An embedded tab bulge and plate recess strengthen the battery cell connection, improving conductivity and resisting fatigue from electrode expansion.
Optimized electrode pore size and electrolyte viscosity improve liquid retention and flowback, reducing lithium plating in large batteries.
Alternating convex and non-convex electrode regions keep porosity balanced, boosting capacity retention while avoiding mold changes.
Continuous slurry coating and cutting removes binders from battery electrodes, simplifying production while improving conductivity and capacity.
A carbon-nanofiber-coated graphite anode cuts side reactions and diffusion resistance to improve rapid charging and battery lifespan.
An organic-inorganic composite layer built into the negative electrode suppresses lithium dendrites and side reactions while improving thermal stability.
Two-stage pressure leaching plus selective zinc and magnesium extraction improves nickel, cobalt, and manganese recovery with lower solvent cost.
Uneven electrode thinning near a tab groove is addressed by asymmetric adhesive coverage that fully seals the groove while lowering lithium plating risk.
