⚡ Welcome to The Weekly Authority, the Android Authority newsletter that breaks down the top Android and tech news from the week. The 204th edition here, with Pixel 6 pre-orders, a confirmed Unpacked date, OnePlus 10T launch date, a clip from The Last of Us: Part 1, and more!

🥵Pleased to report I survived the UK heatwave and have been playing God of War; better late than never — and so far, I’m impressed and pretty excited for God of War: Ragnarok in November.

Weekly Wonder

In the ongoing quest for alternatives to lithium-ion batteries, a Swedish battery maker is looking to make batteries from trees, which sounds pretty interesting.

  • Northvolt AB plans to use carbon in wood from Nordic forests to reduce cost and environmental impact.
  • Working with Stora Enso Oyj, a Finnish forestry company, it will use lignin to create the anodes for its batteries, entirely sourced from raw materials.

What is lignin?

Lignin is “a plant-derived polymer found in the cell walls of dry-land plants.”

  • Trees are composed of 20-30% lignin.
  • It’s one of the planet’s biggest renewable sources of carbon.
  • Stora Enso is the largest kraft lignin producer in the world, making 50,000 tons a year at its Sunila site in Finland. The lignin is used to create the company’s anode material, Lignode.

How are lignin-based batteries made?

  • During the production of cellulose fibers, lignin is separated from wood, before being refined into a lightweight carbon powder.
  • This powder is then made into electrode sheets before being combined with other battery components.
  • The resulting material can be used to replace graphite, usually required for lithium-ion batteries to function.

Are wood-based batteries the future?

Almost all our portable electronics, such as smartphones and tablets, use lithium-ion batteries.

  • These days many EVs are also powered by lithium-ion batteries.
  • With the world expected to see over 25 million EVs on the road by the end of 2022, it’s clear we need to look at alternatives to lithium-ion batteries.
  • Because graphite is formed through a chemical reaction that takes place in unrenewable carbon compounds, it’s not a sustainable material.
  • Tesla would have to mine over 1 million tonnes of graphite to meet production targets of 20 million EVs annually.
  • Companies like Aptera have already looked at alternatives such as solar-powered vehicles.
  • But could lignin-based batteries be the solution the world has been looking for?

Why are wooden batteries more sustainable?

There are a number of reasons why these wooden batteries are better for the planet:

  • They’re sustainable: Materials will be sourced from sustainability-certified European forests.
  • They’re scalable: Trees are a widely available natural resource, meaning these batteries could be produced commercially.
  • They’re renewable: Most lithium-ion batteries are manufactured in China, but using natural resources would change all this.
  • They charge faster: Stora Enso claims a lignode battery has the capacity for faster charging than fossil-fuel-powered batteries.
  • They’re better at lower temperatures: Lithium-ion batteries are known to overheat, causing concerns about their use in EVs and larger vehicles. These wooden batteries are operational under cooler temperatures, making them a better choice for automotive use.

Northvolt began its first shipments to automakers in May, so we could see these batteries being used more widely in the coming months…

Tech Tweet of the Week

Turns out, real cats are loving Stray, and there’s even a Twitter account dedicated to the trend:

Something extra: Why the Japanese calendar is full of unofficial food holidays — It’s all about wordplay (tasty, tasty wordplay).

Have a great week!
