For lithium ion batteries, the cathode materials that can be used should meet the characteristics of large reversible capacity, high potential and stability, non-toxic and low production cost. At present, lithium iron phosphate is the most common cathode material for lithium ion batteries. However, LiFePO4 has poor electrical conductivity and low lithium ion mobility. If LiFePO4 material is combin...

Graphene Oxide is a two-dimensional planar nanomaterial composed of carbon atoms with a hexagonal honeycomb lattice，the c-c bond length is 0.141nm, the theoretical density is about 0.77mg/m2, and the thickness is only about the diameter of a carbon atom. Carbon atoms participate in hybridization in the way of sp2, and electrons can smoothly conduct between layers, so graphene conducts electricity ...

Professor GOODENOUGH, the father of lithium battery, has made a great contribution to the research of ...

Graphene anode material has the potential to replace graphite material as a new cathode material for lithium ion batteries due to its unique two-dimensional structure, excellent electron transport capacity and super large specific surface area. The lithium storage mechanism of graphene anode material is similar to that of other carbonaceous materials. During charging, lithium ions come out from th...

Lithium cobalt oxide battery is composed of cobalt oxide cathode and graphite carbon anode. The LCO cathode has layered structure, during discharge, lithium ions move from anode to cathode, with the flow reversing when the battery is charging. Its high specific energy makes lithium cobalt oxide battery a popular choice for mobile phones, laptops and digital cameras. The disadvantages of lithium co...

One of the most successful lithium ion systems is the cathode combination of nickel-manganese-Cobalt (NMC). Like lithium manganate, the system can be customised for use as an energy or power battery. For example, the NMC in the 18650 battery under moderate load has a capacity of about 2,800mAh and can provide 4A to 5A discharge currents. The same type of NMC, optimized for a specific power, has a ...

Lithium phosphatehas good electrochemical performance and low resistance. This is achieved through nanoscale phosphate cathode materials. The main advantages are high rated current and long cycle life; Good thermal stability, enhanced security and tolerance to abuse. If kept at a high voltage for a long period of time, lithium phosphate is more tolerant to full charging conditions and is less stre...

NCA cathode materials batteries have high specific energy, good specific power and long service life similar to NMC cathode battery.
