Li-ion thermal runaway and abuse testing.

Solid-state battery abuse test in a dim laboratory — a cream-white ceramic electrolyte disc stands upright in a steel clamp beside a strip of bright silver lithium foil on a black anvil, a flat pouch cell on a scorched steel plate glows faint orange at one swollen corner and gives off a thin wisp of grey smoke with no flame, a thermal camera monitor behind shows the cell as a yellow and red hot spot on a blue field, a handheld gas monitor with an amber LED reads H2S 12 ppm, thermocouple wires run across the cell, and a technician in navy coveralls and safety glasses watches from behind a scratched acrylic blast shield

Solid-State Battery Fire Risk: A Sober Look at What Changes

A solid-state battery drops the flammable solvent, not the oxidizer or the lithium. Here comes what changes in thermal runaway, and what stays put.

Off-gas detection during a battery abuse test in a dim laboratory — a large prismatic lithium-ion cell stands on a scorched steel test frame with its safety vent just split open, a thin curl of pale white solvent vapour rises into a stainless steel collection hood with no flame anywhere, a small cylindrical gas sensor probe with a glowing amber LED hangs a few centimetres above the vent on a black cable, an instrumentation rack behind shows a rising green gas trace and a red GAS ALARM banner, thermocouple wires tape across the cell face, and a technician in navy coveralls and safety glasses watches from behind a scratched blast shield

Off-Gas Detection: The Warning Before a Battery Fire

Off-gas detection reads the vapour a failing cell breathes out before flame. Here comes the window it buys, the sensors that see it, and the limits.

Firefighters cooling a lithium battery fire at dusk on a wet training pad — a silver electric hatchback stands jacked on timber cribbing with its underfloor pack glowing orange and venting a sideways jet of flame, two firefighters in tan bunker gear and SCBA kneel behind a hoseline and drive a heavy water stream under the car, dense white steam rolls across the flooded concrete under portable floodlights, a third firefighter holds a thermal-imaging camera showing a bright hot spot, and a spent CO2 extinguisher lies discarded in the foreground puddle

Battery module propagation test in a dark laboratory — eight large prismatic lithium-ion cells stand clamped on a scorched steel table with thin white barrier sheets between them, the third cell vents a long jet of white-hot gas and sparks sideways while its neighbour glows dull red, grey vent gas rolls across the back wall, dozens of thermocouple wires run from the cells to an instrumentation rack showing live temperature traces, and two technicians in orange fire-resistant coveralls and hard hats watch from behind a scratched blast shield

Thermal Runaway Propagation: How One Cell Takes a Pack

Thermal runaway propagation turns one failed cell into a lost pack. Here comes the heat budget that decides it, and the design that stops it.

Wide overhead photograph at dusk of a low-rise New York City brownstone vestibule with a beat-up delivery e-bike leaning against the iron handrail of the front stoop; a single bright orange ember glows on the taped-up battery casing while a delivery rider in a quilted jacket walks past on the sidewalk — calm, unstaged street-level framing showing exactly where lithium-ion battery fires actually start, in residential entryways and stairwells of low-rise New York City buildings rather than open garages

NYC's 2023 Battery Fires: 268 Incidents, 18 Deaths

In one year, New York logged 268 lithium-ion battery fires and 18 deaths from e-bikes and e-scooters — and rewrote micromobility safety law.

Wide overhead photograph of an open multi-storey car park at dusk with a single white electric crossover parked in a marked EV charging bay glowing under a soft blue LED sign that reads CHARGING — beside it sit two ordinary silver and red gasoline sedans; a gentle wisp of pale white vapour curls from the rear wheel arch of the EV while the petrol cars sit silent — the calm neutral framing emphasises that EV fires happen far less often than gas car fires yet remain operationally harder to fight

Are EV Fires Really More Common Than Gas Car Fires?

Across U.S., Swedish, Australian, Norwegian and Polish data, EV fires happen 20 to 80 times less often than gas car fires per registered vehicle.

Side-by-side fire-safety laboratory thermal-runaway test on a clean white background — left: a single cylindrical green LFP 18650 cell on a stainless-steel rig venting a slow controlled plume of pale grey smoke from its scored positive vent with only a small dim flame, instrumented with thin K-type thermocouple wires; right: an identical purple-cased high-nickel NMC 18650 cell undergoing violent thermal runaway, ejecting a powerful directional jet of bright yellow-orange flame and white-hot sparks straight upward inside a turbulent black-edged smoke plume, casing visibly bulging

LFP vs NMC Battery Safety: Why Chemistry Decides Fire Risk

LFP vs NMC battery chemistry sets the fire risk before any vent opens. Here is why one chemistry burns hotter, vents more gas, and explodes more often.
