摘要： A lithium-ion battery having at least an anode that includes phenol formaldehyde in a range of 0.1% to 10% by weight as a binder material. The phenol formaldehyde, or a mixture of phenol formaldehyde with polyvinylidene fluoride (PVDF), is used as a binding material in a Li-ion battery negative electrode to decrease the exothermic reaction of the battery during charging and discharging, which accordingly lessens the risk of thermal runaway and rupture of the battery.
