摘要:
An object of the present invention is to provide composite particles for an electrochemical device electrode capable of preparing an electrode having high thickness precision at a low basis weight, an electrochemical device electrode and an electrochemical device that use the composite particles for an electrochemical device electrode, and to provide a method for manufacturing the composite particles for an electrochemical device electrode, and a method for manufacturing the electrochemical device electrode.The present invention relates to composite particles for an electrochemical device electrode that are obtained by spray-drying a slurry containing an electrode active material and a binder resin, in which particles of 40 μm or less are 50% or less of an entire amount in a number-based particle size distribution obtained by particle size measurement using a laser light diffraction method and the cumulative 95% size (D95 size) is 300 μm or less in a volume-based particle size distribution.
摘要:
The present invention relates to a method for manufacturing a binder composition for a lithium-ion secondary battery electrode. The method comprises a step of dissolving a polymer having a melting point in a range of 50° C. to 150° C. in a monomer and obtaining a monomer solution in which the polymer is dissolved in the monomer; and a step of obtaining a composite polymer particle by subjecting the monomer solution to suspension polymerization or emulsion polymerization in an aqueous medium. The binder composition contains the composite polymer particle.
摘要:
The present invention relates to a binder composition for lithium-ion secondary battery electrodes. Recently, there is a need for a lithium-ion secondary battery which has the excellent property of accommodating an abnormal situation so that in cases when the battery has heated up abnormally or is in an abnormally high-temperature environment, the battery can lower the charge/discharge performance thereof. The present invention solves the above-mentioned problem by using, as a binder for electrodes, composite polymer particles obtained by polymerizing, in an aqueous medium, a monomer solution containing a polymer.
