A Bright Future: Vast Opportunities opened by Solid State Batteries

According to the latest research’s report, solid-state batteries are considered to be the path for the energy storage solution of the next generation

Normally any cell of commercial battery consists of electrolyte, anode, separator, and a cathode. Lithium-ion techno has been one of the most successful profitable batteries, which has been advertised since the beginning of 1991. But, their success around the world and the dispersion in the consumer electronics and more lately the electric vehicles cannot disguise their constraints when it comes to performance, form factor, safety, and expenses due to the core technology.

The most recent lithium-ion tech uses the liquid electrolyte with the lithium salts inclusive of the LiBF4, LiPF6 or the LiCLO4 in any organic solvent. But, the interface of the rigid electrolyte (SEI) which has been caused due to the decomposition of the electrolyte at the cathode, limits the conductance in an effective manner.

In addition to this, the liquid electrolyte requires costly membranes for the separation of the anode and the cathode as well as a non-permeable casing for the avoidance of leakage. Hence, the design and the size freedom for such batteries gets limited. Moreover, liquid electrolytes have several issues like health & safety because they make use of corrosive as well as flammable liquids. These risks have been specifically been highlighted by Samsung’s Fire gate that even many large companies have to incur when they make use of the flammable liquid electrolytes.

All such aspects are potentially addressed by the solid state electrolytes specifically in the drone markets, wearables and electric vehicles. The very first application of them was in the 1970s as main batteries for pacemakers. As you step forward in 2011, researchers from Tokyo Institute of Technology & from Toyota have made a claim about the finding of a sulfide-based substance which possesses the same ionic conductivity as that of any liquid electrolyte.  They were able to double that after five years hence making the solid-state electrolytes captivating for the applications of higher power and quick charging.
