Solid lithium battery breakthrough

Are solid-state lithium-metal batteries better than traditional lithium-ion batteries?

For decades, researchers have tried to harness the potential of solid-state, lithium-metal batteries, which hold substantially more energy in the same volume and charge in a fraction of the time compared to traditional lithium-ion batteries.

What makes TDK a solid-state battery?

Utilizing TDK’s proprietary material technology, TDK has managed to develop a material for the new solid-state battery with a significantly higher energy density than TDK’s conventional mass-produced solid-state batteries (Type: CeraCharge) due to the use of oxide-based solid electrolyte and lithium alloy anodes.

How do lithium-metal batteries work?

The big challenge with lithium-metal batteries has always been chemistry. Lithium batteries move lithium ions from the cathode to the anode during charging. When the anode is made of lithium metal, needle-like structures called dendrites form on the surface.

Can solid-state batteries make a significant contribution to energy transformation?

“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.

Are solid-state batteries ready for production in 2025?

Solid-state batteries have long been touted as the technological breakthrough that electric car makers are striving to bring to market. Finally, it looks like 2025 could mark a crucial step on the technology's path to becoming ready for production.

How long do lithium-sulfur batteries last?

It maintained over 80% of its initial capacity after 25,000 charge/discharge cycles. This far surpasses the durability of lithium-ion batteries, which degrade after approximately 1,000 cycles. Despite these achievements, questions remain about the energy density of lithium-sulfur batteries.
