Batteries for EV vehicles
Nano silicon for the battery anode is a recent development leading to a 15% increase in energy density and avoiding the use of graphite in the batteries. Sila Technologies is ramping up production to 150GWh per year over then next 5 years.
Sodium-ion battery chemistry has been keenly anticipated as alternative chemistry to lithium ion batteries in EV. Sehold have been first to market.
Compressed air battery using large underground vaults are being developed to provide long duration storage.
Flow batteries are a valid option for community and grid based storage. The advantages of low life, simple expansion works. Vanadium, iron, or zinc bromine based flow batteries will not be used in vehicles but deliver great grid and micro grid storage battery solutions.

It is becoming clear that batteries will drive the electrification of transport. Batteries are demonstrating that hydrogen and synthetic fuels are losing ground to the 22% learning curve of batteries. Biofuels may be the only transition fuel for long range aircraft.
Grid-scale batteries are an integral requirement to firm renewable energy, stabililise the grid with battery, wind and solar now the cheapest electricity.
Using a long lasting LFP battery in combination with an anode free battery with shorter lifespan is the approach taken by Our Next Energy. Like a petrol battery hybrid, the combination provides 1000 km of range, and long life.
Tesla has led innovation into grid, industrial and home storage with their range of batteries. The lines are blurred with home batteries now providing grid virtual power plant services.
Batteries made from CO2 compression and expansion have moved from lab to deployment. Offering low cost, longer term storage utilising standard equipment.
Direct lithium extraction is used in land based brines by a number of companies, but the vision is that the ocean has huge quantities, or could be extracted as part of desalination.
The total battery capacity for grid home and transportation is about 300TWh of batteries. This will take 10 years of manufacturing and ongoing of about 30TWh per year. Tesla aims to provide 10% of that battery capacity.

CATL announcement of their Qilin battery pack to be in production by 2023 exceeds Tesla’s 4680 battery and both exceed all other global batteries
Electrical management systems have evolved from their large diesel engine power plant buinsess. They have flexible energ
Hydro power is about 10% of the global energy production, but pumped hydro is being pursued as part of the solution for intermittent storage in renewable energy
What is the real figure of amount of lithium in a battery. The quantity of 6kg is elemental lithium. The quanty of Lithium carbonate equivalalent or LCE is used in mining circles and the quantity is about 60 kg. A large opportunity for efficiency improvement is clear.
Home and community battery is a smart way to reduce transmission costs and to improve reliablity of renewable energy. Losses in transmission are about 10% and batteries cost much the same whether close to consumers or at a solar farm.
While lithium ion batteries are the mostly widely used, other battery technologies are avalable that are competitive in some applications. Numerous other battery chemistries are in R&D phase
