Battery technologies developed in Australia will be sold globally in the next five years through a partnership between the CSIRO and Japanese specialist chemical manufacturer Piotrek.

A statement from the CSIRO said the tie-up would see the emergence of the next generation of lithium battery technologies for portable electronic devices, drones and automotive vehicles. It would also fill a critical safety need with lithium batteries by helping prevent battery fires.

The collaboration between the two organisations has resulted in the next generation of Solid Polymer Electrolytes for lithium batteries using CSIRO's proprietary Reversible Addition-Fragmentation chain Transfer polymer technology and Piotrek's Ion Conducting Polymers.

Piotrek general manager Ihei Sada said the tie-up with the CSIRO would give his company a big advantage in the market.

“This partnership will help Piotrek make our batteries safer and more efficient, and with our industry reach, we will get our advanced batteries to the market faster,” he said.

“Together we will develop the world’s safest, longer life solid state high energy battery.”

Solid state batteries generally use a lithium metal anode, the highest specific energy of all battery anodes. This means the batteries have twice as much energy as those produced today.

There are no volatile or flammable liquids inside the battery that can catch fire at low temperatures if the cell is damaged.

CSIRO Battery Research leader Dr Adam Best said a number of firms were active in this field and there were proposals to have solid state battery enabled devices in the market by 2025, if not sooner.

"Our RAFT technology allows us to tune our SPEs’ properties to expand their versatility for different types of batteries and fuel cells, and will also significantly reduce the cost of device assembly and manufacture,” he said.

The CSIRO’s Dr John Chiefari, a co-inventor and co-developer of the RAFT polymer technology, has worked with Professors Maria Forsyth and Patrick Howlett from Deakin University’s BatTri Hub to develop the SPEs.

He said the Piotrek collaboration would bring together battery technologies to fast-track the development of an SPE for use in high energy (4.5-5V) lithium batteries for electric vehicles and drones.

“By developing and exploiting disruptive technology platforms, we’re supporting the creation of new businesses and industries for Australia and the world,” Dr Chiefari said.

“This development will underpin the growth of high energy batteries for the electric vehicle market."

LAYER 1 ENCRIPTION A KEY TO CYBER-SECURITY SOLUTION

Security requirements such as confidentiality, integrity and authentication have become mandatory in most industries.

Data encryption methods previously used only by military and intelligence services have become common practice in all data transfer networks across all platforms, in all industries where information is sensitive and vital (financial and government institutions, critical infrastructure, data centres, and service providers).

Get the full details on Layer-1 encryption solutions straight from PacketLight’s optical networks experts.

This white paper titled, “When 1% of the Light Equals 100% of the Information” is a must read for anyone within the fiber optics, cybersecurity or related industry sectors.
