Most people will definitely be more concerned about the price and the most important component of electric vehicles, the battery, before purchasing a car. There are only two types of batteries on the market: lead-acid batteries and lithium-ion batteries, which greatly determine the overall price. Lead acid batteries are cheap while lithium-ion batteries are expensive, which makes many consumers hesitate to choose lead-acid batteries.

At present, there are various battery brands, styles, and brands selling electric vehicles, with lead-acid batteries and lithium-ion batteries occupying the dominant position. Below, the editor will make a comparison to help you better understand the relationship and differences between these two.

Normally, lead-acid battery packs weigh between 16-30 kilograms and have a larger volume; lithium-ion batteries generally weigh between 2.5-3.0 kilograms and have a relatively small volume, making them easy to ride and transport. From a quality perspective, it is difficult to determine the quality of the two, but consumers can purchase high-quality batteries produced by legitimate manufacturers according to their actual needs.

The cost of main materials such as positive electrode materials, negative electrode materials, current collectors, separators, electrolytes, etc. in lithium-ion batteries is much higher than that of lead-acid batteries. The cost of assembly accessories and external circuit systems for lead-acid batteries is extremely low.

Due to the manufacturing process, the labor cost of lithium-ion batteries is relatively high. In the manufacturing cost, the labor cost of lithium-ion batteries accounts for over 40%, while the labor cost of lead-acid batteries is generally 10% to 20%.

The mechanical equipment used in the production of lithium-ion batteries is expensive and of high value, resulting in significant depreciation losses. Most processes in the production of lithium-ion batteries are irreversible, while lead-acid batteries are reversible for repair and reuse. The recycling value of lead-acid batteries after use is over 40%, while the recycling value of lithium-ion batteries is almost zero.

lithium-ion batteries have a specific energy ratio of more than three times higher than lead-acid batteries, both in terms of volume and weight. lithium-ion batteries are smaller in size and lighter in weight. Long cycle life. The cycle life of lithium-ion batteries used in electric vehicles is generally over 800 times, and lithium-ion batteries using lithium iron phosphate cathode materials can reach about 2000 times, which is 1.5 to 5 times more than lead-acid batteries. This greatly reduces the cost of using lithium-ion batteries, extends their lifespan, and improves their convenience of use. Has a wide range of charging efficiency. This is a unique advantage of lithium-ion batteries. When needed, the charging time can be controlled within 20 minutes to 1 hour, and the charging efficiency can reach over 84%. On the basis of further technological innovation, this feature will be better utilized.

We understand that energy storage products generally need to be evaluated from the perspectives of weight energy density, volume energy density, service life, price, applicability, national policies, etc

Weight energy density

At present, the energy density of lithium-ion batteries is generally between 200-260wh/g, and lead-acid is generally between 50-70wh/g. Therefore, the weight energy density of lithium-ion batteries is 3-5 times that of lead-acid, which means that under the same capacity, lead-acid batteries are 3-5 times that of lithium-ion batteries. Therefore, in terms of lightweight energy storage devices, lithium-ion batteries have an absolute advantage.

Volumetric energy density

The volume capacity density of lithium-ion batteries is usually about 1.5 times that of lead-acid batteries, so under the same capacity, lithium-ion batteries are about 30% smaller in volume than lead-acid batteries.

Usage cycle

The currently popular material systems are ternary and iron lithium. The cycle times of ternary power type lithium-ion batteries are usually more than 1000 times, the cycle times of iron phosphate lithium-ion batteries are more than 2000 times, and the cycle times of lead-acid batteries are usually only about 300-350 times. Therefore, the service life of lithium-ion batteries is about 3-6 times that of lead-acid batteries.

price

At present, lithium-ion batteries are about three times more expensive than lead-acid batteries in terms of price. However, based on the analysis of their service life, if the same cost is invested, the service life of lithium-ion batteries is still longer.

Applicability

lithium-ion batteries have slightly lower safety compared to lead-acid batteries, so various safety precautions should be taken during use, such as preventing external forces or accidents from damaging the lithium-ion battery, as this may cause fire or explosion; At present, the temperature applicability of lithium-ion batteries is also very good, so in other adaptability aspects, lithium-ion batteries are no less than lead-acid batteries.

National policy

Lead acid batteries pose significant environmental hazards due to production processes or discarded batteries. Therefore, from a national policy perspective, restrictions have been placed on the expansion and reinvestment of lead-acid batteries, or on their use in certain fields. In the future, the trend of replacing lead-acid batteries with lithium-ion batteries will become increasingly apparent, and the progress will gradually accelerate.

How to correctly distinguish between lead-acid batteries and lithium-ion batteries

● In terms of battery capacity

The capacity of lithium-ion batteries is generally 8-10 amperes, while lead-acid batteries have a capacity of around 20 amperes.

● In terms of driving kilometers

For example, with the same 48V battery, both lithium-ion and lead-acid electric vehicles can travel 30-40 kilometers when fully charged, and their speed depends on the size of the motor used.

● In terms of durability

lithium-ion batteries have strong durability, slow consumption, over 500 charging and discharging cycles, and no memory, with a general lifespan of 45 years. Lead acid batteries generally have memory and a lifespan of about two years, with deep charging and discharging up to 400 times. If a maintenance free lead-acid battery is used, it should be noted that the battery has a low water loss, and distilled water is generally not needed during use. In terms of durability, lithium-ion batteries have good vibration resistance. The fully charged battery is securely fixed and vibrates for 1 hour at a frequency of 16.7Hz with a 4mm amplitude. There is no leakage, expansion or rupture of the battery, and the open circuit voltage is normal; Good overcharging resistance, 25 degrees Celsius, fully charged battery with 0.1CA charge for 48 hours, no leakage, no battery expansion or rupture, normal open circuit voltage, capacity maintenance rate above 95%; Good resistance to high current, fully charged battery with 2CA discharge for 5 minutes or 10CA discharge for 5 seconds, no conductive parts melted, and no appearance deformation.

In terms of price and warranty period

The current mainstream battery in the market is 48 volts. If it needs to be replaced, lead-acid batteries cost around 380-450 yuan (48V12AH-48V20AH) with a warranty period of 1 year; lithium-ion batteries are relatively expensive, costing around 1000 (48V12AH) yuan, but their warranty period is 2 years.
