Features of fast charging of lithium-ion batteries: electrochemical aspects (mini-review)

The problem of fast charging of lithium-ion batteries is one of the key problems for the development of electric transport. This problem is multidisciplinary and is connected, on the one hand, with electrochemical current-producing processes and the features of lithium-ion batteries themselves, and on the other hand, with the charging infrastructure, the design of chargers, charging protocols, thermal management, battery management systems, etc. This review concerns the electrochemical aspects of fast charging keeping in mind that lithium-ion battery is a complicated and delicate system. Problems associated with positive and negative electrodes and electrolyte are considered separately.
