What are the latest battery technologies?

1. Battery technology

The battery technology was first invented. At present, there are mainly two types of lead-acid batteries and gel batteries, both of which are relatively bulky batteries. Most of the batteries used in electric bicycles on the market are lead-acid batteries.

Lead-acid battery technology

Basic research on lead-acid batteries (including positive electrode, negative electrode, grid)

Other research hotspots (such as start-stop and micro-hybrid, light bicycles, etc.)

Electrochemical performance of nano-lead dioxide used as positive electrode active material The microstructure and morphology of the positive electrode active material (PbO2) have a great influence on the electrochemical performance of lead-acid batteries. Nano lead dioxide has a microsphere structure.

Preparation: The method is very simple, namely using cetyl trimethyl ammonium bromide as a structure directing agent. Test: The thin positive electrode of the test lead-acid battery is made by coating nano-lead dioxide microspheres on lead alloy sheets. The electrode tested had a discharge capacity of 101.8 mA g1 (ie, 45% active material utilization) and showed good cycle life.

Conclusion: The special form of lead dioxide morphology plays a crucial role in the improvement of discharge performance.

Lead-acid battery negative plate carbon additive

Carbon additives have shown significant improvements in reducing sulfation of negative plates and improving cycle performance as well as charge-discharge acceptance, both in valve-regulated sealed cells and flooded cells.

However, other properties such as high-rate charge-discharge and water loss are degraded by the addition of different amounts of carbon additives. Experiments show that the reduced charge-discharge performance and water loss at high rates are due to part of the lignosulfonate adsorbed on the activated carbon surface. This will limit the utilization of the lead surface lignosulfonates of the negative active material. The presence of lignosulfonate on the lead surface is decisive for the formation of the lead sulfate porous layer. When the lignosulfonate concentration of the negative plate was properly adjusted, both high-rate discharge performance and water loss could be recovered to acceptable levels.
