The field of new energy batteries is a major national strategy and a hot spot for research and development. Particular attention is paid to battery technology and electrode materials. In recent years, the importance of electrolytes has become increasingly prominent, but there is still a long way to go for practitioners to train in this field, mainly due to their lack of knowledge and technology. It is in this context that the book was planned and designed. The main feature and advantage of the book is that the author combines academic and practical work according to his own industry and scientific research experience, which is also an important advantage of the book. It is expected that this book will have important guiding value for graduate students in the field of electrochemistry in universities and technicians in battery companies.The translation was done with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content.
