High power nanophosphate batteries under test

Lithium-based chemistries have for some time been showing the most promise of all battery technologies. Although they offer an unsurpassed energy density they are difficult and expensive to manufacture and require careful handling and gentle charging. Things could be about to change with the introduction of nanotechnology into the manufacture of the cathode. The author tested some of the first examples of these new Li-ion units for Elektor Electronics, with results varying from the merely respectable to the sensational!
