Storage batteries mechanism

The last group of parameters relates to handling of the batteries. These include the mechanical strength (e.g., with respect to vibrations and shock accompanying transportation), maintenance, and foolproofness (a term introduced by Thomas A. Edison in 1911 as one of the characteristics of storage batteries). 

This mechanism is followed in particular in the reactions of lead sulfate in the electrodes of lead-acid storage batteries. At the negative electrode. 

In topochemical reactions all steps, including that of nucleation of the new phase, occur exclusively at the interface between two solid phases, one being the reactant and the other the product. As the reaction proceeds, this interface gradually advances in the direction of the reactant. In electrochemical systems, topochemical reactions are possible only when the reactant or product is porous enough to enable access of reacting species from the solution to each reaction site. The number of examples electrochemical reactions known to follow a truly topochemical mechanism is very limited. One of these examples are the reactions occurring at the silver (positive) electrode of silver-zinc storage batteries (with alkaline electrolyte) ... 

The system, which is of practical importance (Edison storage battery, electrocatalysis in organic synthesis), is the NiOOH Ni(OH)2 couple (electrode). Somewhat surprisingly - since it is a widely studied and applied electrode - the mechanism and the true nature of the oxidized species are not fully understood yet [1, 2, 16]. The formal potential depends on the KOH concentration and is ca. 1.3 V. It follows that it is unstable in aqueous solutions and is also an oxidizing agent for various organic compounds. 

The most widely known use of lithium is the use of lithium carbonate in treating manic-depressive affective disorders the mechanism by which it alleviates depression in some people is not known. Industrially, lithium and its compounds are used in metal alloys, lubricants, nuclear reactor, coolant, ceramics, alkaline storage batteries, and electronic tubes. It is also used as a catalyst and as a reducing agent.

Lead, tin, and their alloys find some use as engineering materials. Both lead and tin are mechanically soft and weak, have low melting temperatures, are quite resistant to many corrosion environments, and have recrystallization temperatures below room temperatme. Some common solders are lead-tin alloys, which have low melting tem-peratmes. Applications for lead and its alloys include x-ray shields and storage batteries. The primary use of tin is as a very thin coating on the inside of plain carbon steel cans (tin cans) that are used for food containers this coating inhibits chemical reactions between the steel and the food products. 

Abuse tests for smaU consumer cells are defined by the hitemational Electrotechnical Committee (lEC), Underwriter s Laboratories (UL), and the Japan Storage Battery Association (SBA). For electric vehicle batteries, the USABC has developed a test manual that is available from Sr E [39]. The USABC manual classifies abuse tests as mechanical, thermal, electrical, and vibration. In Europe, ASTOR is developing standards for advanced automotive batteries [40]. There have been only a few reports on the abuse behavior of large cells.
