"Japan’s TDK is claiming a breakthrough in materials used in its small
solid-state batteries, with the Apple supplier predicting significant
performance increases for devices from wireless headphones to smartwatches.
The new material provides an energy density—the amount that can be squeezed
into a given space—of 1,000 watt-hours per liter, which is about 100 times
greater than TDK’s current battery in mass production. Since TDK introduced it
in 2020, competitors have moved forward, developing small solid-state batteries
that offer 50 Wh/l, while rechargeable coin batteries using traditional liquid
electrolytes offer about 400 Wh/l, according to the group.
“We believe that our newly developed material for solid-state batteries can
make a significant contribution to the energy transformation of society. We
will continue the development towards early commercialisation,” said TDK’s
chief executive Noboru Saito.
The batteries set to be produced will be made of an all-ceramic material, with
oxide-based solid electrolyte and lithium alloy anodes. The high capability of
the battery to store electrical charge, TDK said, would allow for smaller
device sizes and longer operating times, while the oxide offered a high degree
of stability and thus safety. The battery technology is designed to be used in
smaller-sized cells, replacing existing coin-shaped batteries found in watches
and other small electronics.
The breakthrough is the latest step forward for a technology industry experts
think can revolutionize energy storage, but which faces significant obstacles
on the path to mass production, particularly at larger battery sizes.
Solid-state batteries are safer, lighter and potentially cheaper and offer
longer performance and faster charging than current batteries relying on liquid
electrolytes. Breakthroughs in consumer electronics have filtered through to
electric vehicles, although the dominant battery chemistries for the two
categories now differ substantially."
