Rechargeable lithium batteries having an ultra-high volumetric energy density and required production process

摘要

A process for producing a lithium battery, comprising: (A) Assembling a porous cell framework composed of a foamed anode current collector, a foamed cathode current collector, and a porous separator disposed between the two collectors; wherein the current collector(s) has a thickness no less than 100 μm and at least 80% by volume of pores; (B) Preparing a first suspension of an anode active material dispersed in a first liquid electrolyte and a second suspension of a cathode active material dispersed in a second liquid electrolyte; and (C) Injecting the first suspension into pores of the anode current collector to form an anode and injecting the second suspension into pores of the cathode current collector to form a cathode to an extent that the anode active material and the cathode active material combined constitutes an electrode active material mass loading no less than 40% of the total battery cell weight.
