Researchers at Penn State have innovated a new method to improve the recycling of solid-state lithium batteries.<\/h2>\n

The team has reconfigured the design of solid-state lithium batteries<\/a> so that all of their components can be recycled efficiently.<\/p>\n

Rechargeable solid-state lithium batteries are a disruptive technology in the battery sector that could one-day power consumer electronics with a single charge.<\/p>\n

These batteries offer greater energy density than traditional lithium-ion batteries; however, recycling them is a major challenge.<\/p>\n

Current recycling methods focus on the limited recovery of metals in the cathodes, with the rest ending up as battery waste<\/a>.<\/p>\n

The leader of the study, Enrique Gomez, believes the team’s innovation could prove pivotal in improving recyclability.<\/p>\n

He explained: “As the need for rechargeable batteries grows, we need to think about the end-of-life of this technology.<\/p>\n

“We hope our work highlights the possibilities in recycling solid-state batteries, with the help of some key design elements.”<\/p>\n

Simplifying battery recycling<\/h3>\n

Recycling battery components<\/a> typically results in a “black mass,” a mixture of valuable materials that are hard to separate.<\/p>\n

Solid-state batteries exacerbate this issue as their solid electrolytes mix with the black mass during the recycling process.<\/p>\n

Innovative polymer layer solution<\/h3>\n

To overcome this issue, the researchers inserted polymer layers between the electrode and electrolyte of coin cell batteries to simplify the recycling process.<\/p>\n

These layers dissolve during recycling, allowing easy separation of the electrode from the electrolyte.<\/p>\n

“We proposed that by dissolving the polymer layer during the recycling process, you can easily separate the electrode from the electrolyte,” said Yi-Chen Lan, doctoral student in chemical engineering and first author of the paper.<\/p>\n

“Without the polymer layer separating them, you would have the electrode and electrolyte mixed together, which makes them hard to recycle.”<\/p>\n

Using cold sintering, a method developed at Penn State, the team created a composite from the recovered materials.<\/p>\n

This approach enabled the reconstruction and subsequent re-recycling of the entire battery.<\/p>\n

Promising results<\/h3>\n

The recycled battery retained 92.5%-93.8% of its original capacity. While commercial use of all-solid-state lithium batteries is still developing, this research paves the way for designing recyclable batteries for future applications in devices like phones and laptops.<\/p>\n","protected":false},"excerpt":{"rendered":"
