“…Limited research exists on the thermal properties of batteries in neural implants, but studies on lithium-ion batteries in automotive applications offer valuable insights. For instance, research on much larger electric vehicle batteries has demonstrated that different geometries significantly influence heat dissipation and internal temperature variations ( Tendera et al, 2022 ; Dubey et al, 2023 ). Such findings suggest that the geometry of the battery could be an important factor in managing thermal risks in neural implants considering the micro scale of the neural environment.…”

As neural implant technologies advance rapidly, a nuanced understanding of their powering mechanisms becomes indispensable, especially given the long-term biocompatibility risks like oxidative stress and inflammation, which can be aggravated by recurrent surgeries, including battery replacements. This review delves into a comprehensive analysis, starting with biocompatibility considerations for both energy storage units and transfer methods. The review focuses on four main mechanisms for powering neural implants: Electromagnetic, Acoustic, Optical, and Direct Connection to the Body. Among these, Electromagnetic Methods include techniques such as Near-Field Communication (RF). Acoustic methods using high-frequency ultrasound offer advantages in power transmission efficiency and multi-node interrogation capabilities. Optical methods, although still in early development, show promising energy transmission efficiencies using Near-Infrared (NIR) light while avoiding electromagnetic interference. Direct connections, while efficient, pose substantial safety risks, including infection and micromotion disturbances within neural tissue. The review employs key metrics such as specific absorption rate (SAR) and energy transfer efficiency for a nuanced evaluation of these methods. It also discusses recent innovations like the Sectored-Multi Ring Ultrasonic Transducer (S-MRUT), Stentrode, and Neural Dust. Ultimately, this review aims to help researchers, clinicians, and engineers better understand the challenges of and potentially create new solutions for powering neural implants.

“…In all-solid-state batteries, active material geometry influences the tortuosity of the ion transport channel like fuel cells [52,54], with composition and shape having a substantial impact on ion transport parameters. Modifying the geometry of batteries, including size and shape, influences thermal performance [51], with cooling performance diminishing owing to their geometrical arrangement, similar to solid oxide fuel cells [55][56][57].…”

The demand for newer, lighter, and smaller batteries with longer lifespans, higher energy densities, and generally improved overall battery performance has gone up along with the need for electric vehicles. Alternatives must be found because lithium sources are limited and the metal is expensive. Aligned with this, efforts are being carried out to enhance the battery performance of electric vehicles and have shown promise in allaying consumer concerns about range anxiety and safety. This demonstrates that the electric car market will remain very dynamic in the coming decades, with costs continuing to fall. However, developing advanced energy storage technologies from more abundant resources that are cheaper and safer than lithium-ion batteries is a viable option for future mobility and product sustainability. This paper recapitulates the current state of multivalent particularly zinc and iron metal-air battery applications for electric mobility. The cycle capability, range, costs, service life, safety, discharge, and charging rate are all investigated. Factors hampering the further development and marketing of these technologies in connection with possible solutions are also conferred.

Elevated battery temperature and its heterogeneity are responsible for many battery‐related problems such as short lifespan and thermal runaway. For longer life and safe functionality of lithium‐ion battery (LIB), both the average battery temperature and temperature heterogeneity must be controlled. The present work analyzes a modified cooling channel design that can control both the average battery temperature and its heterogeneity. The design adopts microtexturing approach for the heat transfer augmentation of the serpentine cooling channels. First, the transient thermal analysis of different geometry of microtextures, viz., microchannels (MCs) and microdimples (MDs), is carried out on an aluminum slab. The rectangular MCs and square MDs are found to be the most efficient among the other considered microtexture geometries. Further, the modified design is employed for a 19‐cell battery pack to analyze the thermal performance, pressure drop, and coolant pump power requirements. A decrease in maximum temperature difference (MTD) by 6.03 % and 3.72% is observed for 380 MCs (rectangular) and 960 MDs (squared), respectively. While MDs improve the temperature homogeneity within the LIBs, the coolant pump power requirement and pressure drop (by ≈15.42%) are higher for it compared to the MC‐based design for a given MTD.
