Further gains from Talga high energy
battery anode product

Ongoing optimisation of Talga’s graphene silicon Li-ion battery anode product,

Talnode™- Si, returns further performance gains

Now delivers ~70% more energy density than commercial graphite-only anodes

Provides a “drop in” solution for improving current Li-ion battery performance

Commercial samples under confidentiality and material transfer agreements scheduled to commence delivery end of February - recipients include some of the world’s largest electronic corporations

Australian advanced materials technology company, Talga Resources Ltd (“Talga” or
“the Company” (ASX:TLG), is pleased to announce further test results from its high energy graphene silicon lithium ion (“Li-ion” battery anode product Talnode™-Si.
Following initial test results (ASX:TLG Oct 2018) further optimisation of Talnode-Si, with up to 15% silicon loading, has been underway at Talga’s battery material facility in the Maxwell Centre of Cambridge University, UK. Highlights of new half cell cycling test results include:

~70% higher reversible capacity (~600mAh/g) than commercial graphite (~350mAh/g)* (After 3 cycles)

Coulombic efficiency of 99.5% - 99.9% with first cycle efficiency ~ 91%

Up to 94% reversible capacity (after >130 cycles in a range of silicon loadings)

Talnode-Si consists of a mixture of silicon and graphene particles engineered by Talga to be suitable for existing Li-ion battery manufacturing equipment as a high performance, cost effective and scalable replacement for standard graphite anode materials. Commercial samples are being prepared, under confidentiality and material transfer agreements, with delivery commencing end of February 2019. Recipients include some of the world’s largest electronics companies. Development continues under the Safevolt project, a part of the £246 million UK-funded Faraday program, with Talga partners Johnson Matthey, Cambridge University and TWI. Based on the encouraging test results to date the Company has opted to progress to full cell testing and optimisation of Talnode-Si.

Is it just me or today's ado announcement showed very similar results to talgas latest ann 19/2/19?

Test work using Anteo fabricated silicon composites confirm reproducible production of 14wt.% silicon anodes which meet near-term industry target levels

The silicon composite anode containing 14% silicon achieved a 1st delithiation capacity of >600 mAh/g with an ongoing reversible capacity of 550 mAh/g

Cycle testing demonstrated capacity retention of >80% after 170 cycles

The silicon composite/graphite electrodes were then assembled into coin half-cells and tested for their cycling stability. Coulombic efficiencies of 99.8-99.9% were achieved over the course of the cycling test.

Talga's logo was also included on Anteo Presentation.....
Talga also attended the Osaka Japan Battery Conference.....

So is Talga using AnteoCoat??

Expand

Highly likely Anteo tech involvement , a long way to go yet for Talga anyway, these confidentiality agreements are giving shareholders the shites.
