The battery liquid in the case of conventional lithium-ion batteries acts as a conductive medium between two electrodes and is a cause of fire hazard. The charges moving in the liquid is also having a gel-like consistency, so-called electrolytes.
If there is any internal damage within the battery, it might suffer a short circuit leading to massive exposure to the sun, and the liquid electrolyte may ignite, resulting in a debatable battle of extinguishing the calamity
However, in the case of solid-state batteries, the chances of facing such a risk with fire are very less. Also, the range is advantageous in the case of solid-cell batteries. It also doesn’t require any additional cooling for the conductive medium between the plus and minus poles as required in lithium-ion batteries.
Hence saving space and increasing in weight as well a higher energy density in solid-state batteries. So you can have more current in the same volume compared to it the liquid.
But, nothing comes flawlessly, in the case of solid-state batteries also the statement holds. The major issue is the low amperage with which it can be charged or discharged.
But the researchers from Fraunhofer Institute for Silicate Research ISC in Würzburg are counteracting the weak points. The team is working together with battery manufacturer Varta and other cooperation partners. They have formed a Solid consortium for batteries to develop based on sol-gel materials with lithium metal anodes to series maturity.
The project has been with 3.2 million euros by the Federal Ministry of Education and Research.
According to their statements, Forschungszentrum Jülich already made a breakthrough in solid-state batteries. A special solution has been found for charging and discharging the current at ten times higher than the current state.
The team is relying on components from phosphate compounds.
As per Media reports, companies from China are also into solid-state batteries. A spin-off from the Tsinghua University of Technology, Qing Tao Energy Development is also developing solid-state batteries with a capacity of 100 MWh per year.
The number shows enough for 2000 electric cars, with an investment of 144 million euros in the production facility.
Even the Samsung Advanced Institute of Technology (SAIT) from South Korea also announced in March 2020, a groundbreaking prototype for its lithium-ion battery technology successor. It clearly shows how solid-state batteries are important for the upcoming future.
