SUMMARY

The discussion centers on the comparison of battery types based on their power capacity-to-size ratio. Lead-acid batteries, commonly used in cars, excel in delivering high discharge rates, providing substantial wattage for short durations. In contrast, lithium batteries offer superior total capacity, making them more efficient for long-term energy storage. The key takeaway is that while lead-acid batteries are powerful in terms of immediate output, lithium batteries are more advantageous for overall energy capacity.

PREREQUISITES
  • Understanding of battery chemistry, specifically lead-acid and lithium technologies.
  • Familiarity with battery ratings, including amp hours and milliamp hours.
  • Knowledge of power discharge characteristics and their implications for different applications.
  • Basic principles of energy storage and efficiency metrics in batteries.
NEXT STEPS
  • Research the specifications and applications of lithium-ion batteries.
  • Explore the discharge characteristics of lead-acid batteries in various scenarios.
  • Investigate advancements in battery technology focusing on energy density improvements.
  • Learn about the environmental impacts and recycling processes of different battery types.
USEFUL FOR

Engineers, battery technologists, and anyone involved in energy storage solutions will benefit from this discussion, particularly those interested in optimizing battery performance for specific applications.

what is the most powerful battery existing (by powerful i mean by power capacity/size ratio)
 
Computer science news on Phys.org
Do you mean how FAST or how MUCH? Lead/acid (car) batteries can discharge VERY quickly, so they can probably supply the most wattage (but for a short time), but lithiums have the most total capacity.

Batteries are typically rated for amp or miliamp hours and they are labeled as such.
