Abstract

Abstract : Almost every person is using batteries on daily base. From small appliances to larger power tools to large stores and electric cars. Requirements for lithium ion batteries getting higher every year either from view of capacity, cycle number, or high current flow. With higher requirements is also the safety of batteries connected. Lithium ion batteries need to work safely and reliably at higher temperatures and loads. From flame safety view is necessary non-flammability of all battery parts. One of potential risk is organic solvents based electrolyte. This paper focus on influence, of flame-retardant additive in electrolyte, and its compatibility with the negative electrode in lithium ion battery. Several phosphorous-based flame retardants were tested and their influence on capacity of negative electrode was determined.
