Nowadays, the output of coal and carbon products in
China accounts for a high ratio in the global production.
However, the overproduction is becoming to be one of the
pressing issues. Therefore, the problem of deriving addi-
tional value to carbon products such as CB, has become
topical in China. For more than two decades, lithium-ion
batteries have gradually been becoming the ideal current
source for electrical products and high-energy battery
of automobiles. The development of lithium-ion battery
industry is one of the most important studies carried out
around the world. In particular, fabrication of high-power
electrode materials has been developed remarkably in
various groups [1–8]. Hence, extending the usage of CB
in fabrication of electrodes of lithium-ion batteries is one
of the possible ways to solve the overproduction problem.
Generally, the CB and acetylene black are usually used
as conductive materials in fabrication of carbon electrode
materials for lithium-ion batteries. The reports of CB for
charge-discharge of lithium-ion batteries are really poor.
In our study we considered CB having big speciﬁ c surface
area and attempted to explore the lithium-ion charge-
discharge capacity of CB to expand its application on
the lithium-ion batteries. However, in the CB production
processes, many hydroxy and carboxyl groups formed on
the surfaces of CB, which results in the CB with strong
hydrophilicity, leading to the decrease in the lithium-
ion charge-discharge capability. Therefore, decreasing
the hydrophilicity of CB surface becomes important in
researching CB as carbon anode materials.
Recently, producing composite materials of carbon
with 14 group metals having high electrochemical
performance were widely reported in the world [9–11].
Especially, the C–Si composite materials were extremely
attracted attention for fabrication of electrode materials

Abstract—Carbon black (CB) was simply modiﬁ ed by tert-butylchlorodimethylsilane (TBDMCl) to form the
–C–OSiR and –C–OOSiR structures on the surface of CB. The formation of –C–OSiR and –C–OOSiR structures
on CB was veriﬁ ed by FTIR and XRD measurements. The modiﬁ ed carbon black (MCB) has relative high elec-
trochemical performance, which was determined by electrochemical studies. The ﬁ rst charging capacity of MCB
is at 343 mAh g
and the conductivity of MCB is at 148.1 Sm
which is similar to that of CB 155.2 Sm
results indicate that application of the obtained MCB will be promising for lithium anode materials. Meanwhile,
these results can also suggest solving the overproduction problem of CB in China.
