A High-Energy Solid State Battery with an Extremely Long Cycle Life
Cycle life and coulombic efficiency of a 5V solid state lithium-ion battery
A high-voltage (5V) solid state battery has been demonstrated to have an extremely long cycle life of over 10,000 cycles. For a given size of battery, the energy stored in a battery is proportional to its voltage. Conventional lithium-ion batteries use organic liquid electrolytes that have a maximum operating voltage of 4.3 V. Operating a battery above this limit causes short cycle life and serious safety concerns.
