Recycled materials have traditionally been considered inferior to virgin materials and only applied to low-value applications. If true, this would make them unsuitable for new battery production. In this section, we discuss how recycled materials can be reintroduced into new batteries.

The rapid increase in lithium-ion battery (LIB) production has escalated the need for efficient recycling processes to manage the expected surge in end-of-life batteries. Recycling methods such as direct recycling could decrease recycling costs by 40% and lower the environmental impact of secondary pollution.

In direct recycling, the cathode materials are processed without breaking down their crystal structure. Spent batteries are first manually disassembled and separated into different parts (Fig. 3a), and the cathode materials are subsequently recovered through a relithiation process 92.

Because batteries are in principle infinitely recyclable, the level of coating or doping elements can reach a threshold and result in recovered materials with inferior performance 95, 221, 222, 223.

s risks and ensure systems are properly recovered for recycling. Batteries may contain harmful and dangerous materials such acid, lithium, or heavy metals such as cadmium, cobalt, and lead. Batteries that require disposal must be stored safely in a cool, dry place o the reach of children and with any exposed ter
