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.

Side-by-side fire-safety laboratory test showing a swollen LiPo battery pouch cell on the left with bulging aluminium-plastic laminate and exposed jellyroll layers, next to a vented 18650 cylindrical lithium-ion cell on the right emitting a bright directional jet flame from its scored positive-terminal vent

Why a LiPo Battery Is Really a Lithium-Ion Battery

A LiPo battery is a lithium-ion battery. The polymer only names the gel and pouch. Here is why that matters for fire safety.
