Electric vehicle batteries are the power source for electric vehicles. The batteries that can be used by electric bicycles include valve-regulated lead-acid maintenance-free batteries, colloidal lead-acid batteries, nickel-metal hydride batteries, and lithium-ion batteries. Compared with lead-acid batteries, lithium-ion batteries have stronger durability and better vibration resistance. The fully charged battery is safe and fixed, consumes slowly, has been charged and discharged more than 500 times, and has no memory. The general life span is 4-5 years. . Lead-acid batteries are generally within 400 times of deep charge and deep discharge, have memory and have a lifespan of about two years. If a maintenance-free lead-acid battery is used, it should be noted that the battery loses less water and generally does not need to add distilled water during use. Of course, their differences are not only reflected in these aspects.

    In terms of price: Because lithium batteries have better heat dissipation and battery life, the production process from packaging to sealing is also very strict; therefore, the production cost is much higher than that of lead-acid batteries.

    The battery materials are different: in the working state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; when it is charged, the main component of the positive and negative electrodes is lead sulfate.

    In the working state of the lithium battery, the main component of the positive electrode is manganese dioxide, and the main component of the negative electrode is lithium metal or its synthetic metal, and a battery uses a non-aqueous electrolyte solution; in the charged state, the positive electrode material of the lithium-ion battery usually uses lithium Alloy metal oxide, the anode material is graphite, and the battery uses a non-aqueous electrolyte.

    Environmental protection degree: Under the environmental protection policy, in order to ensure that the environment can reduce pollution, there is pollution caused by improper handling in the production, use and recycling of lead-acid batteries, while lithium batteries are due to their own packaging and sealing work. Relatively perfect, it will be relatively environmentally friendly.
