|Hot Liquid Metal Grid Battery Mg Sb (Ambri)|
The technology is so promising that Bill Gates has personally backed the company along with Khosla Ventures and French oil conglomerate Total. This technology will literally enable clean renewable energy sources to replace toxic coal and antiquated nuclear power energy sources for base load capacity in national electric grids all over the world :)
The Energy Storage Module:
Each cell is a 1200Wh unit, which is assembled into a 100kWh stack, which is then assembled into a 2MWh Energy Storage Module (40ft standard shipping container).
These batteries are operated "hot" at a temperature that keeps the lighter liquid magnesium layer floating on top of the molten electrolyte salt layer, which floats above the liquid antimony layer.
The advantage of running the battery hot is that the components have extremely high calendar and cycle lives because the anode and cathode and electrolyte layers are density separated liquids that automatically configure into a battery cell and are not subject to any of the failure modes of low temperatures conventional batteries.
These liquid metal batteries can absorb tremendous amounts of energy quickly, which actually heats them automatically, and discharge the energy tremendously quickly, which also keeps them hot. By designing the battery to operate hot, all of the thermal management problems and failure modes of conventional batteries are avoided. This technology also makes use of low cost abundant materials (magnesium, salt and antimony) : which contrasts against the far less abundant and far more costly Lithium Cobalt Manganese Phosphorous Fluoride PET resources used in conventional high energy capacity batteries.
Cost Efficient Grid Energy Storage FTW
