Battery electrochemist and materials researcher

Aswadh Shyma Sajeevan

From redox-active materials and composite electrodes to solid polymer electrolyte cells and electrochemical diagnosis.

I develop battery materials, integrate them into working cells and investigate why their practical performance differs from their theoretical potential. My work connects active-material synthesis, carbon and binder selection, composite-electrode processing, solid polymer electrolytes, lithium-metal cells, electrochemical testing and post-mortem analysis.

I completed my PhD in Materials Science at Institut des Matériaux de Nantes Jean Rouxel, Nantes Université-CNRS, in February 2026 as a Marie Skłodowska-Curie DESTINY fellow.

About

My doctoral research focused on batteries that combine lithiated organic positive electrode materials with solid polymer electrolytes. Instead of treating the electrolyte membrane and composite electrode as separate components, I investigated how their chemistries and processing conditions could be integrated. The same PCL-PTMC polyester-polycarbonate chemistry was used as both the electrolyte matrix and the binder within the positive electrode, making the binder part of the ion-transport pathway rather than inert glue. The electrodes were formulated without PVDF or NMP.

My work follows the battery-development chain from materials to diagnosis. I have synthesised redox-active compounds, formulated free-standing polymer electrolyte membranes, prepared composite electrodes, assembled lithium-metal cells and developed testing protocols. I use impedance, polarisation, Coulombic efficiency, rate behaviour and post-mortem characterisation to determine whether performance is limited by redox chemistry, electronic transport, ionic transport, interfacial contact or material dissolution.

New to batteries? How batteries work is my free, interactive course on lithium-ion batteries. Its chapters run from electric field and potential and cell voltage to the solid electrolyte interphase, degradation and recycling, and its lab handbook covers cyclic voltammetry, GITT and impedance spectroscopy. Every statement is checked against a textbook or a peer-reviewed article and every figure is computed from its source.

Before and alongside my doctoral work, I contributed to lithium-ion and sodium-ion electrode materials, silicon-based composites derived from kaolin, graphene-metal-oxide composites prepared from waste precursors, micro-coaxial battery architectures, porous and chemically modified carbon materials, polymeric organic electrodes, LiCoO₂ upcycling and thin-film devices. I am interested in research and development roles in Europe involving solid-state batteries, polymer electrolytes, electrode processing, organic electrodes, electrochemical testing and battery-material recovery.

Featured research

Four pieces of work that show how I move from a material to a diagnosis.

Integrating the polymer electrolyte and positive electrode

Doctoral research, Institut des Matériaux de Nantes Jean Rouxel, Nantes Université-CNRS

I combined lithiated organic positive electrode materials with PCL-PTMC/LiTFSI solid polymer electrolytes. The same copolymer chemistry was used inside the positive electrode as a functional binder and as the free-standing electrolyte membrane, removing a chemical discontinuity at the electrode-electrolyte boundary.

Thermal preconditioning of the assembled cell increased the reversible utilisation of the active material. Within the investigated cell design, this indicated that interfacial contact and ionic access within the composite electrode were more restrictive than the intrinsic redox chemistry.

Contact, not theoretical capacity, was the principal bottleneck in this cell configuration.

Accessing a second electron through electrode architecture

Doctoral research, published in ChemSusChem

The copper-based lithiated organic positive electrode material Cu(Li₂)-p-DHT is theoretically capable of a two-electron oxidation. However, conventional mechanical mixing with conductive carbon provided limited utilisation.

I designed an in situ synthesis that formed the active material directly in the presence of Ketjenblack. At equal carbon content, this carbon-supported architecture increased delivered capacity from approximately 56 to 188.2 mAh g⁻¹, approaching complete two-electron oxidation.

FTIR, ICP-AES and STEM-EELS, with the microscopy performed through collaboration, were used to investigate the resulting material and its degradation. The analysis indicated that the fully oxidised state was at least partially soluble, limiting sustained two-electron cycling. Restricting operation to the first redox process produced approximately 96 % capacity retention over 50 cycles, Coulombic efficiencies above 99 % and capacities close to 80 mAh g⁻¹.

The initially missing second electron was an electrode-architecture problem, while its long-term retention was limited by the stability of the oxidised material.

