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.

摘要： A method for making a coated electrode material for a lithium rechargeable electrochemical cell (10) includes the steps of mixing (65) Co and Li salts, then either dissolving (70) the Li and Co salts in water to form a solution or heating (70) the salts to form a melt. A lithium nickel oxide material is mixed (80) with the solution or the melt to form a mixture, and the mixture is dried (85) to result in LiCoO.sub.2 -coated LiNiO.sub.2. Increased performance can be achieved by including a post-treatment step in which the LiCoO.sub.2 -coated LiNiO.sub.2 is heated (90) to about 700.degree. C.
