Abstract (en)
[origin: WO2012139742A1] The invention relates to a lithium ion battery comprising: (i) a positive electrode comprising at least a lithium transition metal phosphate having an olivine structure, wherein the transition metal selected is made of manganese, cobalt, nickel, or a mixture of two or three of said elements; (ii) a negative electrode; (iii) a separator that separates the positive and the negative electrode from one another and is permeable to lithium ions; wherein the separator comprises a mat made of non-woven, non-electrically conductive polymer fibres, which is coated with an ion-conducting inorganic material on one side or both sides; (iv) a non-aqueous electrolyte.
