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
