Batteries

Batteries are an integral part of our lifes. From TV remotes to phones, to toothbrushes, doorbells, toothbrushes to pacemakers. An for some, electric bikes, electric cars, and electricity storage. We have drawers full of spares, and the revolution is moving from powering our lifes to powering the world. In themselves they do not create electricity. A single use battery is ok, if it lasts a long time in our pacemaker, but not much use in vehicle or for electricity supply. Unlike fossil fuels, batteries are are technology. They do not capture energy or burn fuel. But when paired with a source of energy, they free us from wires, providing freedom and independence.
Batteries are the standout technology enabling build-out of renewable energy. Even the Economist has a glowing report saying they are the clean energy’s next trillion-dollar business [1]. Like solar panels invented 70 years ago, batteries have 40 years of use from consumer products to now cars and grid storage. A comment from the Economist was “Batteries have done in five years what took solar 15 years.” Fatih Birol from IEA, says “Batteries are changing the game before our eyes.” Note that IEA has a dreadful record with predicing solar rise of 25 years late and 7 times too little.
Batteries have continued their march of increasing energy density. Wrights Law states that manufacturing costs will reduce up to 15% for every doubling in production. Essentially, the more we make of an item, the better we become at doing so. Costs of batteries have declined 97% over the past 20 years and 90% in just the past 10 years and we will explore these in more detail below.

Batteries are essential for the renewable energy transition. They enable storage of excess solar power, reducing reliance on fossil fuels. Tesla’s recent announcement of producing 100 million 4680 batteries highlights the rapid advancements in battery technology. This progress is crucial for a sustainable energy future, for electric transport and grid storage to enable full production by solar and wind for the end of the fossil fuel era

Solid-state batteries are the next big thing in battery technology but unfortunately, Toyota’s failure with solid state batteries is clear to see since 2009. Even in 2023, Toyota continues to release announcements now with a prospective launch day of 2027/2028. Three questions remain unanswered Whole Mars Blog was the inspiration to put this down for
