Huawei plans to invent solid-state battery tech, reveals new patent

Huawei has recently issued a new patent regarding solid-state battery tech. It would be a wonderful implementation in the energy storage sector. It will further act as a vital element for lithium-ion cells, ensuring faster charging and higher energy efficiency.

A solid-state battery is an electrical cell that contains a solid electrolyte instead of any liquid or gel. This solid component separates the anode and cathode, allowing ions to move between them while charging and discharging.

Inputs revealed that Huawei has applied for the solid-state battery patent with the title – “Doped Sulfide Materials and Preparation Methods, Lithium-ion Batteries.”

This invention will resolve the challenging battery problem: the breakdown of liquid electrolytes. Huawei will use a doped sulfide solid material instead of any liquid or gel electrolytes. This addition will boost the lifespan, safety, and performance of batteries.

As per the application, the tech requires a cubic crystal, a unit cell, and a doped sulfide with a high ionic conductivity. One side of the cell is doped in Nitrogen. The doped material and components offer better stability to metallic lithium-ion batteries.

Sulfide all-solid-state batteries ensure higher energy efficiency, excellent low-temperature performance, and faster charging/discharging. It reduces the risk of thermal issues, which is a quite common problem for the lithium-ion batteries.

The new technology is a boon, especially for future electric vehicles as well as energy storage systems. It further resolves the severe fading of battery capacity, often caused by polysulfide (LiSx) settling down in the liquid sulfur battery packages.

It is unclear when Huawei will introduce this significant technology in the real world. Although the company has taken its first step and we might hear a piece of good news by the next year, on this subject.
