Electrochemical battery

The appearance of electrochemical batteries provided an impetus in research into practical applications of electric current. The first prototype of electric telegraph appeared in 1804. In 1838, Jacobi experimented with a battery-driven motorboat on the Neva River not far from St. Petersburg. These achievements led to rapid development of the theory and practice of electrical engineering, and the seventh decade of that century saw the appearance of a revolutionary new power source the electromagnetic generator (Werner von Siemens, 1866), which soon surpassed their predecessors in both electrical and economic parameters. 

Fuel cell vehicles are viewed as one of the best long term options. A hydrogen fuel cell vehicle has advantages over alternatives, such as hybrid vehicles which combine IC engines with electrochemical batteries and still require petrochemical fuels that exhaust carbon dioxide and pollutants. 

New battery developments include the ultracapacitor hybrid barium titan-ate powder design (EEStors). These devices can absorb and release charges much faster than electrochemical batteries. They weigh less, and some projections suggest that in electric cars they might provide 500 mi of travel at a cost of 9 in electricity. But these are only the projections of researchers. 

Direct current (DC) can be stored in rechargeable electrochemical batteries (Pb acid, NiCd, Li ion cells). So far, alternating current (AC) cannot be stored practically, but must be generated and used as needed. Storing electrical currents in superconducting rings with zero power loss is possible, but not cost-effective (practical superconducting materials must be kept at...

Cell - A component of a electrochemical battery. A primary cell consists of two dissimilar elements, known as electrodes, immersed in a liquid or paste known as the electrolyte. A direct current of 1-1.5 volts will be produced by this cell. A secondary cell or accumulator is a similar design but is made useful by passing a direct current of correct strength through it in a certain direction. Each of these cells will produce 2 volts a 12 volt car battery contains six cells.

In 1859, the French scientist Gaston Plants (1834-1889) made the first prototype of a lead acid rechargeable battery. An alkaline nickel-cadmium rechargeable battery was developed in 1899 by the Swedish engineer W. Jungner (1869-1924) and an alkaline nickel-iron battery was developed two years later by the well-known American inventor Thomas A. Edison (1847-1931). Up to the seventh decade of the nineteenth century, electrochemical batteries remained the only sources of electrical current and power.
