LITHIUM ION BATTERY

摘要

The present invention relates to a lithium ion battery, comprising a positive electrode, a negative electrode, a separator and an electrolyte solution, the positive electrode comprising a positive electrode active substance, a conductive agent and a positive electrode binder, the positive electrode binder being a polymer obtained via a polymerisation reaction of an organic diamine-type compound and maleimide-type monomers, the maleimide-type monomers comprising at least one of maleimide monomers, bismaleimide monomers, polymaleimide monomers and maleimide-type derivative monomers.
