Lead-acid battery, lipo battery or flow battery? Market is the only motivation.
renewable energy sources development needs large scam of electric power storage and energy power battery. It is not only about the energy but also the environment and eco-development problem.
So far there are several main energy battery type. Lead-acid battery is the first choice because of the related technology development. It is widely and well used on electrical bicycle, electrical motorcycle, electrical car, wind electricity storage and photovoltaic power storage. But Lead-acid battery has defect of low capacity, short life cycle and lead pollution in process of production and recycle. Most of Chinese big battery factory is researching on developing lead extracting technology. Now the lead extracting rate reaches 80%.
The second is Lipo battery. Tattu preprofessional UAV battery, It has advantage over others at energy capacity, power density and high transfering efficiency. Moreover its life cycle is longer. However its price is pretty high but low safety.
Flow battery is also among these, widely used in China. One of them, all-vanadium redox flow battery (VRB) is fast developing. As data shows, eight battery factories in China are about VRB.
All in all, different markets need different ar drone battery types. Therefore, it is hard to say what kind of battery will be replaced in the development of battery technology. It is finally motivated by market demands.
