| Lead Battery raw material lead Lead accumulators Lead accumulators Leyden jar The first Capacitor developed in 1745, also called the Kleist jar. In its simple version it was a water-filled glass jar through whose cork a spiral electrode was inserted that was submerged in water. Lithium Lithium Lithium-iron sulphide battery Thermoelectric battery with Anodes of lithium-aluminium or lithium-silicon alloys. The cathode consists of iron sulphide, a molten salt (lithium/ potassium chloride) is used as an electrolyte. Lithium-iron sulphide batteries are special batteries for the military sector. Lithium-iodine battery Battery system for very high demands on reliability, efficiency (typical energy density: 240 Wh/kg) and longevity (5 to 10 years), e.g. for pacemakers. Lithium-ion-accu Lithium-ion accumulator Lithium-silver vanadate battery Special battery for cardiac defibrillator implants. Manganese Manganese Mechanically chargeable battery Metal-air battery Memory effect Memory effect Mercury Mercury Metal-air battery In a metal-air battery the anode metal (e.g. Iron, Aluminium or Zinc) is oxidised in an alkaline Electrolyte whereas atmospheric oxygen is converted with water to hydroxide ions at the Catalytic Cathode. The manufacture of the cathode poses great technical difficulties, particularly in rechargeable systems, so that no industrial system has yet been produced. This battery is used as a traction battery in experiments for commercial vehicles or as an emergency power store. With the aluminium-air type in particular the metal can be mechanically exchanged when the battery is spent and the battery thus recharged. This type is also called a 'mechanically rechargeable battery'. © Marc Stenzel
