The annual volume of this forestry waste is about onemillion tons per year only in Siberia. The major part of pine nutshell is not processed,similar to apricot nutshell. Recently, it was reported that Kazakhstan and Japanscientists have developed in cooperation a method of apricot nutshell carbonization.Using this method, it is possible to produce carbon anodes for lithium-ionaccumulators with improved (3-5 times) characteristics in comparison with thegraphite ones. In literature, there is a set of criteria of a «good» carbon anode. Oneof them correlates with the surface area of a carbon but does not correlate with eitherinterplanar distance or graphitization degree and has weak particle sizedependence [1].Nanostructured carbon materials have the highest surface area. One of suchmaterials is КEMERIT ® [2].The use of Siberian pine nutshell as a raw material in producing carbons likeКEMERIT ® resulted in the synthesis of a nanostructured carbon material with highsurface area (up to 3500 m 2 /g) and high pore volume (up to 1.7 cm 3 /g). Is it possibleto use this carbon for production of lithium-ion accumulator anodes? To answer thisquestion, the development testing must be done. Both a standard test bench and aninterested customer are requirements for carrying out such testing.References:[1]. I.A. Kedrenskiy, V.G.
