    • The invention is directed to an SVO electrochemical cell having high rate capability. The cathode is produced by coating a mixture of an active material, conductive additives, a mixed binder, and an aluminum foil current collector. The mixed binder consists of a mixture of styrene butadiene with PVDF. The use of the styrene butadiene maintains adhesion to the conductive current collector while the PVDF portion of the binder gives flexibility. A particularly preferred couple is of a lithium/silver vanadium oxide (Li/SVO) chemistry and the binder mixture enables an active slurry of SVO to be coated onto a current collector without delamination.
    • 本发明涉及具有高速率能力的SVO电化学电池。 通过涂覆活性材料,导电添加剂,混合粘合剂和铝箔集电体的混合物来制造阴极。 混合的粘合剂由苯乙烯丁二烯与PVDF的混合物组成。 苯乙烯丁二烯的使用保持与导电集电体的粘附性,而粘合剂的PVDF部分具有柔性。 特别优选的一对是锂/银钒氧化物(Li / SVO)化学,并且粘合剂混合物使SVO的活性浆料能够涂覆在集电器上而不会分层。
