In recent years, with the improvement of my country's awareness of environmental protection issues and the advancement of technology, the development of electric bicycles has become more and more popular among the public. However, many information users can find that compared to our previous lead-acid batteries, the current electric bicycle lead-acid batteries seem to be less durable, and both battery life and lifespan have dropped significantly. Among them, the ban on cadmium is a very important reason. This study will start from this need and analyze the reasons for the decline in durability of electric bicycle lead-acid batteries.

1. Ban on cadmium element

In the past, cadmium was often added to lead-acid batteries to improve their performance. The addition of cadmium can improve the conductivity of the battery and inhibit the self-discharge of the battery, thereby extending the life of the battery and improving the durability of the battery.

However, cadmium is a toxic substance that threatens the environment and human health. Therefore, with the strengthening of environmental protection policies, the use of cadmium in lead-acid batteries is gradually banned.

2. Battery performance decreases

Battery life can be reduced: In cadmium-free lead-acid batteries, due to the lack of cadmium's inhibitory effect, the self-discharge phenomenon inside the battery will increase. This causes the battery to lose power faster during the storage process, thereby increasing the battery's endurance and causing it to continue to decline.

Short life: Cadmium not only improves the conductivity of the battery, but also increases the strength and corrosion resistance of the panel. Banning cadmium would reduce the strength and corrosion resistance of panels, making them more susceptible to damage and shortening their lifespan.

3. Technological progress and market demand

Although the durability of cadmium-free lead-acid batteries has been affected, with the advancement of information technology, some new lead-acid batteries are gradually being developed to replace traditional lead-acid batteries. These new power battery management studies are not only more environmentally friendly, but also improve performance and lifespan.

In addition, as the market demand for electric bicycles continues to increase, the performance and environmental protection requirements for batteries are also getting higher and higher. This further promotes the research and development of battery technology.

4. How to deal with battery durability issues

Improve information technology: and research institutions should strengthen the research and development of new lead-acid batteries. Through the development and progress of network technology, the performance loss caused by the ban of cadmium elements can be compensated.

User education: Teach users the correct use and maintenance of batteries to extend battery life. For example, avoid deep battery discharge and perform regular battery maintenance.

Establish a recycling mechanism: Establish a complete battery recycling and disposal mechanism to reduce the impact of used batteries on the environment and promote resource reuse.

In general, the decline in durability of electric bicycle lead-acid batteries is closely related to the ban on cadmium. But that doesn’t mean we don’t have a choice ourselves. Through the development and progress of information technology, user management education and the establishment of recycling mechanisms, our country can still enjoy the convenience brought by electric bicycles while protecting the ecological environment.
