Common additives include film forming additives, conductive additives, flame retardant additives, overcharge protection additives, additives to control the content of H2O and HF in the electrolyte, additives to improve low temperature performance, multifunctional additives, etc. There are many kinds of additives, different uses, but also PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC is the core competitiveness of electrolyte production enterprises,
Commonly used additives are FEC and VC. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC for iron removal: 1.0M LiPF6 in EC:DMC=1:1 Wt%, 1.0M LiPF6 in EC:DMC:DEC= 1:1:1:1 Vol%, 1.0M LiPF6 in EC:DEC:EMC= 1:1:1:1 Vol%, 1.0M LiPF6 in EC:DEC=1:1 Vol% with 5.0% FEC, etc. Lithium-ion battery electrolyte should meet the following basic requirements:
During the cycle, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC can maintain good electrode and electrolyte interface when the volume of the electrode material changes. High ionic conductivity, generally should be more than 10-4 S/cm; Low electronic conductivity, generally should be less than 10-10 S/cm; High thermal stability, in a wide range of temperature (-40℃ - 60℃) does not occur decomposition; Good chemical stability, in a wide range of voltage to maintain the stability of electrochemical performance; Good compatibility with other parts of the battery such as electrode material, electrode collector fluid and diaphragm; Safe, non-toxic and pollution-free.
