MIT startup 24M Technologies used sticky electrodes to
The main components of batteries arepositively and negatively charged electrodes and an electrolyte material that allows ions to flow between them. Traditional lithium-ion batteries use solid electrodes separated from the liquid by layers of inert plastics and metals that hold the electrodes in place.
In their design, the engineers replaced solid electrodes with a sticky electrode mixture, a liquid that carries positively and negatively charged particles. Inside the device, it mixes with the electrolyte.
The developers say that the rejection of the traditionalapproach provides a number of advantages. First, it eliminates the energy-intensive process of drying and solidifying electrodes in traditional lithium-ion manufacturing. Secondly, the need for inactive materials, including expensive metals such as copper and aluminum, is reduced by 80%. Finally, the energy density is increased in the new design.
Representatives of the company note that the createdThe battery can work with various combinations of lithium-ion chemistries. Therefore, the technology is a "platform" that can be used by various manufacturers.
We can use any chemistry on the market withoutchanges in customer supply chains. Other startups are trying to solve this problem in the future. Our technologies can solve this problem both today and tomorrow.
