Silver zinc cells Wide use in industy High energy density, high discharge rate capal ability, fast response Short lifetime Vent gas during discharge Potentially rechargeable but few cycles
Silver Zinc Cells • Wide use in industry • High energy density, high discharge rate capability, fast response • Short lifetime • Vent gas during discharge • Potentially rechargeable but few cycles
Lithium cells Higher energy density than silver zinc Wide temperature range Low discharge rate(high internal Impedance) Rapid discharge may cause rupture Slow response
Lithium cells • Higher energy density than silver zinc • Wide temperature range • Low discharge rate (high internal impedance) – Rapid discharge may cause rupture • Slow response
