Batteries for electric cars are extremely expensive. But Tal Sholklapper, the CEO of Voltaiq, a battery design consultancy, says that cost is coming down fast, and will soon reach $50-60 per kilowatt-hour. That’s about half of what it is now, and that would give EVs cost parity with piston powered cars and trucks. He also talks about battery recycling, a potential raw material shortage and other topics. Chad Kirchner from EVPulse.com also joins the discussion.
