First Tellurium Corp. (FTEL) continues to advance tellurium battery technology globally.

Researchers and scientists find adding tellurium to new and existing battery technologies can extend battery life up to 400 per cent.

CEO Tyrone Docherty sat down with Dave Jackson to discuss the advancements.

Current lithium-ion batteries use sulphur and selenium as electrode materials. Tellurium is a better conductor with a higher energy density.

Singapore’s Agency for Science, Technology and Research (A*STAR) researchers have demonstrated that electrodes made from tellurium can improve the energy storage and power output of rechargeable lithium-ion batteries.

Tellurium electrodes have higher energy densities and may be charged and discharged faster than conventional electrode materials.

The team then developed a cathode made entirely from tellurium nanowires just seven nanometers wide, which they laid together to form a mat.

This formed a flexible tellurium cathode with an energy density of 1800 milliwatt hours per cubic centimetre which allowed it to store 50 per cent more energy than a conventional lithium cobalt oxide electrode of the same size.

It also retained more than 98 per cent of its capacity after 80 charging cycles.

Not only is tellurium showing vast improvements in current lithium-ion batteries but in metal tellurium batteries, sulphur tellurium, zinc tellurium and new solid-state lithium batteries as well.

A research team at The University of Texas at Austin has found a way to stabilize lithium-sulphur batteries, making them more likely to become commercially viable.

Lithium-sulphur batteries deliver more use per charge and are environmentally friendlier, but degrade quickly over time. 

Coating the lithium electrode with tellurium protects the electrolyte from degrading, stunts the growth of deposits and lets the battery last longer.

The added layer of tellurium on top of the lithium metal inside the battery extends the battery’s lifespan by a factor of four compared to other lithium batteries.

“From Singapore to Texas, from Canada to Europe tellurium battery research has never been more active or promising,” stated Tyrone Docherty, CEO of First Tellurium.

“The superior conductivity of tellurium over other minerals is already prolific in solar panels, CDs, DVDs and semiconductors, and is now finding its way into the batteries of the future,” added Docherty.

The forecasted demand for tellurium already exceeds global supply without the added demand of the battery industry. 

Tellurium naturally occurring element found in the earth’s crust but is extremely rare.

The largest use of tellurium (Te) in the past decade or more has been in the manufacture of thin-film photovoltaic solar panels. Tellurium, along with cadmium, is an essential component of the thin photovoltaic layer which generates electricity from solar radiation.

First Tellurium Corp. (FTEL) is up 12.28 per cent, trading at C$0.32 at 1:10 pm EST.
