries with a large excess of electrolyte and (3) batteries with immobilised electrolyte and a pressure-sensitive valve, usually referred to as valve-regulated lead-acid (VRLA) or sealed lead-acid (SLA) batteries [3]. 

Starved electrolyte battery — A -> battery with minimum amount of -> electrolyte. The electrolyte in starved electrolyte cells or batteries exists in the porous structure of the - electrodes and absorbed in the separator, so it contains little or no free fluid electrolytic solution. This type of batteries is used in certain constructions of sealed - lead-acid and -> nickel-cadmium batteries that rely on gas diffusion and recombination on the electrodes during charging or overcharging in order to maintain maintenance-free conditions, and to suppress pressure buildup. Starved electrolyte batteries benefit from larger - energy density due to the reduced amount of electrolyte. This design may suffer from poor heat dissipation compared with -> flooded batteries, thus for high power applications this point has to be taken into account.
