<2022> Solid State Electrolyte Technology Trend & Market Outlook (~2030)
With the
growth of xEV battery industry, there has been growing interest in emerging
products of the next generation. All-solid-state battery is one of the key
players among the newcomers in the market. Major companies in the industry have
been bracing for new challenges ahead by outlining their future roadmaps. The
all-solid-state battery sector is expected to flourish around 2027. The K-trio
battery makers as well as non-Korean companies on the global stage such as
Toyota in Japan and QuantumScape in the US have been working behind-the-scenes
to take a leading position in the market.
Among
the K-trio companies, Samsung SDI recently started the establishment of pilot
line, named 'S line,' for all-solid-state battery in Suwon, Gyeonggi-do
Province. The S Line, constructed on a 6,500 square-metre premise, will
encompass related manufacturing infrastructure such as solid electrolyte
production facilities.
LG
Energy Solution has been working on the development two different types of
all-solid-state battery - polymer and sulfide - at the same time. SK On has
agreed to cooperate with SOLIDpower in the US about the R&D of
all-solid-state battery.
SNE
Research, one of the most influential market research institutes in Korea,
forecasts the all-solid-state battery market to grow from 2GWh in 2021 to
135GWh in 2030. It is expected that all-solid-state battery may join the mainstream
in 2035.
The
concept of all-solid-state battery was first proposed in the late 1970s.
All-solid-state battery has flammable liquid electrolyte / separator replaced
by non-flammable / flame-retardant solid electrolyte which acts as
ion-conductive electrolyte and separator. All-solid-state battery, though, has
not received much recognition for a long time with only research on solid
electrolyte conducted for academic purpose. However, after Toyota in Japan
unveiled its prototype of all-solid-state battery using the sulfide solid
electrolyte in 2010, all-solid-state battery has drawn a great attention from
the world. After that, related research has become noticeably active, and at
present, candidate materials for solid electrolyte including oxide, sulfide,
polymer, and organic / inorganic hybrid materials are all subject to active
research of today.
Most of
the next-generation, high-capacity/high-power (high-voltage)/ large-size lithium-ion
batteries, that have been subject to the recent research and development, use
the organic liquid electrolyte, which is superior in ion conductivity, but at
the same time, is highly volatile, thus inevitably creating anxiety about the
safety of batteries. There have been researches on electrolyte, separator and
electrode materials, with an aim to secure the safety of lithium-ion battery,
but any research on the all-solid-state battery system based on solid
electrolyte, which can address the fundamental safety issues with battery, have
not kicked off yet. In general, when moving from liquid to polymer gel and
then, solid electrolyte on the spectrum of electrolyte, the safety level of lithium-ion
battery increases. On the contrary, the electrochemical reactiveness
deteriorates as the electrolyte becomes solid. Such deterioration is caused by
low ion-conductivity of solid electrolyte and high interfacial resistance due
to reduced contact area. All of these added up to become a major obstacle for
the commercialization of all-solid-state battery. To address these issues,
there have been brisk research movements across the industry.
To
secure the safety of next-generation, high-capacity / high-power (high-voltage)
/ large-size lithium-ion battery, it has become critical to develop lithium ion
batteries using the solid electrolyte. In addition, there are hightened
expectations on the potential commercialization as industry leaders in Japan
and the US have begun their research projects in earnest.
