The age of lithium batteries has come, and the age of lead-acid will become history

In recent days, several articles of the Ministry of Industry and Information Technology have once again caused a big storm in the battery industry. These articles probably have the same theme, about the recycling and reuse of batteries for new energy vehicles. In addition, on February 15 this year, the new national standards for the lithium battery industry have been implemented, namely the 'Lithium-ion Battery Industry Specification Conditions (2018 Edition)' and the 'Interim Measures for the Administration of Lithium-ion Battery Industry Specification Announcements (2018 Edition)'. This shows that the country is actively supporting the development of lithium batteries.

The purpose of the Ministry of Industry and Information Technology is already very obvious: to guide lithium batteries to replace lead-acid batteries, so that both industrial upgrades and environmental protection are huge Meaning, how likely is it that lithium batteries replace lead-acid batteries? How long can it be achieved?

1. Lithium batteries have great development potential, and lead-acid batteries are approaching their physical limits.

Currently, lead-acid batteries are in technical personnel With our efforts, we have approached the limit of the physical properties of the battery itself. The batteries on the market basically need to be replaced with new ones after 1-1.5 years, and the longest battery life is no more than 3 years. As a new development, lithium batteries have only been developed for 50 years. At this stage, they have a service life of more than 6 years. They have a high storage energy density, reaching 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. The incomparable advantages of acid batteries naturally have unlimited potential.

2. Lead-acid batteries are seriously polluted, and lithium batteries are green.

Pollution is currently the biggest dilemma faced by lead-acid batteries , Lead-acid batteries use lead as the raw material of the plate, and lead itself is a heavy metal pollutant, which is harmful to the human body and the environment. Therefore, the production and recycling of lead-acid batteries have always been a bottleneck restricting their sustainable development. Lithium batteries are green and environmentally friendly. Regardless of production, use or scrap, they do not contain or produce any toxic and harmful heavy metal elements such as lead, mercury, cadmium, etc. Material, this is very consistent with my country's current environmental protection situation.

At present, the two traditional battery giants of Tianneng Chaowei have vigorously put into production of lithium battery projects, and have begun to develop lithium battery products. Domestic lithium battery companies such as CATL and BYD have successively listed in recent years. On the market, traditional lithium battery giants such as Samsung and Tesla made breakthroughs in lithium battery technology with the promotion of new energy vehicles, causing the cost of lithium battery products to begin to drop.

The future of lithium batteries must be a blowout situation. In addition, lead-acid batteries have reached their physical limits, and lithium batteries are still in the research and development period and are still in the market. It is a growth stage, so after the new national standard, lithium battery products are likely to replace lead-acid battery products.
