Peltier effects in lithium-ion battery modeling

چکیده

A high battery temperature has been shown to be critical for lithium-ion batteries in terms of performance, degradation, and safety. Therefore, a precise knowledge heat sources sinks the is essential. We have developed thermal model batteries, that includes not included before, namely, Peltier Dufour effects. The derived using non-equilibrium thermodynamics heterogeneous systems, only theory which able describe systematic manner coupling heat, mass, charge transport. idea this deal with surfaces as two-dimensional layers. All electrochemical processes these layers are defined excess variables, implying, instance, surface its own temperature. show how heats affect single cell may produce an internal rise 8.5 K stack 80 modules. fluxes leaving also functions reversible Most energy dissipated occurs electrode electrolyte-filled separator. analysis shows better experimental data on resistances, transport coefficients, essential further progress modeling important class systems.

Electrochemical Characterization of Low-Cost Lithium-Iron Orthosilicate Samples as Cathode Materials of Lithium-Ion Battery

Lithium-iron-orthosilicate is one of the most promising cathode materials for Li-ion batteries due to its safety, environmental brightness and potentially low cost. In order to produce a low cost cathode material, Li2FeSiO4/C samples are synthesized via sol-gel (SG; one sample) and solid state (SS; two samples with different carbon content), starting from Fe (III) in the raw materials (lo...
