9 misconceptions about Tesla batteries

Elon Musk recently announced Tesla's new home battery - the Tesla Powerwall. Due to all the hype and misunderstanding around batteries, what are some of the most common misconceptions about Tesla batteries? Here are 7 common myths about these innovative technologies
  1. Tesla batteries blow up - it never happened, they are separate chambers. There is no option to blow up.
  2. They're fire hazards - not a problem. Stats show this is less likely than petrol cars and hybrids. Following this logic, hybrid materials should be twice as dangerous as Tesla batteries.
  3. The materials for Tesla batteries are mined by children - not accurate. The material in question is cobalt. Tesla has put great effort into making sure this is not the case, and Tesla has switched to iron based batteries instead of cobalt.
  4. Production of Tesla batteries is more environmentally destructive than the batteries could possibly provide green benefits. Not true. Also it's worthwhile to mention that Tesla cars have the best efficiency in the world. A Tesla 75kwh battery is the equivalent of a 90kwh competition battery installation.
  5. Lithium is a rarer material. No way. It is one of the most abundant materials on this planet
  6. Tesla batteries take a long time to charge, This is also untrue! Tesla batteries can be charged very quickly, Thanks to Tesla's extensive fast charging network, automatic battery preconditioning, and exceptionally long range, you'll drive for longer. Superchargers can add up to 200 miles of range in just 15 minutes.
  7. Tesla batteries are too expensive for the average person, While Teslas do tend to be more expensive than other types of cars, their batteries are actually cheaper than most other types of batteries on the market plus, they last much longer.
  8. Tesla batteries will degrade in efficiency and become ineffective like smartphone or laptop batteries over time. Tesla batteries are designed to withstand up to 1 million miles. The average lifespan of a modern car is less than a million miles, so the batteries will outlive the car. Tesla is so confident about it that its batteries come with an 8-year warranty. Is this the case for combustion engine motors in ICE cars? I don't think so…
  9. Tesla batteries are an environmental hazard after they are used and pollute the environment. Engine used oil is a hazardous substance after every 10k miles, and mechanics are just spilling it on the grass. Tesla batteries are 90% recycled and put back into new batteries, while Panasonic and redwood materials buy them back and sell them back to Tesla immediately as raw materials.
