Not much new except maybe the guilty device in the official explanation of this damaging on-board ship fire last year: an exploding battery cell. CCTV evidence of the incident here (snapshots). For caption, see linked report.

The National Transportation Safety Board (NTSB) on Thursday cited thermal runaway of a cell within a handheld radio’s lithium-ion battery as the cause of a fire on an oil tanker docked in Baton Rouge, La., reports MarineLink.
The Liberian-registered oil tanker S-Trust was docked at the Genesis Port Allen Terminal on November 13, 2022, when a fire on the bridge was sparked by one of the cells in a lithium-ion battery for an ultra-high-frequency handheld radio exploding, the NTSB’s investigation found.
The batteries and chargers for the handheld radios were located on the communications table on the bridge.
By the time the vessel’s crew extinguished the fire, the S-Trust’s navigation, communication and alarm systems were damaged beyond use.
In total, the fire caused $3 million in damage to the vessel. No injuries were reported.
Lithium-ion battery cell explosions are typically caused by a thermal runaway, a chemical reaction that can cause the cell to ignite and explode, according to the NTSB. A lithium-ion battery cell can spontaneously experience a thermal runaway if damaged, shorted, overheated, defective or overcharged.
The NTSB said crews can help to prevent thermal runaways and ensuing fires by:
Following manufacturers’ instructions for the care and maintenance of lithium-ion batteries;
Properly disposing of damaged batteries;
Avoiding unsupervised charging; and
Keeping batteries and chargers away from heat sources and flammable materials.

Another thing that would be a good idea is to go back to Ni Cad batteries they don’t have a tendency to burst into flames.
I quite like a cheery blaze in winter.
Caused by politicians´CLIMATE CHANGE! ——Really sudden oxydation of lithium hydride (exposure to air).

SJTU researchers explore impact of intermittent overcharging on battery capacity and reliability
12 November 2023
In a paper published in the Journal of Power Sources, a team from Shanghai Jiao Tong University (SJTU) investigates the changes in electrochemical performance of Li-ion battery cells after conventional cycling and intermittent overcharge cycling and the causes of the changes.
Intermittent overcharging occurs during the long-term operation of cells due to inconsistencies among cells within the battery pack and the potential faults in battery management system. The results of the study indicate that:
The presence of intermittent overcharging accelerates capacity degradation and impedance rise in cells, which primarily result from secondary particles cracking, Li+/Ni2+ mixture, and transition metals dissolution, ultimately leading to the loss of cathode active material and lithium inventory.
The cells suddenly fail after about 100 cycles of intermittent overcharging, with the cause identified as the cumulative gas production resulting from side reactions between cathode and electrolyte, which eventually pushes the valve to bend, cutting off the internal electrical circuit. [bold added]
