Disadvantages:

When carbon nanotubes are directly used as negative electrode materials for lithium-ion batteries, there are problems such as high irreversible capacity, voltage hysteresis, and unclear discharge platform. Single walled carbon nanotubes, such as Ng, were prepared using simple filtration and directly used as negative electrode materials. Their initial discharge capacity was 1700mAh/g, and their reversible capacity was only 400mAh/g.

Another application of carbon nanotubes in negative electrodes is to composite with other negative electrode materials (graphite, lithium titanate, tin based, silicon based, etc.), utilizing their unique hollow structure, high conductivity, and large specific surface area as carriers to improve the electrical properties of other negative electrode materials.

5. Lithium rich manganese based cathode material

High capacity is one of the development directions for lithium-ion batteries, but the energy density of lithium iron phosphate and nickel cobalt manganese oxide in current positive electrode materials is 580Wh/kg and 750Wh/kg, both of which are relatively low. The theoretical energy density of lithium rich manganese based materials can reach 900Wh/kg, making it a research and development hotspot.

The advantages of lithium rich base as a positive electrode material include:

High energy density and abundant important raw materials

Due to the short development time, there are currently a series of issues with lithium rich manganese based materials:

The first discharge efficiency is very low, the material undergoes oxygen evolution during the cycling process, posing safety hazards, poor cycling life, and low rate performance.

At present, the methods to solve these problems include coating, acid treatment, doping, pre cycling, heat treatment, etc. Although lithium rich manganese based materials have significant capacity advantages and huge potential, due to slow technological progress, it will take time for them to be launched in large quantities.
