Zentek Delivers Update on Battery Technology Improvement

GUELPH, ON / ACCESSWIRE / October 28, 2022 / Zentek Ltd. (“Zentek” or the “Enterprise“) (NASDAQ:ZTEK)(TSXV:ZEN), an mental property enhancement and commercialization company, announces the commencement of a 4-12 months, $1.6M study undertaking in collaboration with Professors Mohini Sain and Ning Yan from the College of Toronto (“U of T”) and Ford Powertrain Engineering Exploration and Growth Centre (“PERDC”). Funding for the project involves $1.2M from the Mitacs Accelerate software. Prof. Sain is the Endowed Ford Motor Canada Chair in Sustainable Products in which he is lively in the subject of mild strength storage which includes mobile chemistry and renewable gas battery enhancement at PERDC, and Prof. Yan is the Tier 1 Canada Investigate Chair in Sustainable Bioproducts. Collaborating with the PERDC and screening at this facility is crucial to exhibit battery advances at a scale suited for the automotive industry.

“The Canadian government and the auto field have committed to devote in excess of $10 billion in battery producing in 2022 by itself. With the sizeable drive toward electrification in North The usa, we are energized to be operating with the team from U of T, who have labored with a amount of international battery producing providers,” stated Greg Fenton, CEO of Zentek. “This is an crucial investigate task to find to acquire future technology graphene-based mostly battery elements to likely increase vitality density, boost charging charges and strengthen battery safety.”

The undertaking seeks to check novel ideas for the reason of inventing multifunctional resources to be made use of in automotive battery parts together with anode, cathode, electrolyte, and separator. Zentek will be operating in tandem with U of T scientists offering and tests superior graphene materials including Zentek’s patent-pending anode product produced by Dr. Michael Pope (see Zentek’s push release dated February 18, 2022).

Update from Dr. Michael Pope’s Group at the University of Waterloo
Additional to Zentek’s press releases dated November 22, 2018 and February 18, 2022, Zentek has been collaborating with Dr. Michael Pope at the University of Waterloo for the final a few years, establishing battery technology to make improvements to anode effectiveness.

Just one extremely analyzed area for lithium-ion battery (LIB) growth is to enhance the anode substance. Presently electric powered vehicle anodes are composed of graphite, which has a confined theoretical specific potential of ~372 mAhg-1. Silicon (Si) has captivated major focus as a alternative content, generally due to its large certain capability of 4,200 mAhg-1, but also owing to its small doing work possible, lower value and the availability of silicon. Having said that, the industrialization of silicon anodes is hindered by an critical engineering roadblock: silicon has an huge volumetric fluctuation (bigger than 300% in all proportions) when charging and discharging. This element is the root result in at the rear of three key difficulties:

  1. Weak cycle life span thanks to self-pulverization of the anode.

  2. Irreversible capacity loss and low coulombic effectiveness.

  3. Destruction and reformation of the good-electrolyte interface, which consumes electrolyte and causes thickening and weak ionic mobility.

Making use of silicon in the anode substance, Dr. Pope has addressed these challenges, and has made a patent-pending graphene wrapped silicon anode materials.

Critical qualities of graphene-wrapped silicon anode, as declared in February 2022 contain:

  • At sensible mass loading of 2.5mg/cm2, the electrode achieved 2.04 mAh/cm2 and retained 79% of this potential after 200 cycles versus a lithium half-cell.

  • When paired with a business lithium iron phosphate cathode, the fully assembled battery retained 93.3% of its first capacity over 100 cycles.

  • Works with existing lithium-ion batteries as a substitute for graphite1.

Considering the fact that April, Dr. Pope’s workforce has optimized the anode material, which now has a unique ability of above 1,000 mAh/g and retains more than 80% of its capacity above 320 charge-discharge cycles. The precise capability of this product is a substantial advancement in excess of typical graphite anodes even so, the cycle life nevertheless necessitates enhancement when compared to usual electrical auto batteries, which drop about 4% potential more than 1,000 demand-discharge cycles. Zentek and Dr. Pope’s group will keep on to acquire this technological innovation with the aim of improving upon functionality to meet marketplace needs. Freshly optimized chemistries are achieving certain capacities as substantial as 1,500 mAh/g, an about 400% improvement around graphite anodes. This important enhancement in electricity density is complemented by impressive cycle balance. These functionality assessments ended up performed below accelerated protocols and will have to have to be confirmed in typical assessments.

Zentek submitted a patent software beneath the Patent Cooperation Treaty on May well17th, 2022.
