Project summary

Lithium containing wastes are characterized by a number of specific properties requiring special approaches when making decisions regarding their utilization. In particular, during lithium current sources production the output of rejected lithium current sources is rather large, that’s why there is a problem of there utilization. Rejected lithium current sources are subject to their disposal with observance of a series of obligatory requirements. Many chemical components of lithium current sources are hazardous and toxic. Depressurization of lithium current sources and probable emission of lithium into the environment will result in negative ecological consequences. First of all it’s connected with lithium fire- and explosion hazard. Lithium is characterized by extremely good reactivity and reacts with a number of substances with great heat release. Interaction of lithium even with water traces results in hydrogen release, hydrogen mixtures with air are dangerously explosive. Aproton dipolar solvents (propylene carbonate, butyl lactones, dimethyl sulfoxide, dimethylamides, etc.) are used in lithium current sources as electrolytes. Organic matters are characterized by long-term influence on human body which hasn’t been studied completely and they can cause great irreversible ecological damage to the environment. Thus, expediency of rejected lithium current sources utilization is obvious.

Preliminary tests regarding lithium containing wastes have been carried out by author group. Research group has experience in the development of the catalysts and reactors for combustion of flamable and explosive gases.

The following tasks are planned to be solved in the process of performance of expected project:

· mechanical opening of lithium current sources;
· treatment of the received scrap with reagents to “extinguish” lithium metal;
· safety catalytic combustion of releasing hydrogen in the presence of organic compounds vapors;
· treatment lithium-containing mixture for the separation of inorganic and organic components;
· regeneration of lithium and catalytic combustion of organic components of the mixture.

Implementation of the given Project makes it possible to solve the problem of discharging the wastes non-hazardous to environment, to reorient the scientific and technical personnel specialized in the field of radioactive materials reprocessing to peaceful production, to ensure employment of high-qualified specialists (that can lose their work because of reduction of main stream production volume) in the field of solving the environment protection tasks, as well as to favour the conversion of enterprises of defense complex to market economy meeting civil needs.

Funding of the present Project will provide for the support of the applied R&D works for peaceful purposes.

Potential role of foreign collaborators:

Contacts with foreign firms are suggested to be established with the aim of mutual consultations, visits, joint patenting of technology and production of plants for utilization of lithium containing wastes.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
