Colloidal Battery
- Jul 26, 2018 -

It is an improvement of ordinary lead-acid batteries for liquid electrolytes. It adopts gelatinous electrolyte and has no free liquid inside. It has large electrolyte capacity, large heat capacity and strong heat dissipation ability in the same volume. It can avoid the thermal runaway phenomenon that is easy to be generated in general batteries. The electrolyte concentration is low and the corrosion of the plates is weak. The concentration is uniform and there is no acid stratification.

Nickel-metal hydride storage battery (Ni-MH)

Ni-MH batteries are rookies in the battery family that emerged in the 1990s and are growing rapidly. The electrode reaction of the Ni-MH battery is:

Positive electrode: Ni(OH)2+OH-= NiOOH+H20 +e-

Negative electrode: M+H2O+e=MHab+OH-Ni(OH)2+M=NiOOH+MHab

It is the same alkaline battery as the nickel-cadmium battery. It only replaces the cadmium cd of the negative electrode material in the nickel-cadmium battery with the hydrogen storage alloy material (mh), and the electromotive force is still 1.32v. It has all the excellent characteristics of nickel-cadmium batteries, and its energy density is higher than that of nickel-cadmium batteries. The main advantages are: higher specific energy (longer distance for one charge); higher specific power, smooth discharge during high current operation (good acceleration of climbing ability); good low temperature discharge performance; long cycle life; safe and reliable, Maintenance-free; no memory effect; no pollution problems to the environment, renewable, consistent with the concept of sustainable development. However, Ni-MH batteries are too expensive and expensive.
