Energy storage battery manufacturing and production safety issues

What challenges does battery production face?

The rise in battery production faces challenges from manufacturing complexity and sensitivity, causing safety and reliability issues. This Perspective discusses the challenges and opportunities for high-quality battery production at scale.

Are solid-state lithium-metal batteries safe?

Try again? Solid-state lithium-metal batteries (SSLMBs) with high energy density and improved safety have been widely considered as ideal next-generation energy storage devices for long-range electric vehicles. Nevertheless, the potential safety issues in SSLMBs during solid-state electrolyte synthesis, battery operati

What are the hazards associated with a battery?

These hazards can be associated with the chemicals used in the manufacture of battery cells, stored electrical energy, and hazards created during thermal runaway, (see below) which can include fire, explosions, and chemical byproducts.

Are batteries safe?

However, batteries are both difficult to produce at the gigawatt-hour scale and sensitive to minor manufacturing variation. As a result, the battery industry has already experienced both highly-visible safety incidents and under-the-radar reliability issues—a trend that will only worsen if left unaddressed.

How to reduce the safety risk associated with large battery systems?

To reduce the safety risk associated with large battery systems, it is imperative to consider and test the safety at all levels, from the cell level through module and battery level and all the way to the system level, to ensure that all the safety controls of the system work as expected.

What are some high-profile safety events involving lithium-ion batteries?

Indeed, since the commercialization of lithium-ion battery technology in 1991 7, 8, several high-profile safety events (Fig. 1a) have occurred in sectors such as consumer electronics, electric micromobility, EVs, aviation, and medical devices 9, 10. One infamous EV safety case required a USD $1.9B fleetwide recall 11, 12.
