8. Solid-state battery - Wikipedia

   en.wikipedia.org/wiki/Solid-state_battery

   A solid-state battery is an electrical battery that uses a solid electrolyte for ionic conductions between the electrodes, instead of the liquid or gel polymer electrolytes found in conventional batteries. [ 1] Solid-state batteries theoretically offer much higher energy density than the typical lithium-ion or lithium polymer batteries.

9. iPhone 3GS - Wikipedia
