Harvard University in the United States develops flow battery packs to help with energy storage

With the current popularity of renewable energy, the energy storage market has great
potential for development.
Tesla hopes to further explore the energy storage market
with the research and development of lithium battery packs for electric vehicles.
The research team at Harvard University believes that in addition to lithium battery packs, there must be a more suitable structural design
for energy storage.
Professor Michael Aziz and his team are developing flow battery packs that are said to have some properties that are more conducive to energy storage
.

In a flow battery cell, the liquid electrolyte circulates in two container boxes, which are separated
by a membrane.
Ion transfer is achieved by passing through the membrane, and the whole process is similar
to the power generation principle of hydrogen fuel cells.
Adjusting the size of the two container boxes can change the storage capacity of the flow battery pack, while the area of the film controls the size of
the power output.

Researchers said that even if the flow battery pack is left for a long time, the power will not be lost, and the extreme temperature conditions will not affect
the power storage.
In addition to this, flow battery packs will be cheaper
than lithium-ion products with the same storage capacity.
Compared to lithium battery packs, the flow battery pack prototype being tested uses more conventional and readily available materials, and is safer than previous designs
