In what may seem like a supervisor, China now calls on its citizens to trade in electric bicycles based on lithium -ion battery for newer models with sealant lead batteries (SLAs).

Electric bikes are an extremely popular form of travel in urban areas in China. It is estimated that 350 million electric wheels from different forms of roads and bicycle routes in China are estimated.

Most electronic bikes in China are more like what we call a scooter or motorcycle, and many families as well as young adults rely on these electronic bicycles for daily transportation. While technically require pedal and maximum speed of 25 km / h (15.5 mph) to be eligible as an electronic bike in China, most users eliminate pedal and effectively work as a scooter.

SLA batteries, usually in the form of absorbed glass mattress SLAs (AGM), are usually used in electric bikes in China for decades. In fact, lead acid batteries technology is over 100 years old, and the early electric cars sold in the early 1900s used lead acid batteries.

Over the past decade, China is witnessing the change in old, heavy and bulky batteries to lighter and lasting lithium -ion batteries.

However, safety concerns about rare lithium batteries at the same time have created a pause. The government established New safety standards Last year for lithium -ion batteries on electronic bicycles, but there is also a large return to AGM batteries for the domestic market. Even the main technology leaders in the industry, such as Yadea and NIU, produce many AGM -based electronic bikes for the domestic market, while first exporting electronic bicycles of lithium -ion battery abroad.

We are witnessing the Chinese Ministry of Commerce (MOC) now Announcing new policies To promote more lithium -ion battery businesses, electronic bikes for AGM models. The new MOC policy includes subsidies to help people buy new models.

The traded electronic bikes are sent to eliminate and recycled, the move MOC says to help the old electric bike phase is intended with safety risks.

While lead -based seal -based batteries have a higher safety margin, they have significantly lower energy and life density. To help solve this issue, some companies, Like yadeaPressure for sodium ion batteries to replace lead and lithium -ion batteries as a large chemistry of the next electronic bike battery.

Sodium ion batteries have the safety benefits of lead acid batteries, but offer a better energy and longevity density that begins to approach lithium ion batteries. This cost is relatively high for new battery technology, but it is expected to help reduce costs in the next few years.
