They made a semisolid electrode, in contact with a solid electrolyte material. The team solved the dendrite problem by adopting a compromise between solid and liquid states. But the promise is worth pursuing, Chiang says, because the amount of energy that can be stored in experimental versions of such cells, is already nearly double that of conventional lithium-ion batteries. So far, the current densities that have been achieved in experimental solid-state batteries have been far short of what would be needed for a practical commercial rechargeable battery. It’s been known that dendrites form more rapidly when the current flow is higher - which is generally desirable in order to allow rapid charging. Solid state batteries only make sense with metal electrodes, he says, but attempts to develop such batteries have been hampered by the growth of dendrites, which eventually bridge the gap between the two electrode plates and short out the circuit, weakening or inactivating that cell in a battery. But, he says, “the only way you can reach the energy densities that are interesting is if you use a metal electrode.” And while it’s possible to couple that metal electrode with a liquid electrolyte and still get good energy density, that does not provide the same safety advantage as a solid electrolyte does, he says. Solid-state batteries, Chiang explains, have been a long-sought technology for two reasons: safety and energy density.

The findings are described in the journal Nature Energy, in a paper by MIT graduate student Richard Park, professors Yet-Ming Chiang and Craig Carter, and seven others at MIT, Texas A&M University, Brown University, and Carnegie Mellon University. Now, researchers at MIT and elsewhere have found a way to prevent such dendrite formation, potentially unleashing the potential of this new type of high-powered battery. INCA Ingénieurs Conseils Associés, Niederanven (engineer) A.M.As researchers push the boundaries of battery design, seeking to pack ever greater amounts of power and energy into a given amount of space or weight, one of the more promising technologies being studied is lithium-ion batteries that use a solid electrolyte material between the two electrodes, rather than the typical liquid.īut such batteries have been plagued by a tendency for branch-like projections of metal called dendrites to form on one of the electrodes, eventually bridging the electrolyte and shorting out the battery cell. From outside of the Labyrinthe, visitors and passersby will be able to see the top of the tree-like form, reaching above the walls of the maze from all directions.įonds d’urbanisation et d’aménagement du plateau de Kirchberg, Luxembourg Each of its branches extends in a different direction, allowing for a panoramic view of the surrounding gardens, art works, and architecture. A thought in the brain travels through dendrites much like a human ascending the sculpture and both inevitably lead to the goal of processing the structures of our world. As one ascends the stairway, they encounter a point where they must choose one path that leads directly to an observation point, or select a second pathway that then also requires a further decision. The sculpture’s tree-like structure, requires visitors to choose a particular path to climb. Within the context of the Labyrinthe du Parc Central, Dendrite-a reference to the branched structure of the neurons that constitute our minds-provides visitors with the opportunity to climb above the encompassing walls of the maze, giving the chance to see the architecture of their pathway to the centre (as well as the vibrant surrounding landscape of the Plateau de Kirchberg), and, to preemptively observe their subsequent path to the exterior.
