Advantages of lithium-ion battery electric vehicles:
1. Lithium-ion batteries have a long lifespan, are lightweight, and are small in size.
Lithium-ion battery electric bicycles have similar power performance to lead-acid battery (basic electric bicycles). They can be charged in 6 to 8 hours and can travel 30 to 45 kilometers depending on the battery capacity. They weigh only about 1/5 of lead-acid batteries. The biggest advantage of lithium-ion battery electric bicycles is their long lifespan.
Disclaimer: Those who say lithium-ion batteries are expensive are only seeing the surface. In fact, if you calculate carefully, the cost is about the same as that of lead-acid batteries. Currently, lithium-ion batteries generally have a 2-year warranty, while lead-acid batteries have a 1-year warranty.
2. Lithium-ion batteries have activation-free characteristics.
It's important to note that lithium-ion batteries enter a dormant state after being stored for a period of time, at which point their capacity is lower than normal, and their usage time is shortened. However, lithium-ion batteries are easily activated; they can be activated and restored to normal capacity after just 35 normal charge-discharge cycles. Due to the inherent characteristics of lithium-ion batteries, they have virtually no memory effect. Therefore, users do not need special methods or equipment to activate new lithium-ion batteries.
3. Memoryless effect
Consumers have always worried about the memory effect when charging lead-acid and nickel batteries. However, with lithium-ion batteries, everyone can breathe a sigh of relief, as lithium-ion batteries do not have a memory effect. If some consumers are still unsure how to charge lithium-ion batteries, please read the following information.
Disadvantages of lithium-ion battery electric vehicles:
1. The high price of lithium-ion battery electric vehicles is due to lithium-ion batteries.
Currently, lithium-ion battery electric bicycles are generally several hundred to a thousand yuan more expensive than lead-acid battery electric bicycles, making them difficult for consumers to accept in the market. Lithium-ion batteries are lightweight, environmentally friendly, and do not cause pollution after disposal. Once the application technology matures and market sales increase, the price of lithium-ion battery electric bicycles will likely decrease.
2. Overcharging lithium-ion batteries can be counterproductive.
Lithium-ion batteries and chargers automatically stop charging once the battery is fully charged; there is no trickle charging for over 10 hours as claimed by nickel-cadmium chargers. In other words, leaving your lithium-ion battery on the charger after it's fully charged is pointless. Furthermore, no one can guarantee that the battery's charge/discharge protection circuitry will never change or that its quality will be flawless, so your battery will be constantly teetering on the edge of danger. This is another reason why we oppose prolonged charging.
Furthermore, in some electric vehicles, if the charger is not removed after a certain charging time, the system will not only fail to stop charging but will also begin a discharge-charge cycle. While the manufacturer may have its reasons for this practice, it is clearly detrimental to battery life. Therefore, after purchasing a lithium-ion battery electric vehicle, it is essential to consult the company or dealer for proper lithium-ion battery maintenance.
3. The power performance of lithium-ion batteries needs to be improved.
Lithium-ion batteries are much less resistant to fluctuations in charge and discharge compared to lead-acid batteries. This is one of the main reasons why lithium batteries cannot be effectively used in high-power vehicles, leading to reduced durability.
4. Lithium-ion batteries have prominent safety issues.
The safety of lithium-ion batteries still needs improvement. The risk of fire, combustion, and even explosion cannot be completely eliminated at present. Vehicle collisions can cause the battery's positive and negative electrode materials to rupture the separator. The instantaneous extremely high current during braking, when energy rapidly recharges into the battery, can also lead to short circuits, increased temperature, and potentially combustion or even explosion. The fire is caused by collisions or short circuits leading to lithium ion release, which ignites upon contact with air. Furthermore, the electrolyte in lithium-ion batteries is an organic electrolyte, which is more prone to ignition and combustion upon contact with air.
