Latest Patents
Fujino holds a patent for an anode and battery, along with the manufacturing methods thereof. This invention focuses on realizing high capacity and improving charge and discharge cycle characteristics. The anode active material layer consists of a particulate anode active material that includes a simple substance or a compound of an element capable of forming an alloy with lithium. Additionally, it incorporates a particulate binder made from a copolymer of vinylidene fluoride or polyvinylidene fluoride, along with a conductive agent. The manufacturing process utilizes a dispersion medium with a swelling degree of 10% or less to the binder, specifically pure water. This innovative approach allows the particulate binder to function as a cushion, absorbing the expansion and shrinkage of the anode active material during charge and discharge cycles. This design prevents the lowering of electron conductivity caused by cracks or separation, ensuring that the electrode reaction is performed effectively.
