   This CPSC status report (dated 2018-02-12) is the most frequently cited aggregate figure for lithium-ion battery incidents in consumer products. The "more than 25,000" incidents over an approximately five-year window yields ~5,000 per year across ALL consumer product types — power tools, e-bikes, e-scooters, hoverboards, e-cigarettes, and power banks, not phones and laptops alone. The report does not break down by product category in the publicly available summary, so the phone/laptop-specific share must be estimated from recall data and NFIRS incident typing at roughly 20-25% of the total (≈1,000-1,250/yr). CPSC recall records show phones and laptops as one of the largest single product categories by unit count (Samsung Note 7: 2.5 million units; HP batteries: 50,000+; Dell: 4.1 million batteries). The native rate uses the ~1,250/yr upper end of the estimated phone/laptop share, NOT the ~5,000/yr all-category total — attributing the whole all-product figure to phones/laptops would overstate the device-specific rate roughly 4-5×.

   BU-304a: Safety Concerns with Li-ion

   Thống kê

   Lithium-ion cell failure rate better than 1 in 10 million; a 1 in 200,000 failure rate triggered the Dell/Apple recall of ~6 million laptop battery packs

   Trích đoạn

   “"The failure rate of a quality Li-ion cell is better than 1 in 10 million. … In 2006, a one-in-200,000 breakdown triggered a recall of almost six million lithium-ion packs." ”

   Battery University's per-cell failure rate of 1 in 1-10 million is the most widely cited engineering-level figure for lithium-ion thermal runaway under normal use. The 1-in-200,000 pack-level rate that triggered the Dell/Apple recall represents a manufacturing defect scenario — significantly worse than the baseline. A modern smartphone battery pack contains a single cell; a laptop pack contains 4-8 cells. Even at the baseline 1-in-10-million per-cell rate, the sheer volume of devices in circulation (300M+ smartphones, 150M+ laptops in the US) produces thousands of incidents per year at population scale. The per-cell figure and the CPSC population figure are consistent: 450M+ devices × ~4 cells average × 1/10,000,000 ≈ 180 expected cell failures per year at baseline, rising to thousands when manufacturing defects, damage, and aftermarket chargers are included.

   Battery University's per-cell failure rate is derived from manufacturer quality data and independent from CPSC's incident-report-based counting methodology. The two approaches (engineering failure rate vs population incident reports) provide genuine cross-validation.

   The Levin Simes compilation reports 12 deaths in NYC alone (2021–2023) and 19 micro-mobility fire deaths nationally, skewing heavily toward e-bikes, e-scooters, and hoverboards. Phone and laptop fires rarely cause fatalities because the battery energy density is lower and the devices are smaller; the primary harm is burns, property damage, and evacuation. For phones and laptops specifically, fatalities are likely in the low single digits per year nationally, making the outcome_severity serious_harm rather than fatal for this entry.
