“…The 2 MW/2MWh BESS was first installed to study its ability to complement rooftop solar for a variety of tests. Eventually, after research had been completed, it was used as a load‐serving resource, 13 being charged with solar energy during the day and discharging energy into the grid in the evening.…”

“…On April 19, 2019, at 4:22 p.m., the insulation monitoring device showed insulation fluctuations, suggesting that Rack #15, approximately in the middle of the container, was not electrically isolated 14 . Within about 32 min, Cell #7 in Module #2 of Rack #15 began to exhibit voltage decay, and within 8 s the BMS lost module‐level data 13 . Rear temperature readings for Rack #15 began to increase, but then the DC voltage recovered.…”

As the world continues to enact progressive climate change targets, renewable energy solutions are needed to achieve these goals. One such solution is large‐scale lithium‐ion battery (LIB) energy storage systems which are at the forefront in ensuring that solar‐ and wind‐generated power is delivered when the grids need it most. However, the perceived hazards of LIBs due to recent events in the United States and Australia pose a risk to their future success. When a battery energy storage system (BESS) has a multilayered approach to safety, the thermal runaway, fire, and explosion hazards can be mitigated. Successful implementation of this approach requires cooperation, collaboration, and education across all stakeholder groups to break down these preconceived notions. Much can be learned from the recent BESS fire and explosion events to inform safer design and operation. These events and their contributing factors share many commonalities with historic losses in the hydrocarbon industry. Fire and process safety engineers who have traditionally worked in the hydrocarbon industry can be of immense value to the BESS industry.

“…In contrast to state‐of‐the‐art Li‐ion batteries that typically comprise Ni and Co, Mg‐S batteries rely on abundant, non‐toxic Mg and S as electrochemically active materials. The risk of uneven Li deposition during charging (so‐called dendrites) causing internal short circuiting remains a safety concern for conventional graphite‐based Li‐ion insertion anodes, [1] and the risk is even more prominent for the long‐wanted Li metal anodes [2] . Albeit not being dendrite‐immune, [3] Mg metal anodes have an inherently lower propensity for dendrite formation than Li metal, possibly due to faster self‐diffusion [4,5] .…”

Performance Study of MXene/Carbon Nanotube Composites for Current Collector‐ and Binder‐Free Mg–S Batteries

The realization of sustainable and cheap Mg‐S batteries depends on significant improvements in cycling stability. Building on the immense research on cathode optimization from Li‐S batteries, for the first time a beneficial role of MXenes for Mg‐S batteries is reported. Through a facile, low‐temperature vacuum‐filtration technique, several novel current collector‐ and binder‐free cathode films were developed, with either dipenthamethylene thiuram tetrasulfide (PMTT) or S8 nanoparticles as the source of redox‐active sulfur. The importance of combining MXene with a high surface area co‐host material, such as carbon nanotubes, was demonstrated. A positive effect of MXenes on the average voltage and reduced self‐discharge was also discovered. Ascribed to the rich polar surface chemistry of Ti3C2Tx MXene, an almost doubling of the discharge capacity (530 vs. 290 mA h g−1) was achieved by using MXene as a polysulfide‐confining interlayer, obtaining a capacity retention of 83 % after 25 cycles.
