Batteries

According to SNE Research, their collective European market share has plunged from 60.4 percent in 2023 to the 30-percent range in 2025, while Chinese suppliers are climbing toward 60 percent.

China's exports of batteries and battery energy storage systems (BESS) have hit a record in 2025, soaring by 24% from the year before over the first nine months of the year.

Germany is the top overall market for China's batteries so far in 2025, with $10.5 billion in sales recorded just through September.

Battery exports to Saudi Arabia - by far the Middle East's largest battery buyer - are up nearly fourfold compared to 2024, while Latin America's top buyer Chile has posted a 320% rise in imports compared to 2024.

Oceania - driven mainly by Australia - and Africa - driven mainly by Nigeria, South Africa, the Democratic Republic of Congo and Egypt - have also posted steep expansions so far in 2025.

The number of recharge cycles still sounds low, but there is promise in ensuring the lithium is being re-used.

tl;dw: is it time for Li-Ion batteries (edit: that are being hauled in containers) to have a hazmat placard all their own?

Unlike lithium-ion batteries, vanadium flow batteries use electrolyte solutions containing vanadium ions to store and release energy. The technology offers a number of advantages for grid-scale storage: high safety (non-flammable), long cycle life (over 15 years), and the ability to decouple power and energy capacity, offering greater design flexibility.

This is big news for the Skellefteå factory. They were still ramping up production.

Seems like sodium ions batteries have left the lab and are already in production.

I'm working on setting up a DC UPS for my home network closet (router, NAS, cameras, etc). Ideally for simplicity, I would have these connected in parallel:

1. CV/CC power supply set to 3.3V/cell or ~70% SOC
2. 8s LiFePO4 battery, 25.6V nominal
3. Load (buck and boost converters to 5V, 12V, 48V)

The batteries I have in-hand are these: https://k2batterystore.com/collections/catalog/products/24v-11ah-lithium-iron-phosphate-battery

What I'm mainly concerned about is whether or not the batteries will properly maintain balance in this setup without a smart charger cycling them up to 100% SOC every so often. Does anyone have references or reading material on this subject?
