Is intercalation a synergy in a single battery material?

Exploiting the synergy between intercalation and conversion reactions in a single battery material seems to be an emerging trend. We develop, herein, a primitive physicochemical model to understand the basic features of this new kind of battery material.

What are the different types of rechargeable battery materials?

Rechargeable battery materials are often categorized into intercalation (or insertion) and conversion (or displacement) types. Quintessential examples of the former category include graphite and lithium cobalt oxide (LiCoO x ), the anode and cathode material, respectively, in the most common lithium-ion batteries in the market.

What are conversion-type cathodes?

Conversion-type cathode materials are some of the key candidates for the next-generation of rechargeable Li and Li-ion batteries. Continuous rapid progress in performance improvements of such cathodes is essential to utilize them in future applications.

Can a failed cathode material be converted into a catalyst?

The transformation and modification strategies of failed cathode material toward catalysts are summarized and analyzed. Applications of spent LIB cathode material-derived catalystsin electrocatalysis are demonstrated. Key challenges and countermeasures in conversion of failed cathode materials into catalysts are identified and suggested.

Can regenerated cathode materials be converted into higher value-added products?

At the same time, with the further exploration of the spent LIB recycling technology, besides the reuse in LIBs as regenerated cathode materials, whether the spent cathode material can be converted into higher value-added products has become a problem worth considering.

How to convert ternary cathode material into OER/Orr bi-functional catalyst?

For example, Zhou et al. reported a fast thermal radiation method for converting a spent ternary cathode material (NCM523) into an efficient OER/ORR bi-functional catalyst. As shown in Fig. 7 a, the spent NMC cathode material was collected and dissolved into nitric acid to obtain a mixed NiMnCo solution.
