The team published their findings in the scientific journal Nature Energy on Monday.
A statement from Samsung pointed out that the lithium metal anodes often used in all-solid-state batteries could trigger the growth of dendrites that would cause a reduction in lifespan and safety.
Dongmin Im, master at SAIT’s Next Generation Battery Lab and the leader of the project explained, “The product of this study could be a seed technology for safer, high-performance batteries of the future.
The Samsung announcement comes in the wake of a report that the Canadian utility firm, Hydro-Québec, would begin work on commercialising an all-solid-state battery co-invented by Dr John Goodenough, a professor at The University of Texas in Austin, and Dr Maria Helena Braga, an associate professor at the University of Porto in Portugal.
Back in 2017, when the all-solid-state battery prototype was developed, Dr Goodenough said he believed it could be brought to market in three years. The battery that he and Braga developed is a low-cost all-solid-state battery that will not combust. Battery life is long and charging is fast.
The Samsung team used a 5µm (micrometers) thick Ag-C layer in a prototype pouch cell. The ultra-thin Ag-C nanocomposite layer allowed the reduction of the thickness of the anode and an increase in energy density up to 900Wh/L.
The prototype was also about 50% smaller by volume than a conventional lithium-ion battery.
Samsung said the research would help increase the use of electric vehicles. "The prototype pouch cell that the team developed would enable an EV to travel up to 800km on a single charge, and features a cycle life of over 1000 charges," the company said.
