Technical full analysis: why lithium ion battery explosion is constantly

The latest news shows that before and after 2020, my country's powered lithium battery accumulated scrap volume will reach 120,000 --17 million tons. Therefore, before the peak of scrap, the construction and development of regulations, technologies, etc., which have important significance for the healthy development of new energy vehicles in the future.

my country's new energy vehicles enter sales rapidly after 2013, and most of the power lithium batteries in the market have not yet entered the scrap period. However, with the development of new energy vehicles, the demand and dramatic volume of vehicle power lithium batteries will increase. For the company, the power lithium battery recycling has huge business opportunities.

After recycling, it can save battery manufacturers to save raw material costs. In addition, power lithium battery recovery is closely related to government building low-carbon economy and environmentally friendly society. Waste dynamic lithium batteries have become a serious threat to the industry's estimated industry, the waste power storage battery recycling market will begin to outbreak in 2018, which can reach 5 billion yuan; to 2020 and 2023, the scale of waste power storage battery will further increase to 136 100 million yuan and 31.

1 billion yuan. Combined with factors such as car scrap years and dynamic lithium battery life, the electric vehicle power lithium battery newspaper was predicted, and the annual report of powerful lithium battery for electric vehicles in my country in 2025 or can reach 350,000 tons. Potential threat of waste dynamic lithium batteries on the environment and human health.

The existing waste battery handling method is highly cured deeply, stored in waste mines and resource recovery, but the current capacity of my country's battery resource recovery is limited, most of the waste batteries do not have a valid disposition, will give natural environment and humans. Health brings potential threat. Although the power lithium battery does not contain mercury, cadmium, lead and other heavy metal elements, but also bring environmental pollution.

For example, once its electrode material enters the environment, the metal ions of the battery positive electrode, the carbon dust, the strong base and heavy metal ions in the electrolyte may cause weight, including the pH of the soil, and may appear. Poisonous gas. Power lithium battery recovery, the Broken National Grant Securities announced the "Dynamic Lithium Ion Battery Recycling Industry Research Report" pointed out that my country's dynamic lithium battery recovery technology is more mature, and has strong technical capabilities, high environmental protection, high-level nickel-hydrogen Battery, lithium-ion battery recycling company.

But management is relatively backward, hindering the development of the power lithium battery recovery industry. Important performance: The recycling network is not perfect, the recycling network is important by the small and medium-sized recycling company, it is difficult to obtain effective recycling; the recycling company is small, the process level is not sound, it is difficult to ensure resource recovery efficiency; there is no business license company illegally engaged in waste Power lithium battery recycling, with safety and environmental hidden dangers. By management, the dynamic lithium battery recovery pain points are obvious, reflected in four aspects: market chaos, inferior currency deports ", channel problems, system is critical; market treatment, it is difficult to have scale effect; waste battery is higher than Purchasing new battery.

What is the way? The above report believes that despite the existence of resistance, my country clearly adopts the manufacturer's responsibility extension system, with the continuous improvement of the policy, the industry is gradually going to standardize. As new energy vehicles continue to rise, the recycling problem of electric vehicle power lithium-ion batteries will be more and more prominent, and the national and local governments have issued policies to accelerate the construction of benign industrial ecosystems. The stone of the mountains can be attacked Japan: Japan is a better country in the recycling of waste batteries.

Since October 1994, Japanese battery production and sales vendors began to form "battery production and sales - recycling - regenerative treatment" battery recycling system, battery retailers, automotive vendors and gas stations can be free from consumers Recycling waste battery. EU: Since 1990, Europe's cars have begun to emphasize the reuse of materials and components in automobiles. EU 2006/66 / EC battery instructions are directly related to battery recycling, which involves all kinds of batteries, and requires automotive battery manufacturers to establish automobile waste battery recycling systems.

The EU has enforced waste batteries since 2008, and the recovery fee is burden by manufacturer. United States: The United States has set up multiple laws from federation, state to place, using licensed management methods to strengthen supervision of battery production companies and waste battery resources recycling. The US International Battery Association has developed a deposit system to promote consumers to actively pay the old battery.

At the same time, the US government also promotes the additional ambient fees, and the consumer is charged a certain amount of handling fee and the battery production company to pay a part of the recovery fee. As a fund support for battery products, it guarantees the waste battery to a certain extent. Recycling company's profit.
