1. Lead-acid battery
Advantages: stable voltage, cheap price, simple maintenance, stable quality, and high reliability.
Disadvantages: short cycle life (low life): the theoretical cycle number is about 1/3 of that of lithium-ion batteries, and there is a risk of lead pollution in the industrial chain: there is a risk of lead pollution in the entire industrial chain.
2. Lithium battery
Advantages: Lithium battery has long life, lightweight and small size. The power performance of lithium battery electric bicycles is similar to that of lead-acid batteries. It can run for 30-45 kilometers according to the battery capacity after charging for 6-8 hours. After that, the attenuation is serious, and the user needs to maintain and replace the battery regularly. Under normal use intensity, lithium batteries are basically maintenance-free within three years. The biggest advantage of lithium-battery electric bicycles is their lifespan.
Disadvantages: The price of electric vehicles is too high, but it may save money in the long run (battery money), and the power performance needs to be improved.
3. Graphene battery
The development of lithium batteries has already become a bottleneck, but people's desires and the market will not wait for the breakthrough of lithium batteries, and the combination of lithium batteries and graphene materials has completed a technological breakthrough.
Advantages: The storage capacity is three times that of the best lithium battery, and the charging is fast. Long service life, its service life is twice that of lithium batteries. These advantages are also reflected in the price. The average price of lithium batteries is around 2000, while that of graphene is around 3000.
Disadvantages: In a word, expensive, which can be seen from the price. As the country pays more and more attention to environmental protection, electric vehicle batteries will gradually be replaced by lithium batteries and graphene batteries in the future.
4. Ni-MH battery
Because there are still relatively few companies using nickel-metal hydride batteries as electric vehicle batteries in the market, so I won't go into details.
5. Nickel-cadmium battery
The most fatal disadvantage of nickel-cadmium batteries is that if they are not handled properly during charging and discharging, there will be serious memory effects, which will greatly shorten the battery life, and they have now been eliminated by the electric vehicle industry.
All in all, the battery can be said to be the most important accessory of an electric vehicle, which directly affects the service life. Simply put, if you want power, choose a lead-acid battery, and if you want to use it for a long time, use a lithium battery or a graphene battery.
