CCM: Where will waste power Li-ion batteries go 03-09-2016

CATARC predicted that China will have 120,000-170,000 tonnes of waste power Li-ion batteries removed from alternative energy vehicles by 2020. Then, where will these batteries go?



 

China’s alternative energy vehicle industry is booming, but it gradually exposes a problem that the lifespan of power Li-ion battery is relatively short. Although some alternative energy vehicle producers give a 10-year commitment on the lifespan and warranty of their batteries, the average actual life of power Li-ion batteries is only about 5 years, if environmental and other factors are taken into consideration.

 

The China Automotive Technology and Research Centre (CATARC) predicted that China will have 120,000-170,000 tonnes of waste power Li-ion batteries removed from alternative energy vehicles by 2020. Then, where will these batteries go?

 

Theoretically speaking, these waste power Li-ion batteries still have their value, as they can be used on energy storage, power station, road lamps, and low-velocity electric vehicles (EV) before they are finally recycled. This is the so called “reuse” or “cascade-use”.


In Jan. 2016, General Motors Company (GM) announced to publish its technology development plan on the reutilisation of power Li-ion battery. Prior to this, GM once considered about applying the waste batteries to power system, similar to the idea of other insiders.


“The cascade-use of power battery is not only energy-saving, but also cost-saving, if it can be applied widely,” said Yin Chengliang, vice director of the Automobile Engineer Research Institute of Shanghai Jiaotong University.




The Chinese government thought highly of the issue and released some policies to regulate the work of dealing with waste power batteries. For instance, the National Development and Reform Commission, Ministry of Industry and Information Technology (MIIT), Ministry of Environmental Protection jointly released the Technology Policy for the Recycle of Electric Vehicle Power Battery (2015 Edition) in Jan. 2016. Accordingly, EV producers and power battery producers were defined as liabilities for the recycling of power battery, and a coding system for power battery was established. Besides, power battery dismantled from vehicles must be cascade-used first before being recycled. The MIIT also released the Industry Regulations on the Integrated Use of the Waste Power Battery from Alternative Energy Vehicles (Exposure Draft) and the Interim Measures for the Industry Regulations on the Integrated Use of the Waste Power Battery from Alternative Energy Vehicles (Exposure Draft).


Currently the subsidiary of State Grid Corporation of China in Beijing and Zhejiang are dedicated to research on the use of the complementary energy of power Li-ion battery. They already invested in the research project of cascade-use of power Li-ion battery, but the process is rather slow, according to an analyst in the alternative energy industry.


In fact, it is not easy to reuse the waste power Li-ion battery in energy storage on a large scale. Although storage Li-ion battery has a lower demand for battery cell density than power Li-ion battery, the scale of a storage project usually reach 100 KWh or even 10,000 KWh, indicating that a large amount of alternative energy vehicle power Li-ion batteries (average capacity of about 30 KWh each) are needed to make a battery pack. This will result in low uniformity in battery pack and hard to be managed, so the overall effect of storage cannot be guaranteed.


Moreover, the battery circuit, size and evaluation requirements in China vary from vehicle enterprise to vehicle enterprise, leading to scattered types of batteries, so it is more difficult for cascade-use.


Therefore, the cascade-use of power Li-ion battery may only be applied on a small scale, such as in household energy storage programs.
