CHEAP AND EFFECTIVE BATTERIES WITHIN REACH

BILLIGA OCH EFFEKTIVA BATTERIER INOM RAEKHAAL

Neither storage batteries nor dry batteries save energy or are satisfactory as regards the environment; many contain heavy metals. Recovery of metals is essential from the resources and environmental points of view. Several countries have comprehensive battery development programmes. The US has national programmes for balancing batteries and electric car batteries. Balancing batteries are the best means of storing energy in power supply systems. Present output of electric car batteries is 25 wh/kg. This has been doubled by the iron-nickel, iron-air and nickel-zinc batteries. The lead battery is the only one that can meet economic conditions governing power supply applications, but its life is limited by corrosion of the positive grid. Development of new electric car batteries concentrates on strongly electropositive and electronegative substances such as lithium-aluminium cathode, iron-sulphide anode and a licl-kcl eutectic electrolyte working at 400 degrees C. In the sodium-sulphur battery, the low conductivity of sulphur presents a problem. Best performance so far is 15 ah, 11 V and 77 wh/kg. The zinc-chlorine battery endeavours to achieve good performance and low cost. Of the factors first cost, efficiency and life, first cost is the most important. The alkaline lead battery combines low first cost and high performance. /TRRL/
