Formation decides which lithium ions survive in your battery. Some ions move cleanly: fully wetted → solvated → intercalated Others get slowed, trapped, or consumed forming SEI before cycle 1 is even done. That’s your lost capacity. Most battery problems are transport problems in disguise.

The proof is in the patents- thanks @jasminsmajic.com for this deep dive.

These solutions are LCO, LFP, and NMC that have been analyzed by ICP-OES: which is which??? 🔋#battchat #batteries #greensky #energysky

Biologic taste on a Neware budget... If money were no object which cyclers are you buying? Thanks William Eggers for being our model! #battchat #batteries #greensky #energysky #energysky

Was a PhD a good investment? TBD. Was @joshuagallaway.bsky.social  an incredible advisor? No question. Battery Burn Book exists because of Josh. Credit where credit is due. 💁🏻‍♀️🔋 #battchat #batteries #greensky #energysky

This week's newsletter featured Izzy Voegels explaining a cylindrical cell winder. 🔋

Passing UN 38.3 ≠ being allowed to ship. It just means the real rules are about to show up. Shipping batteries is more than just an ops problem... check out today's post for more info 🔋💁🏻‍♀️#battchat #batteries #greensky #energysky

Na-ion batteries will not fully replace LFP, just as LFP didn’t fully replace NMC 🥊 This isn’t Survivor. You don’t vote one chemistry off the island. Batteries are a portfolio, not a popularity contest. Pick the chemistry for the job, not the hype cycle. 🔋🥊

LFP is the battery chemistry equivalent of showing up every day and doing the work. No cobalt. No drama. No fires. A polyanion cathode that traded range for safety, cycle life, and grid-scale dominance. Why boring beats impressive when failure is expensive #battchat

We are looking for companies capturing the mining to cathode active materials (CAM) supply chain in one entity.  If you are a brine to LFP or a brine to NMC company, we want to hear from you! Tag any #battchat companies that you know of in this space.

Who decided that academic papers have to be such boring reads? Asking for a friend...  If you’ve published a battery paper recently that you’re proud of we would love to hear the main takeaways in BBB sass style 💁🏻‍♀️🔋 #battchat #batteries #greensky #energysky

Cathodes are where battery performance goes to live or die. Energy density, power, lifetime, safety, it all traces back here.  We mapped the real tradeoffs across NMC, NCA, LFP, spinels, and Li-rich oxides. No rankings. No hype. Just physics. Link in bio 🔋 #battchat

Before a battery cell ships, it has to survive the Final Five: DCIR, OCV, self-discharge, EIS, and capacity grading; these tests catch every defect that slipped through upstream. They're the last interrogation before a cell enters the world. 🔋 🌎 #battchat

🔌💡Inflation Reduction Act has been solely responsible for most of the battery manufacturing growth in the last few years👇🏽 Even with these incentives, the US battery manufacturing capacity is 4x less than China's. The US needs more of this, not less. #battchat
