New Developments in Li-ion Batteries

1. Polymers
Polymer lithium-ion batteries are developed on the basis of liquid lithium-ion batteries, with conductive materials as the positive electrode and carbon materials as the negative electrode. A generation of rechargeable lithium-ion batteries. Due to its more stable performance, it is also regarded as an updated product of liquid lithium-ion batteries. Many companies are developing this new type of battery.
2. Power class
Power lithium-ion battery: Strictly speaking, a power lithium-ion battery refers to a lithium-ion battery with a capacity of more than 3AH, which generally refers to a lithium-ion battery that can be driven by discharging equipment, equipment, models, vehicles, etc. The capacity of the battery may not reach the level of the unit AH. Power lithium-ion batteries are divided into two types: high capacity and high power. High-capacity batteries can be used in electric tools, bicycles, scooters, miner's lamps, medical equipment, etc.; high-power batteries are mainly used in hybrid vehicles and other occasions that require high current charging and discharging. According to the different internal materials, power lithium-ion batteries are correspondingly divided into liquid power lithium-ion batteries and polymer lithium-ion power batteries, collectively referred to as power lithium-ion batteries.
3. High performance class
In order to break through the storage bottleneck of traditional lithium batteries, a new iron-carbon power storage material that can store more power in a small power storage unit has been developed. However, the obvious disadvantage of this material before is that the charging cycle is unstable, and the storage capacity of the battery drops significantly after charging and discharging many times. For this purpose, a new synthetic method was used instead. They mixed several starting materials with a lithium salt and heated them to create a new nanostructured material with carbon nanotubes. This approach creates electrical storage cells and conductive circuits in one fell swoop on nanoscale materials.
The electricity storage capacity of this stable iron-carbon material has reached twice that of existing electricity storage materials, and the production process is simple, the cost is low, and its high performance can be maintained for a long time. Dr. Maximilian Fichtner, who led the research, said that if the potential of this new material can be fully exploited, the storage density of lithium-ion batteries could be increased by a factor of five in the future.
