Emerging Technologies for Batteries—Several New Vectors of Research
Nickel Cadmium used to be the standard but due to environmental concerns about cadmium, Lithium Ion now holds 75% of the market.
Another technology on the horizon is the all liquid active materials which uses molten metals for the electrodes and a molten salt for the electrolyte. The resulting design generates 10x the power over a traditional power design.
Alternative energies such as wind are pushing the envelope on battery technology itself. In this example sodium sulfur batteries are used to reduce the intermittency problem with wind energy.
Another dimension of batteries is the environmental friendliness of the battery with respect to disposal. In this example, Fuji’s battery is free of cadmium, mercury, and PVC, which will soon be regulated out of landfills by some countries.
