Solid-State Battery: a battery revolution is coming

An article by Anne-Françoise Pelé for EETIMES in collaboration with Milan Rosina, Principal Analyst, Power Electronics & Batteries, and Shalu Agarwal, Technology & Market Analyst, Power Electronics & Materials, both from Yole Développement (Yole)How solid-state battery commercialization will reshape the e-mobility business.

The solid-state battery as an alternative to the conventional liquid-electrolyte lithium-ion battery

Lithium-ion (Li-ion) batteries have become the technology of choice for many applications. Li-ion battery-powered systems range from mobile phones, laptops, and power tools to electric vehicles, electric trucks and buses, and even electric aircraft. The traditional lithium-ion battery comprises a cathode, anode, separator, and liquid electrolyte. The flammable liquid electrolyte is responsible for Li-ion battery safety issues, such as electrolyte leakage, fire, or explosion. In a solid-state battery, as its name suggests, the flammable liquid-electrolyte is replaced by a solid-state electrolyte, which results in greater safety and enhanced battery characteristics. Solid-state battery development aims for a next-generation battery with higher energy density, fast charging capability, lower cost, and greater safety.

Solid-state batteries have many potential applications across multiple industries, such as automotive, consumer electronics, industrial, aerospace, etc. There are two distinct categories of solid-state batteries: solid-state batteries with a very small energy capacity, already commercially available from several suppliers, aimed at applications in consumer electronics, while the biggest drive is for large-energy capacity (“bulk”) solid-state batteries for electric and hybrid electric vehicles (EV/HEVs).

Electric vehicles as a key driver for solid-state battery development

Internal combustion engines (ICEs) have powered automobiles for more than 100 years, but the era of the ICEs is now coming to its end. EVs will progressively replace ICE vehicles and become mainstream in the automotive industry in the coming years.
