Why LFP Quietly Took Over Half the Battery Market — and What the Patents Show
Lithium iron phosphate has no nickel and no cobalt. It stores less energy and almost won anyway. The patents explain the cost logic that did it.

Patent of the Week: LG Energy Solution's 'Lithium-Free' Battery, Decoded
A June 2026 LG grant describes a secondary battery with no lithium-metal anode at the start. It's the anode-free idea that could cut cost and bulk at once.

Battery Recycling Is Becoming a Supply Chain, Not a Cleanup
Recovering lithium, nickel, and cobalt from dead cells is shifting from waste disposal to raw-material sourcing. Three recent patents mark the turn.

What Grid-Scale Storage Is Actually Made Of — Beyond the Battery
A utility battery is mostly not battery. The patents on energy storage systems show that the cells are the easy part; the power electronics are the business.

The Real Cost of Fast Charging — Why Speed Trades Against Lifespan
Charging a cell in minutes instead of hours is a chemistry problem, not just a power problem. The patents reveal what fast charging quietly costs.

The Separator: The Cheapest Part That Can Burn Down a Battery
A thin plastic film is all that keeps a cell's two electrodes from touching. When it fails, the whole cell does. A patent shows why this part punches above its weight.

Thermal Runaway: The Failure Mode That Defines Battery Safety
One overheating cell can cascade through a whole pack. The patents on stopping it explain why battery safety is mostly about containment, not prevention.

What Solid-State Batteries Actually Change — Read Through Toyota's and LG's Patents
Replace the liquid electrolyte with a solid one and several problems shrink at once. The sulfide-electrolyte patents show why it's so hard to do.

Does Battery Thermal Management Earn Its Cost? Read the CATL Patents
Keeping a battery pack in its temperature sweet spot adds plumbing, weight, and money. The patents explain what that buys — and why packs fail without it.

Why Silicon Anodes Are the Next Battery Bet — and Why They Keep Cracking
Silicon can hold far more lithium than graphite. The catch is that it swells and shatters. Three patents show how the industry is trying to fix it.

How a Battery Management System Actually Knows the State of Charge
The percentage on your dashboard is an estimate, not a measurement. Three patents show the math behind it — and why it drifts.

What a Lithium-Ion Cathode Actually Does — Read Through the Patents
The cathode is where most of a battery's cost and capacity live. Two granted patents from Samsung SDI and LG Chem explain the mechanism, and the trade-off.
