リチウムイオン電池の極板材料
Document Type and Number:
Japanese Patent JP7368423
Kind Code:
B2
Abstract:
An electrode material of a lithium-ion battery is provided. The electrode material of the lithium-ion battery has 5 to 70 parts by weight of unbuffered active material; and 30 to 95 parts by weight of buffered active material. By adding a specific proportion of a buffered material (such as the graphite material particles), the electrode material of the lithium-ion battery avoids or reduces breakage or cracking of the unbuffered active material themselves or the shell thereof during a rolling step, so a cycle life of a battery can be improved.
