Lithium-ion vs Lead-Acid cost analysis

We take the example of a solar installation for a standalone building (Self Sufficient Home).The storage capacity for the battery is 50KWh.

The application need is summarized in the above table:

SPECIFICATIONS VALUE

Stored Energy
50KWH
Cycling frequency 1 x discharge/charge per day
Average ambient temperature 23°C
Expected Lifespan 2000 Cycles, or 5.5 years
 

 

 

Major advantages of Lithium Iron Phosphate:

Very safe and secure technology (No Thermal Runaway)
Very low toxicity for environment (use of iron, graphite and phosphate)
Calendar life > 10 ans
Cycle life : from 2000 to several thousand (see chart below)
Operational temperature range :up to 70°C
Very low internal resistance. Stability or even decline over the cycles.
Constant power throughout the discharge range
Ease of recycling
