Lithium ion Battery VS Lead Acid

 

 

Lithium-ion batteries and lead-acid batteries are both rechargeable batteries. The main difference is as below:

Lead acid battery vs lithium-ion battery life

Lithium-ion batteries have a longer lifespan than lead-acid batteries, which means they can last for more cycles and years. Lead acid is 300-500 cycles for 2-3 Years, while lithium battery is over 10,000 cycles for 10 years.

Lead acid vs lithium-ion battery safety

* Corrosion: Lead acid batteries contain highly corrosive sulfuric acid and, if overcharged, can leak, releasing hydrogen and oxygen gases that can cause explosions. Lithium-ion batteries do not contain corrosive acid and are less prone to leakage, overheating, or explosion.

* Thermal runaway: Lithium-ion batteries are at risk of thermal runaway, a condition in which internal heat generation exceeds heat dissipation, which could give rise to an explosion. Lead acid batteries are less likely to experience thermal runaway, as they have lower energy density and higher thermal stability.

* Handling: Lead acid batteries are heavier and bulkier than lithium-ion batteries, which makes them harder to handle and transport. Lithium-ion batteries are lighter and more compact, which makes them easier to handle and transport.

* Disposal: Lead acid batteries contain toxic lead and acid, which can harm the environment and human health if not disposed of properly. Lithium-ion batteries contain less toxic materials but still require safe handling, storage, and disposal because they can cause short circuits or fire

Lithium ion battery vs lead acid voltage

Lithium-ion batteries and lead-acid batteries have different nominal voltages per cell. The nominal voltage is the average or typical voltage of a battery during discharge. The nominal voltage of a lithium-ion cell is 3.2 volts, while the nominal voltage of a lead-acid cell is 2 volts. This means that a lithium-ion battery can deliver more power per cell than a lead-acid battery.

Lithium-ion battery vs lead acid battery price

The price of a battery depends on various factors, such as the capacity, performance, quality, and brand of the battery. Generally speaking, lithium-ion batteries are more expensive than lead-acid batteries of equal capacity, but they also have higher performance and longer lifespan.

Difference between lead acid battery and lithium-ion battery charger

* Lead acid battery chargers typically deliver a constant voltage charge, while lithium-ion battery chargers typically deliver a constant current and constant voltage charge. This means that lithium-ion battery chargers are more efficient. The charging time of a lithium battery is half of an acid lead battery.

* Lead acid battery chargers have a built-in thermal sensor to detect overheating, while lithium-ion battery chargers have built-in protection against overcharging and overheating. This means that lithium-ion battery chargers are safer and can prevent damage to the battery cells.

* Lead acid battery chargers may cause the battery to become overcharged or undercharged, which can reduce the battery’s capacity and lifespan. Lithium-ion battery chargers can avoid these problems and maintain the battery’s optimal voltage and capacity. This means that lithium-ion battery chargers can enhance the battery’s performance and longevity.

Lead-acid battery vs lithium-ion battery mantenance

No Maintenance, no acid, and no corrosion for the lithium battery. However, lead acid batteries require regular maintenance, such as checking and refilling the electrolyte level, cleaning the terminals and connectors, and avoiding overcharging or undercharging.

Lead-acid battery vs lithium-ion environmental impact

Lithium battery is Pollution-free， and non-toxic, compared with lead acid. Lead acid may cause lead poisoning.

Efficiency

Lithium-ion batteries are more efficient than lead-acid batteries, which means they deliver more power and lose less energy during charging and discharging

Energy Density( Weight and Size)

Energy density: Lithium-ion batteries have a higher energy density than lead-acid batteries, which means they can store more energy in a smaller space and weight. The weight of a lithium battery is only 25% of an equivalent acid lead battery. On the opposite, the size of lithium battery is much smaller in the same capacity.

Lead acid battery vs lithium-ion battery for solar

In General, lithium-ion batteries are better than lead-acid batteries for most solar PV systems, especially those that require high power, long run time, and frequent cycling. However, lead-acid batteries may still be preferred for some applications that require low cost, high current, and infrequent use.

In conclusion, the lithium battery market will gradually replace lead-acid batteries in all aspects of life, such as trolling motor batteries, golf cart batteries, RV batteries, electric motorcycle batteries, scruber sweepers batteries, and so on.
