The particular work shows a new strategy to improving the performance of lithium power sources by using polypeptides since an active component associated with the cathode composition. Particularly, the experimental results of assessment prototypes of lithium current sources with cathodes based on polypeptides, which show the value of the particular specific discharge capacity at the level of 2000–2700 mAh/g, depending on the content of the natural component, are presented. The use of the intermittent galvanostatic titration mode during the discharge showed an increase in the specific indicators of the current sources when compared with the continuous discharge on different specific load currents. Based on this, the effect of “relaxation recovery” of the cathode materials based on polypeptides has been discovered, the essence which is a significant increase (recovery) of the open-circuit volt quality when the load of the particular lithium current source is disconnected, which leads to an increase of the release capacity without external energy influences. The functionalization from the surface of thermally extended graphite with polypeptide elements made it possible to create a cathode material, the use of which in lithium current source models increased the specific discharge capacity to 19, 000 mA h/g on a discharge current associated with 10 mA/h.
