Batteries the focus of Japan's EV market, with domestic automakers adopting lighter, more efficient packs and technologies popular with Chinese manufacturers. https://www.japantimes.co.jp/business/2025/10/19/companies/ev-battery-race/?utm_medium=Social&utm_source=mastodon #business #companies #electricvehicles #carmakers #batteries #suzuki #honda #nissan #china #byd
Chinese battery giant CATL has announced a new Sodium Ion battery pack for EV that is game-changing. It features:
⦁ 10,000 charge cycle lifetime to 85% capacity
⦁ 90% power capability at -40℃
⦁ 175 Wh/kg energy density, behind Li-Ion at 300 Wh/kg
⦁ no thermal runaway danger
⦁ cost $19/kWh, compared to $50/kWh for Li-Ion
This will be ideal for mid-range, low cost EVs, and for grid batteries. They start mass production in 2026.

The thing about batteries (and renewables, but REALLY about batteries) is the sheer volume of research (both in labs, company R&D and deployed) along with the pletora of research directions to choose from.
We are still at the bottom of the hill for battery and energy storage research.
With its commanding position in the battery industry, China has identified another point of leverage in trade talks as the U.S. increasingly needs energy storage to support data centers and stabilize the grid. https://www.japantimes.co.jp/news/2025/10/13/world/politics/china-us-trade-batteries/?utm_medium=Social&utm_source=mastodon #worldnews #politics #china #batteries #us

Head's up Bicycle Folks. Recall on bicycle lights.
"Product
Knog Blinder 900 and 1300 bicycle lights
Issue
Consumer products - Fire hazard
What to do
Immediately stop using the recalled product, safely dispose of it at a local recycling facility that accepts lithium batteries and register for a free replacement.
Details: The light’s lithium-ion battery can overheat (thermal runaway) and pose fire and burn and hazards.

If you're storing anything battery-powered (flashlight, radio, etc.) as part of your emergency supplies, don't store it with alkaline batteries inside. When they inevitably leak, they'll damage or destroy the device. Much better to rubber-band them to the outside.

Fascinating tech, but 2400°C molten tin just sounds scary.

Who remembers the number 800 torch battery? I was talking to someone about batteries and I remembered these from my youth.
I don't think I've seen any physical ones since around 1970, back then but they were popular for cycles.

China’s solar, battery and electric vehicle companies have expanded their foreign investment plans in recent years, having pledged more than $210 billion since 2022. https://www.japantimes.co.jp/business/2025/09/10/tech/china-green-tech-overseas-factories/?utm_medium=Social&utm_source=mastodon #business #tech #china #renewables #wind #solar #energy #batteries
During the workshop "And what if we cooked with batteries?", @marieverdeil & @dasha invite you to join them in the research on energy, its storage, use and materiality they started during their current residency at iMAL.
We will discuss alternatives to current energy models, while trying to make energy more tangible through playful exercises and DIY prototypes that will remind us what a Watt is. We will collectively explore the history of batteries, discuss their challenges and shortcomings, make our own batteries, and who knows, we might even cook with them!

If you're not already locked in, I highly recommend checking out sodium ion batteries.
Friends of mine got some about a year ago, ordered directly from a supplier in China, and can't stop singing their praises. They reckon they're cheaper per unit of capacity, last longer even with full cycling, and of course they come with zero fire risk : ) Also they're free of conflict minerals, easier to recondition/ recycle, and fairly nontoxic at EOL.
