Solid-State Batteries and the Future of Wind Energy Storage
Is the era of the lithium-ion battery slowly coming to an end? In recent years battery manufacturers have all joined the race towards scaling the major breakthrough that is the solid-state battery.
What differentiates the solid-state battery from the lithium-ion battery is that instead of a liquid electrolyte it uses a solid electrolyte. If we break down the structure of a battery cell it consists of a cathode (positive pole) and an anode (negative pole) and a central separator. In the lithium-ion battery the separator is fully submerged in the liquid electrolyte allowing the ions to move between the cathode and anode. The solid-state battery on the other hand has a solid-state separator, which besides separating the cathode and anode, is an electrolyte that acts as the medium through which ions move.
On paper, the solid-state battery offers only benefits. It is much more eco-friendly due to the reduced use of toxic materials, it has a longer lifespan, can store more energy in a smaller size and is much safer due to the solid electrolytes being less flammable. This development will be particularly important for wind energy storage. With the better battery capacity and longer lifespan of the solid-state battery, the process of storing electricity for use during very low or no wind periods can be significantly improved.
However, manufacturers are facing roadblocks due to high manufacturing costs, and difficulty finding stable, reliable and highly conductive solid electrolytes. Additionally, transitioning the existing process from the lab into commercial-scale production is very complex. Although companies have been announcing the release of this type of battery, there isn’t a precise timeline confirmed, but many agree that it won’t be out before 2032. In the meantime, many manufactures are considering a hybrid solution where a portion of the liquid electrolyte is replaced by a solid material. Although it is not as efficient it is still a steppingstone in the direction of bringing the solid-state battery to the mainstream market.
There is still a lot of research and development needed, however, with industry collaboration and standardization, there is a chance to overcome these barriers faster.
