- Co-developing anode materials, silicon cathode materials,
and solid electrolytes for solid-state batteries and establishing a
global supply system
- Strengthening the competitiveness of next-generation
secondary battery materials and expanding business portfolio
through cooperation with Prologium
SEOUL, South Korea,
May 13, 2022 /PRNewswire/
-- POSCO Holdings has decided to cooperate with
Prologium solid-state battery manufacture, to develop core
materials for next-generation secondary batteries.
POSCO Holdings signed an agreement on the 12th to invest in
Prologium and to co-develop cathode materials, silicon cathode
materials, solid electrolytes for solid-state batteries, and
establish a global supply system.
Founded in 2006, Prologium developed solid-state batteries in
2012 and is selling them to manufacturers of small IT devices such
as smartwatches. The company is also attracting investment from
global investment companies and co-developing solid-state batteries
for electric vehicles with major automakers such as Mercedes-Benz
Group AG.
Whereas in conventional secondary batteries, electricity is
generated and charged through liquid electrolytes between the anode
and cathode electrodes of the battery, a "solid-state battery" is a
next-generation battery that replaces the liquid electrolytes
between the battery's anode and cathode with a solid and eliminates
a separator, which can secure safety and increase energy
density.
POSCO Holdings is securing its capabilities to develop materials
such as high-capacity anode materials and silicon anode materials
that can be applied to solid-state batteries and has strengthened
its capabilities to develop next-generation secondary battery
materials by establishing POSCO JK SOLID SOLUTION at the beginning
of this year.
