1. Large capacity
Has a larger capacity than ordinary batteries.
2. Environmental protection
The battery is generally considered to be free of any heavy metals and rare metals, non-toxic, non-polluting, in line with European RoHS regulations, and is an absolute green battery certificate. Therefore, the reason why lithium batteries are favored by the industry is mainly due to environmental protection considerations. Therefore, the battery has been included in the "863" national high-tech development plan during the "Tenth Five-Year Plan" period and has become a key national support and encouragement project.
With China's entry into the WTO, China's export of electric bicycles will increase rapidly, and electric bicycles entering Europe and the United States have been required to be equipped with pollution-free batteries.
3. Improvement of safety performance
The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and generate heat like lithium cobalt oxide or form strong oxidizing substances, so it has good safety.
A report pointed out that in actual operation, a small part of samples were found to burn in acupuncture or short-circuit experiments, but there was no explosion. In the overcharge experiment, high voltage charging that was several times higher than the self-discharge voltage was used, and it was found that there were still Explosion phenomenon. Nevertheless, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium cobalt oxide batteries.
