The laboratory is a joint scientific structure which includes researchers from the Institute of Electrochemistry and Energy Systems and the Institute of General and Inorganic Chemistry at the Bulgarian Academy of Sciences. The laboratory staff performs fundamental and applied research studies using current state-of-the-art methods for electrochemical synthesis, electrochemical testing and characterization of materials for energy storage applications and electrocatalysis. His activity is also focused on physicochemical tests of materials for electrochemical energy storage / conversion systems, mainly for lithium-ion batteries, post-lithium-ion batteries and supercapacitors. Potential partners and clients of the laboratory can be research teams in the country and abroad with similar scientific interests, as well as companies with applied activity in the field.

GLOVE BOX MBRAUN, MB-UNILAB PRO SP (1500/780),

H2O and O2 content < 0.1 ppm.

The equipment enables manipulation and preparation for analysis of moisture-sensitive samples in an argon atmosphere and with controlled levels of moisture and oxygen.

Additional equipment to the dry box is Zeiss Stemi 508 microscope. The microscope gives the opportunity for an instant observation of the condition of the samples, as well as obtaining three-dimensional image.
