The book on lithium is only at Chapter two and there would appear many chapters yet to be written. Time and science will tell and not your mere scribe.
The major attractions to lithium centre around how light (third lightest when classified as a refined metal) lithium becomes, making it ideal for batteries when combined with the ability of the metal to receive and exude electric current efficiently, as and when required. It would be fallacious to suggest Lithium is the only metal that has these properties and readers need to take into account how fast science is moving into other alternatives (e.g., into sodium that is very abundant and should be a cheap source as well as zinc-air and zinc-bromine). This scientific explosion is partly driven by the fact that lithium has doubled in price over the last 12 months and partly by the climate change pressures to move from fossil fuels into more friendly energy technologies.
The compounds of this metal are used widely in the manufacture of ceramics, glass and consumer electronics and are an essential element in long life lithium ion batteries in cars, mobile phones and similar devices. There is also a lot of research going into mass energy storage generated from renewable energy sources, with lithium-ion batteries presently at the forefront. Just how big an international market for lithium compounds will be into the future is just too difficult to predict, so forecasts need to be taken carefully and with considerable personal research. Based on comments contained in a range of annual reports to the ASX and available on their respective websites, the immediate future for lithium and lithium producers appears very healthy.
