a sulfur battery has been developed (it will be years before it is on the market) that is even less toxic, cheaper to build, holds far more power than the best batteries now in use, and charges faster. the best argument for battery use is "if we don't use them, we will never have the chance to develop better battery technology"
In reading the article from http://www.hybridcars.com/hybrid-battery-t oxicity/ it says: "While batteries like lead acid or nickel cadmium are incredibly bad for the environment, the toxicity levels and environmental impact of nickel metal hydride batteries—the type currently used in hybrids—are much lower."
I was talking with a college student (Who knows everything as each and every college student does!) and he was telling me how bad solar batteries are and also batteries for hybrids such as the Prius. According to him, They are composed of really toxic materials and the harm they will do to the environment when they have finished their lifespan and are dispoded of, will overly offset any good that they did during their life.
