Synthesis and study of carbon nanostructured additives for lithium-ion batteries

Abstract

High rates of specific capacity are a key characteristic of lithium-ion batteries compared with conventional nickelcadmium, nickel-metal hydride and lead-acid battery systems. Currently, lithium-ion batteries are ane of the most widely used
power sources in military, medical, consumer and industrial electronic devices. Despite the high specific indicators, a number
of applications require the achievement of even higher characteristics, since lack of energy leads to a decrease in the period
of operation of devices between the moments of battery charging. The solution of this problem is connected both with the
development of new materials and with the optimization of the microstructure of the electrodes. In this regard, this work was
devoted to studying the effect of synthesized and modified nanostructured carbon additives on the functional characteristics of

the positive electrode based on lithium iron phosphate for lithium-ion batteries. Studies have shown that the use of modified
carbon nanotubes by Hammers method instead of commercial carbon nanotubes significantly increases the specific characteristics
of lithium-ion batteries.