Polymer electrolyte membranes and their operation inside cells

DESTINY secondments, Ångström Laboratory, Uppsala University

I formulated PCL-PTMC/LiTFSI solid polymer electrolyte membranes by solution casting and hot pressing, producing free-standing films. Their thermal, chemical and electrochemical behaviour was investigated using TGA-DSC, ATR-FTIR, linear sweep voltammetry and impedance spectroscopy in blocking-electrode cells.

I fitted impedance spectra using equivalent circuits and evaluated temperature-dependent conductivity through Vogel-Tammann-Fulcher analysis. I also contributed hands-on to the group's established ring-opening copolymerisation procedure.

The more difficult challenge appeared during cell integration: handling and aligning the membranes, maintaining electrode-electrolyte contact and applying controlled clamp-assisted pressure. This work included laboratory cell configurations and pouch-cell assembly.

A polymer electrolyte membrane is only as useful as the interfacial contact it maintains inside the complete cell.

Recovery of an organic active-material precursor after cycling

Doctoral research, manuscript in preparation

Organic electrode materials are frequently described as potentially recyclable, but recovery after electrochemical cycling is rarely demonstrated experimentally.

I developed a mild chemical approach for recovering an organic active-material precursor from cycled lithiated organic positive electrode material. The process also enabled separation of lithium- and metal-containing inorganic streams and informed a component-wise recovery strategy for the remaining cell constituents.

Recyclability should be demonstrated using cycled material, not assumed from molecular structure alone.

Additional research projects

Spectator-cation effects in lithiated organic electrodes

Investigated how Mg, Zn and Cu centres influence the structure, redox behaviour, capacity utilisation and cycling stability of lithiated organic positive electrode materials. Methods included materials synthesis, structural and spectroscopic analysis, composite-electrode formulation, galvanostatic cycling, cyclic voltammetry, impedance spectroscopy and post-mortem investigation.

ORGANION collaborative research

Contributed to the ANR-DFG ORGANION collaboration involving Nantes and Prof. Birgit Esser's group in Germany. The project examined organic and polymeric electrode materials for more sustainable battery chemistries. My contribution included electrochemical evaluation, electrode processing, interpretation of cycling behaviour and collaboration across complementary synthesis and characterisation teams.

Super-electron-donor polymers for organic batteries

Contributed to the electrochemical investigation of bridged bipyridinium-based super-electron-donor polymers designed as low-potential p-type electrode materials for organic batteries. The work connected polymer design, redox energetics, composite-electrode formulation and battery testing.

Porous and chemically modified carbon materials

Prepared and evaluated carbon materials, including acid-activated and heteroatom-doped Ketjenblack for electrocatalysis and a porous carbon for polymer-electrode composites, with attention to pore structure, surface chemistry and electrical conductivity. This experience underpins my later work on conductive-carbon selection and active-material distribution within composite electrodes.

Silicon-based electrodes from kaolin-derived precursors

Developed silicon-containing electrode materials prepared from kaolin-derived sources for lithium-ion battery applications, in an industry-linked project spanning precursor conversion, composite formation, materials characterisation, electrode preparation and electrochemical evaluation.

Graphene-metal-oxide composites from waste-derived precursors

Worked on graphene-based metal-oxide composites prepared using waste-derived starting materials for electrochemical energy-storage applications, combining resource recovery, functional-material synthesis and electrochemical testing.

Micro-coaxial battery architectures

Fabricated micro-coaxial battery configurations using aligned Cu/Ni nanorod current collectors and coaxial Cu₂MoS₄ electrodes. This work introduced me to architecture-driven battery design, small-scale electrode integration and the relationship between cell geometry and electrochemical performance.

Acid-free upcycling of LiCoO₂

Led research on upcycling spent LiCoO₂ into a bifunctional CoMoS₄ water-splitting catalyst without conventional strong-acid processing. The project strengthened my interest in battery-material circularity and in recovery routes that preserve more of a material's embedded value.

Thin-film device research

Completed a research internship on thin-film device fabrication and characterisation at the Indian Institute of Science, Bangalore, including reactive magnetron sputtering, evaporation, device handling and electrical characterisation.
