Tech News 1: Beyond lithium: A systematic search for candidate materials for calcium-ion batteries

[bob_turner]

Electric cars are the future; they will help reduce air pollution and end our dependence on fossil fuels. However, there is one glaring problem with this potentially disruptive technology: the availability of sufficient lithium (Li) to produce all these car batteries. The best rechargeable batteries we currently have are based on chemical reactions involving Li, which is why one finds Li-ion batteries in most portable electronic gadgets. Unfortunately, Li is not abundant on earth, and its reserves...
