Autonomous Electrode Dissolution Prevention System for Identifying and Suppressing Side Reactions in Lithium-ion Batteries
Koduru Gouthami, Chiluka Ramesh, Snehitha Paruchuri, Sunitha KandepuIntroduction:
Electrode dissolution, electrolyte decomposition, interphase growth, and related side reactions can accelerate capacity loss and resistance growth in lithium-ion batteries. This study evaluates an Autonomous Electrode Dissolution Prevention System (AEDPS) that combines electrical and thermal sensing, model-based state estimation, degradation indicators, and adaptive control.
Methods:
A lithium-ion single-cell proof-of-concept setup was monitored for voltage, current, and temperature. An equivalent-circuit/electrochemical model, Extended Kalman Filter state estimation, and multi-indicator degradation logic were evaluated using the available cycling and simulation records.
Results:
The reported voltage RMSE was 0.01326 V, and the maximum temperature deviation was 0.14998 °C. Internal resistance increased from 0.0500 to 0.0794 Ω, while normalized capacity retention decreased to 92.65% after 50 cycles. The supplied SoC-error trace was near zero; because the underlying raw error series was unavailable, an exact zero-error value is not claimed.
Discussion:
The results support the feasibility of combining degradation-aware diagnostics with closed-loop operating adjustments, but the single-cell dataset, missing replicate statistics, and incomplete archived test metadata limit generalization.
Conclusion:
AEDPS provides a proof-of-concept framework for early degradation awareness and adaptive battery management; broader multi-cell and long-duration validation is required.
