6 FAQs about [Dissolution of Lithium-ion Battery Electrode Materials]

Is manganese dissolution a problem in lithium ion battery electrolyte?

Manganese dissolution in lithium-ion battery electrolyte is a well known problem and widely documented for the spinel LiMn 2 O 4, , , , , , , , , , , however studies of similar processes for LiFe 1−x Mn x PO 4 are scarce , , .

How does electrode material aging affect the performance of lithium-ion batteries?

They are also grateful to all of the anonymous reviewers for providing useful comments and suggestions that resulted in the improved quality of this paper. Electrode material aging leads to a decrease in capacity and/or a rise in resistance of the whole cell and thus can dramatically affect the performance of lithium-ion batteries.

Does the identity of lithium salt anions affect the dissolution process?

We find that the identity of the lithium salt anions in our electrolyte systems [ClO 4–, PF 6–, and (CF 3 SO 2) 2 N –] appears to affect the Mn dissolution process significantly as well as the electrochemical behavior of the generated Mn complexes.

Can electrode materials make Li-ion batteries smaller?

A great volume of research in Li-ion batteries has thus far been in electrode materials. Electrodes with higher rate capability, higher charge capacity, and (for cathodes) sufficiently high voltage can improve the energy and power densities of Li batteries and make them smaller and cheaper.

What makes a lithium ion battery a cathode?

Unlike the revolutionary advances in the anodes of lithium-ion batteries from Li intercalation materials to Li alloy and/or conversion reaction materials, the development of the cathode is still dominated by the Li intercalation compounds.

Why do lithium ion batteries have fracture and decrepitation?

Fracture and decrepitation of the electrodes are critical challenges existing in lithium-ion batteries as a result of lithium diffusion during the charging and discharging operations. When lithium ions intercalate and deintercalate into/from the graphite electrode, a large volume change on the order of a few to several hundred percent can occur.
