TDK claims a battery breakthrough

We have not had one of those for a couple of weeks

TDK claims that it has creating a material which will revolutionise battery technology with a "significantly higher energy density" than current models.

Energy density measures the amount of energy a battery can store in relation to its size or mass. This innovative material is set to be integrated into TDK's CeraCharge solid-state battery, boasting an energy density of 1,000 watt-hours per liter — which is a 100-fold increase over its traditional solid-state counterparts.

The CeraCharge batteries use an oxide-based solid electrolyte, a stark contrast to the liquid electrolyte found in ubiquitous lithium-ion batteries, rendering them "extremely safe."

The company said that the advantages of solid-state batteries include their compact size, rapid charging capabilities, extended lifespan, and reduced susceptibility to temperature-induced damage.

The Tokyo-headquartered corporation stated, "The reduced size and enhanced capacitance lead to diminutive device dimensions and prolonged operational duration."

These batteries are intended to supplant coin-cell primary batteries commonly used in wearable technology such as wireless earphones, smartwatches, and hearing devices.

In line with the latest European Union regulations aimed at minimising batteries' ecological footprint, these new cells will be rechargeable.

TDK is actively progressing towards the mass production of these solid-state batteries, enhancing their capacity through advanced multi-layer lamination techniques and broadening their functional temperature spectrum.

TDK's CEO Noboru Saito said that while some might speculate a gradual downturn in our battery sales he did not believe it.

"I am confident that batteries will remain a sustainable and significant cornerstone of our corporate portfolio for the foreseeable future."
