SOLID STATE BATTERY
MATERIALS
Negative electrode
The dominant negative electrode material used in lithium ion batteries.
output, charging time, durability
High specific energy
greater storage capacity
moderate density (2 A·h outputs 70 amperes) High safety compared to Cobalt / Manganese systems.
Larger capacity than a cell with graphite
Energy density: ~74 mAh/g.
good specific energy and specific power density
Positive electrode
ADVANTAGES
safer
