UK consortium to make graphite-based anode for solid-state lithium-ion batteries

A consortium funded by the UK’s government will work toward developing a graphite-based anode to allow solid-state batteries to meet the performance demands required by electric vehicles.

The project will replace metallic lithium anodes in solid-state batteries with consortium partner Talga Technologies’, a subsidiary of Australian firm Talga Resources’, graphite carbon anode Talnode-E product.

Partnership aims to commercialise next gen solid-state batteries within five years

Wed, 09/18/2019 - 14:59 -- Paul Crompton

A partnership to develop solid polymer electrolytes (SPEs) for lithium batteries has been made between Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Japanese chemical manufacturer Piotrek.

The companies hope to fast- track the development and commercialisation of an SPE for use in high energy (4.5-5V) lithium batteries for electric vehicles and drones by 2025.

SK Innovation ‘in battery venture talks with VW, China’

Fri, 04/12/2019 - 12:54 -- Hugh Finzel

South Korea’s SK Innovation (SKI) is reportedly in talks to establish two separate battery production joint ventures— one with Volkswagen and another with Chinese partners.

SKI confirmed talks with Volkswagen in an interview with Reuters, saying the two companies were discussing building a factory together. SKI also said I was “on the cusp” of agreeing plans to build a plant in China with “undisclosed partners”.

The president of SKI’s batteries business YS Yoon told Reuters: “Our strategy is to keep up with technological advancement by having relationships with some of our key customers. Compared with rivals, we’ve been matching or exceeding investment in the (EV batteries) area since last year.”

Battery storage hybrid planned for UK ‘energy superhub’

Fri, 04/05/2019 - 09:03 -- John Shepherd

UK companies are behind plans to install a hybrid storage system of lithium-ion and vanadium redox flow batteries at the heart of a new ‘energy superhub’ in the English city of Oxford.

The superhub consortium— which includes UK energy storage company redT and Pivot Power— said the project would study how the growth in local renewables, electric vehicles, battery storage, and demand side response can be supported and help in reducing charges to consumers.

Pivot Power will create a connection to the transmission network for the system that will combine the lithium-ion battery with “2 MW / 5 MWh of the heavy cycling, non-degrading characteristics of vanadium redox flow machines”.

Bolivia and India are working on plans to set up a lithium supply chain between the countries to serve joint venture battery production plants.

Lithium carbonate originating in Bolivia would be delivered to the battery/cell manufacturing facilities in India, according to an agreement signed by Indian president Ram Nath Kovind (pictured left) during a state visit to Bolivia.

Under the terms of the deal, both sides “agreed to facilitate mechanisms for the commercialisation of lithium carbonate and potassium chloride produced in Bolivia by the state-owned exploration and refining firm Yacimientos de Litio Bolivianos Corporación (YLB).”

Artificial intelligence (AI) can be used to “accurately predict” the remaining useful life of lithium-ion batteries before they start to wane, according to new research.

Scientists at the Massachusetts Institute of Technology, Stanford University and the Toyota Research Institute, said their work could speed up battery development and improve manufacturing to help new designs get to market faster.

Report co-lead author Peter Attia said potential applications of the research included shortening the validation time for new chemistries.

Ban Pha Dan

Australia-based Redflow has provided a hybrid battery system coupled with solar energy generation to create a microgrid that will provide a reliable power supply in a remote village in Thailand.

The energy storage system is made up of 10 Redflow ZBM2 zinc-bromine flow batteries— which provide 10kWh apiece— and three lithium batteries. The ZBM2 batteries will provide power to the Ban Pha Dan community school, town hall, and temple, while the lithium batteries will supply energy for individual homes.

Ban Pha Dan is in Lamphun province and is surrounded by a wildlife reserve where power pylons are not permitted, meaning that the village has lacked access to electricity in the past.
