How to dispose of used Li-ion batteries in Mongolia?

But the preferred option for used Li-ion batteries is recycling or disposal. In Mongolia, Li-ion batteries are classified as hazardous. As appropriate recycling facilities are not available in many developing countries, battery suppliers tend to be responsible for the recycling or disposal of battery cells.

How does Mongolia's Bess work?

Ulaanbaatar. To ensure the charging of clean energy only, the energy capacity of Mongolia’s BESS is matched to the total amount of electricity from renewable energy plants, mainly wind farms, that would have otherwise been curtailed.

Are Li-ion batteries a good choice for grid energy storage?

Li-ion batteries are considered the most beneficial choice in terms of both technology and economy for utility-scale grid energy storage. They are often selected for grid stabilization purposes because they provide ancillary services. The characteristics of the Li-ion technology have made it well-suited

What are the challenges faced by the government of Mongolia?

The Government of Mongolia has encountered challenges that include (i) selecting the right battery technology and optimally sizing the BESS to ensure clean energy charging, (ii) determining BESS ownership, (iii) appropriate charging and discharging tarif levels, (iv) BESS safety regulations, and (v) the handling of used battery cells.

How to manage battery operational risks in developing countries?

Battery operational risks, such as the risk of fire or of shortened battery life, need to be mitigated during the BESS design stage and during the operational stage. Well-trained domestic BESS operators and a well-organized O&M strategy are key to sustainable BESS operations in developing countries.

Which battery technology is best for utility-scale grid storage?

In the current market, lithium-ion (Li-ion) batteries are the dominant technology for utility-scale grid storage, while other technologies, such as NaS batteries and redox flow batteries, also have proven track records in the market.
