TMHD Precursors for Battery & Energy Applications
Halide-free cathode coatings for cycling stability
For battery researchers and engineers developing conformal ALD coatings for cathode protection and solid electrolytes
Your Challenge. Our Answer.
We understand the specific problems you face — and we built solutions for each one.
The Problem
Halide-containing precursors deposit Cl/F contaminants that corrode battery electrodes and degrade cycling performance
Mironova’s Answer
TMHD precursors are entirely halide-free — no Cl or F contamination pathway. Safe for electrode surface chemistry.
The Problem
Precursor thermal decomposition in fluidized-bed or rotary reactors causes non-uniform coatings on powder substrates
Mironova’s Answer
TMHD’s exceptional thermal stability enables predictable dosing even in demanding powder-coating reactor environments
Published Evidence
Key findings from peer-reviewed literature relevant to your application.
ALD for Battery Cathodes
ALD coatings on cathode powders (NMC, LFP) improve cycling stability by preventing surface degradation. Ultra-high precursor purity is critical for electrochemical stability.
Meng et al., Adv. Mater. 2012
Halide-Free Precursor Advantage
Residual halides from precursors (e.g. HfCl₄) act as charge traps and contamination sources in thin films. Halide-free TMHD precursors eliminate this risk at the molecular level.

Battery ALD Guidelines
- Coating thickness: 0.5–5 nm (submonolayer to few nm)
- Application: fluidized-bed ALD or rotary reactor
- Electronic-grade purity required for long-term cycling
- Ozone (O₃) required as oxidant for all TMHD precursors
