The electrifying change in transportation Around the world, governments and automakers are promoting EV as a key technology to curb oil use and fight climate change. During the 2020 Presidential debate, Joe Biden pledged to transition the U.S. away from the oil industry. This will be no small feat considering that in 2020, petroleum products accounted for about 90% of the total U.S. transportation sector’s energy use. However, the larger players in the automotive world are already starting to pivot to EV: General Motors has said it aims to stop selling new petrol-powered vehicles and will move to battery-powered models4. Volvo said it would move even faster and will aim to only sell EV by 2030. Volkswagen has greenlit a plan to launch roughly 70 battery-powered models by 2030. Alongside Biden’s pledge to reach net-zero emissions, Europe is fast becoming the driving force in its support for EV. In the UK, PM Boris Johnson announced almost GBP2.4 billion of subsidies and support for charging infrastructure, EV development and production. Chancellor Angela Merkel’s government is offering carmakers and suppliers EUR5 billion to help weather the coronavirus crisis and invest in electric cars. www.sharecafe.com.au/2021/08/16/start-your-batteries-the-impact-of-evs-on-esg/One of the Australian companies at work on lithium battery technology is Calix.

It is/should be interesting to note that the Producers of new electric/battery powered vehicles will not discuss/provide MORE employment opportunities for the YOUNG Smart Phone Users. It seems that there will be MORE work for the producers of rubber/plastic Nose Caps for the Young Smart User of Smart Phones. More Time can/will be spent/wasted on Smart Phone Nose Rubbing.I wish I was YOUNGER and with a stronger rubber nose...to rub on a less silly Smart Phone!! BLAST...I hit the traffic light Metal pole...while I was rubbing MY silly rubber nose on MY SMART PHONE!

An Australian based 3 year trial was not encouraging when it came to battery storage solutions with high failure rates and problems with manufacturer support with many even going out of business before warranties on their products ended.
A universal type used in household batteries is lithium nickel-manganese-cobalt (NMC), used by companies such as Tesla and LG Chem. An additional chemistry composition is lithium iron phosphate (LiFePO, or LFP) - safer than NMC due to lower risk of thermal runaway, but it has lower energy density. There are some alternatives out there such as Lead-acid, advanced lead-acid (lead carbon), hybrid ion (salt water) batteries, molten salt batteries, and graphene. supercapacitors.
Flow battery are one of the most promising alternatives to lithium-ion, this type uses a pumped electrolyte (such as zinc bromide or vanadium ions) and chemical reactions to store charge and release it again. Redflow's ZCell battery is the main flow battery currently available in Australia.
Pros: They can be discharged to 100% of their capacity and have no residual discharge so they won't lose charge over time. They don't lose capacity over time. They operate well in high ambient temperatures. They're relatively easy to recycle. They should last for 10+ years.
Cons: Being new technology, they're relatively expensive compared to lithium-ion. They don't tolerate cold well (below 15°C). They require frequent maintenance which takes them temporarily out of service. Other types of Battery and storage technology are in a state of rapid development - technologies currently available include hybrid ion (salt water) batteries, molten salt batteries, and graphene supercapacitors. None of these are in common usage at present.

Another mining company in Australia hoping to gain some traction in the lithium battery market: Formerly known as Independence Group NL, IGO Limited (ASX:IGO) is an exploration and mining business that operates mainly in Australia. The recent sale of one of its major operations to Regis Resources (ASX:RRL) will see IGO become uniquely exposed to commodities critical to clean energy, being tier-1 nickel, copper, cobalt, and lithium.
