“…The reasons for this difference in behavior between bulk and thin film batteries are not understood. As pointed out in two recent reports, similar short circuit events were investigated in Na‐ion conducting solid electrolytes in liquid Na batteries in the 1970–1980s . In these cases, the short circuit event was attributed to stresses created by molten sodium metal plating into cracks within the solid electrolyte bulk, resulting in crack propagation and eventual failure.…”

“…Only in thin film batteries have Li metal negative electrodes paired with inorganic solid electrolytes (e.g., LiPON) been able to avoid dendrite penetration over extended cycling. [35][36][37][38][39][40][41][42] In these cases, the short circuit event was attributed to stresses created by molten sodium metal plating into cracks within the solid electrolyte bulk, resulting in crack propagation and eventual failure. As pointed out in two recent reports, [33,34] similar short circuit events were investigated in Na-ion conducting solid electrolytes in liquid Na batteries in the 1970-1980s.…”

vast improvements in energy density may be achieved with lithium metal anodes owing to their high gravimetric capacity (3869 mA h g −1 ) and low density (0.534 g cm −3 ). However, adoption of rechargeable lithium metal batteries has been unsuccessful thus far due to safety concerns associated with short circuits that occur when Li dendrites grow through the liquid electrolyte during the charging process. [4][5][6] Although several approaches have reduced dendrite formation, [7][8][9][10] to date the phenomenon has not been avoided under all relevant conditions. Nonflammable inorganic solid electrolytes, paired with Li metal anodes, could result in high energy density yet safe rechargeable lithium batteries. [11][12][13][14][15] As reviewed by Takada, [12] inorganic solid electrolytes have now been widely studied, [16][17][18][19][20] but are not yet commercialized. Monroe and Newman have suggested that dendrite growth during the plating process may be suppressed if the liquid electrolyte is replaced with a Li-ion conducting solid electrolyte of a sufficiently high shear modulus. [21,22] According to this criterion, numerous inorganic solid electrolytes should be able to suppress dendrite formation. However, multiple research groups have recently reported cases where ceramic solid electrolytes paired with a Li metal anode experience a short circuit Li deposition is observed and measured on a solid electrolyte in the vicinity of a metallic current collector. Four types of ion-conducting, inorganic solid electrolytes are tested: Amorphous 70/30 mol% Li 2 S-P 2 S 5 , polycrystalline β-Li 3 PS 4 , and polycrystalline and single-crystalline Li 6 La 3 ZrTaO 12 garnet. The nature of lithium plating depends on the proximity of the current collector to defects such as surface cracks and on the current density. Lithium plating penetrates/infiltrates at defects, but only above a critical current density. Eventually, infiltration results in a short circuit between the current collector and the Li-source (anode). These results do not depend on the electrolytes shear modulus and are thus not consistent with the Monroe-Newman model for "dendrites." The observations suggest that Li-plating in pre-existing flaws produces crack-tip stresses which drive crack propagation, and an electrochemomechanical model of plating-induced Li infiltration is proposed. Lithium short-circuits through solid electrolytes occurs through a fundamentally different process than through liquid electrolytes. The onset of Li infiltration depends on solid-state electrolyte surface morphology, in particular the defect size and density.

“…Historically, as early as batteries were put into the market, scientists have been challenged to design monitoring techniques [17][18][19][20][21][22][23] to determine their SoC, SoH, and state of power (SoP) (chronologically summarized in Fig. 1b).…”

Recent economic and productivity gains of rechargeable batteries have cemented their dominance in energy-intensive societies. With demand soaring, enhancing battery performance through continuous monitoring is essential to limiting their environmental footprint. While some benefits of sensing have been known for a century, the convergence of fiber optic techniques with new battery platforms is poised to change the industry as a wealth of chemical, thermal, and mechanical data will transform the utilization strategies for new and used lithium-ion devices alike. This Review highlights recent advances and associated benefits with a focus on optical sensors that could improve the sustainability of batteries.

“…Usual approaches to monitor batteries in real field conditions encompass thermocouples, thermistors, pressure gauges, [103] and acoustic sensors [104] placed on the cell surface rather than in its inside, together with the development of on-board electrochemical impedance spectroscopy devices. [105,106] To contour such a limitation, today's disruptive vision consists of injecting smart functionalities into the battery via the integration and development of various sensing technologies to transmit information in and out of the cell (Figure 3).…”

With an exponentially growing demand for rechargeable batteries, the development of new ultra‐performant, fully scalable, and sustainable battery technologies and materials must be accelerated. Creating a holistic, closed‐loop infrastructure for materials discovery, manufacturing, and battery testing that utilizes a common data infrastructure and autonomous workflows to bridge big data from all domains of the battery value chain, can pave the way for a transformative reduction in the required time to discovery. By embedding multisensory and self‐healing capabilities in future battery technologies and integrating these with AI and physics‐aware machine learning models capable of predicting the spatio‐temporal evolution of battery materials and interfaces, it will, in time, be possible to identify, predict and prevent potential degradation and failure modes. This will facilitate enhanced battery quality, reliability, and life, for example, by preemptively changing the battery charging conditions or releasing self‐healing additives from the separator membrane, akin to preemptive medicine, and form the basis for inverse design of new battery materials, interfaces, and additives. The large‐scale and long‐term European research initiative BATTERY 2030+ seeks to make this longer‐than ten‐year vision a reality through the development of a versatile and chemistry neutral “Battery Interface Genome—Materials Acceleration Platform” infrastructure (BIG‐MAP).
