Finally, the future industrial development of sodium-ion solid-state batteries is prospected. Sodium-ion batteries have abundant sources of raw materials, uniform geographical distribution, and low cost, and it is considered an important substitute for lithium-ion batteries.
The development of functional sodium-containing solid-state batteries (SSBs) depends on advancing solid-state electrolyte (SSE) materials with high ionic conductivity and exceptional chemical-electrochemical stability, which continues to pose significant challenges.
This limitation significantly restricts the energy density of sodium solid-state batteries. Clearly, overcoming the high-voltage stability issue of sodium sulfide solid-state electrolytes is a critical challenge for their commercialization. 5.

Dendrites, whose name comes from the Latin for branches, are projections of metal that can build up on the lithium surface and penetrate into the solid electrolyte, eventually crossing from one electrode to the other and shorting out the battery cell.. Dendrites, whose name comes from the Latin for branches, are projections of metal that can build up on the lithium surface and penetrate into the solid electrolyte, eventually crossing from one electrode to the other and shorting out the battery cell.. All-solid-state batteries ofer high-energy-density and eco-friendly energy storage but face commercial hurdles due to dendrite formation, especially with lithium metal anodes. Here we report that dendrite formation in Li/Li7La3Zr2O12/Li batteries occurs via two distinct mechanisms, using. . Researchers solved a problem facing solid-state lithium batteries, which can be shorted out by metal filaments called dendrites that cross the gap between metal electrodes. They found that applying a compression force across a solid electrolyte material (gray disk) caused the dendrite (dark line at. [pdf]

The impact of pressure on battery performance has two sides: appropriate pressure can ensure close contact between various components of the battery, prevent poor electrode interface contact, and improve the deposition mode of lithium ions, thereby enhancing the cycling stability of the battery..

October 9, 2024 | A common concern with solid-state batteries is the need to maintain tight contacts between layers, as there is no liquid that can access voids and ensure conductivity; volume changes associated with lithium deposition further compound this issue. A common solution is the. . They found that applying a compression force across a solid electrolyte material [gray disk] caused the dendrite [dark line at left] to stop moving from one electrode toward the other [the round metallic patches at each side] and instead veer harmlessly sideways, toward the direction of the force.

SSLB, solid-state lithium metal battery. From the engineering point of view, the target stack pressure values should be ideally <0.1 MPa (a few MPa may also be technically acceptable) to meet industrial-scale production requirements 126, whereas the stack pressure in most current SSLB studies (>10 MPa) is much higher than this.
The development of solid-state batteries has encountered a number of problems due to the complex interfacial contact conditions between lithium (Li) metal and solid electrolytes (SEs). Recent experiments have shown that applying stack pressure can ameliorate these problems.
Particularly, a pressure of at least 3 kPa is required for a better contact for a current of 0.1 mA/cm 2, while at least 1 MPa pressure is needed to improve the interface under a current of 2.0 mA/cm 2. The guiding principles disclosed here may prove beneficial for the development of future solid-state batteries.
They studied the effect of pressure on the growth of lithium dendrites in solid-state lithium symmetric batteries. It was found that at a pressure of 110 kPa, a large number of lithium dendrites formed, and more porous structures appeared on the lithium electrode after cycling.

Solid-state lithium-ion batteries promise to be more safe, lightweight, and compact than their conventional counterparts. However, metal spikes can grow inside them, leading to short-circuit breakdowns. Now a new study finds that applying pressure on these batteries may be a simple way to prevent such failures.
