Some questions

  1. Do heavy metals from batteries in landfills pose a significant health risk?
  2. What ideas are being pursued to increase the number of usable cycles of rechargeable batteries?
  3. What causes some lithium batteries to burst into flames?
  4. Are there major breakthroughs in battery technology on the horizon? Is there steady progress?
  5. Some rechargeable batteries need to be discharged nearly completely each cycle to retain their ability to store charge. Why?
  6. How does the energy storage density of various battery systems compare?
  7. What is a typical open-circuit discharge rate? How is it influenced by temperature?
  8. Are there safety concerns about ultracapacitors? How do their charge retention properties compare to batteries?
  9. How do organic batteries work?
  10. What limits the charging rate? What is trickle charging?
  11. Do batteries cease to function when they are too cold? Is this a problem for electric vehicles?
