Depending on how it is built, there are batteries that are renewable. You are right there are going to be some waste regardless, but it is no different than the production of oil.
The life of hybrid car batteries are way longer than what people perceive. Why do you think most hybrid batteries carry a 6-8 years warranty? I believe Hyundai's latest hybrid battery retain 90% of its original power even after 150K, the same goes to Toyota.
