1. Different properties
1. Lead-acid battery: A battery whose electrodes consist primarily of lead and its oxides, and the electrolyte is a solution of sulfuric acid.
2. Lithium battery: A type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution.
2. Different lifespan:
1. The lifespan of lithium battery can reach more than 6 years.
2. Lead acid batteries can be used for 10 to 15 years on a float charge.
3. Different battery electrode materials:
1. Lithium metal batteries generally use manganese dioxide as the positive electrode material, lithium metal or its metal alloy as the negative electrode material, and use non-aqueous electrolyte solution battery. Lithium-ion batteries generally useent a lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and a non-aqueous electrolyte.
2. When the lead-acid battery is discharged, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead when charged, the main components of the battery. the positive and negative electrodes are made of lead sulfate.
4. Different characteristics
1. When lead-acid batteries operate normally, electrolyte does not leak from the battery terminals or case. No free acid Special wick separators keep the acid inside and there is no free acid inside the battery, so the battery can be placed anywhere.
2. Lithium batteries have relatively high energy. It has a high storage energy density, reaching 460 to 600 Wh/kg, i.e.approximately 6 to 7 times that of lead batteries.

What is the difference between a lead acid battery and an acid battery lithium?
The difference between lithium batteries and lead acid batteries is: different weight, different lifespan and different battery capacity.
1. The weight is different. The weight of the lithium battery is only 1/4 of that of the lead-acid battery of the same capacity, and the volume is only 1/3 of that of the lead-acid battery. lead acid battery of the same capacity.
2. The lifespan is different. The lifespan of lead-acid batteries is typically around 2 years, while lithium batteries are more durable, with a lifespan of 4-5 years. The cycle of lead acid battery is generally fully charged in 300 times, while lithium battery is fullfully charged and discharged more than 500 times.
3. Battery capacity is different from lead-acid batteries, lithium batteries have higher average operating voltage and higher specific energy. In other words, for the same size rechargeable batteries, lithium batteries. have greater capacity.
Applications of lithium batteries:
Lithium batteries are widely used in energy storage systems such as hydropower, l thermal energy, wind energy and solar power plants. , and uninterrupted postal communications and telecommunications Power supplies, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields.
Lithium-ion batteries have been widely used in portable devices such as laptops, appsareils photo and mobile communications because of their unique performance advantages. Developed high-capacity lithium ion batteries have been tested in electric vehicles and have become one of the main power sources for electric vehicles in the 21st century. They will be used in satellites, aerospace and energy storage.
With the shortage of energy and the pressure of environmental protection in the world. Lithium batteries are widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has promoted the development and application of lithium battery industry.
Different weights, different lifespans, different battery levels and different capacities.
1. His weight is completely different. The weight of the lithium battery is only 1/4 of that of the batlead-acid battery with the same capacity, and the size is also greatly reduced, only 1. /3 of the lead-acid battery. This gives lithium batteries a clear advantage in terms of portability.
2. The lifespan of the two is different. Lead-acid batteries are typically used for around 2 years, while lithium batteries are more durable and can typically be used for 4-5 years.
3. The number of charging cycles of lithium batteries far exceeds that of lead-acid batteries, reaching more than 500 times.
4. From the perspective of battery power, lithium batteries have higher average voltage and higher specific energy, which means that the capacity of lithium batteries is larger under the same volume.
