Amount (7200mAh/cm3), it is nearly three times of traditional carbon negative pole material theoretical capacity, has become the main flow studied in the world and born
One of pole material.When stannum is as lithium ion battery negative material, during the embedding and deintercalation of lithium ion, change in volume is violent,
Material internal can produce stress, and the macro-mechanical performance of stannum itself can not be enough to resist the stress produced therefrom, thus leads
Cause material of main part is broken, efflorescence, so that the efficiency for charge-discharge of electrode is low, cycle performance is very poor.
Graphene has special construction and performance because of it, and its application in lithium ion battery electrode material have also been obtained extensive concern.

There is higher storage lithium ability.Additionally, the high electron mobility (15000cm of material itself2/ (V s)), prominent heat conductivility (3000
W/ (m K)), the mechanical property (stretch modulus 1.01TPa) of good chemical stability and excellence so that it is as combination electrode
The matrix of material has more outstanding advantage.
The developing into of electrostatic spinning technique is prepared new electrode materials and is provided new probability, utilizes electrostatic spinning to prepare and receives
Rice or micron-sized fibrous material.The appearance structure of its uniqueness of nanofiber and specific surface area are applied to lithium ion battery and demonstrate
Big advantage: electrode/electrolyte contact area is big, and the path of electronics and lithium ion conduction is short, output is high；Lithium deintercalation
During bulk effect little, cycle life improve.Therefore, nano-fiber material can significantly improve battery for lithium ion battery
Specific capacity and rate charge-discharge performance.At present, electrostatic spinning and high temperature cabonization technology is utilized to prepare carbon/stannum/Graphene composite Nano
Fiber is also seen for the relevant report of lithium ion battery negative material.
