“…The electrolyte kept its original color after 100 krad exposure, but after 700 krad and 2.7 Mrad it changed its color due to its decomposition. Another study, this time on both a cathode (LiFePO4) and electrolyte, was carried out by Tan's group [39]. They revealed that both components contribute to the capacity loss after heavy radiation (26.7% loss at 9.8 Mrad of the irradiated cathode, 11.2% loss at 5.7 Mrad of the irradiated electrolyte), as shown in Figure 4c.…”

A Review of Battery Technology in CubeSats and Small Satellite Solutions

CubeSats and small satellite solutions are increasing in popularity as they enable a fast, cheap, and agile way for satellite applications. An essential component of nearly every satellite is the energy storage device, which is practically equal to a battery. Consequently, an overview of past, present, and future battery technologies for CubeSats is presented. CubeSats use typically commercial off-the-shelf (COTS) batteries. They are not primarily dedicated to space, so their suitability to the space environment needs to be evaluated. Batteries are also considered as potentially dangerous goods. Thus, there are guidelines and standards that specify safety criteria and tests for the batteries in order to be allowed for transportation and launch. Furthermore, the character of satellites’ missions determines their demand on batteries in terms of current rates, depth-of-discharge, and lifetime. Thus, these expectations are discussed. A market survey was also carried out to identify currently available commercial battery solutions and their parameters. This work summarizes the status, requirements, and the market situation of batteries for CubeSats.

Modular Multifunctional Composite Structure for CubeSat Applications: Preliminary Design and Structural Analysis

et al. 2020

CubeSats usually adopt aluminum alloys for primary structures, and a number of studies exist on Carbon Fiber Reinforced Plastic (CFRP) primary structures. The internal volume of a spacecraft is usually occupied by battery arrays, reducing the volume available to the payload. In this paper, a CFRP structural/battery array configuration has been designed in order to integrate the electrical power system with the spacecraft bus primary structure. The configuration has been designed according to the modular design philosophy introduced in the AraMiS project. The structure fits on an external face of a 1U CubeSat. Its external side houses two solar cells and the opposite side houses power system circuitry. An innovative cellular structure concept has been adopted and a set of commercial LiPo batteries has been embedded between two CFRP panels and spaced out with CFRP ribs. Compatibility with launch mechanical loads and vibrations has been shown with a finite element analysis. The results suggest that, even with a low degree of structural integration applied to a composite structural battery, more volume and mass can be made available for the payload, with respect to traditional, functionally separated structures employing aluminum alloy. The low degree of integration is introduced to allow the use of relatively cheap and commercial-off-the-shelf components.

“…Based on previous studies [20,59], the slip shear stress t y is associated with dislocations and defect densities. For a single crystal, a rate-independent yield function, F(s, t y ) [14,26,[28][29][30][31][32]36,60] can be written as…”

“…During deep space exploration, however, LIBs suffer severe irradiation effects, high radiation field and post-nuclear accident scenario [28][29][30][31][32]. Qiu et al [33] and Samin et al [34] characterised the surface morphologies of cathode materials before and after neutron and gamma-ray irradiation with a growing particle size and reported that irradiation causes disordering of crystal structures in a post-irradiation sample, which further results in capacity loss of batteries.…”

Deterioration was detected because of the irradiation effect on electrode and electrolyte materials [32]. Recently, Ma et al [35] developed an electrochemical-irradiated plasticity model to study the effects of irradiation and diffusion-induced stress on the mechanical properties of cylindrical electrodes, and showed that the yield strength of irradiated electrode materials increases with dose.…”

A constitutive model coupling irradiation with two-phase lithiation for lithium-ion battery electrodes

When lithium-ion batteries serve in extreme environments like space, severe irradiation might induce significant decay of the electrochemical performances and mechanical properties. In this paper, an electrochemical-irradiated constitutive model is proposed to explore the evolution of dislocation, defect and stress in electrodes during a twophase lithiation process. The results from the analytic formulation and finite difference calculations show that, as Li intercalation proceeding, the hoop stress in the surface of a spherical particle converts from compression into tension because the large lithiation strain and plastic yielding at the front pushes out the material behind it. And the plastic flow resistance continuously increases with increasing irradiation dose result from the impediment of a defect to dislocation glide. There is a clear peak in the distribution of stress at yielding locations due to the competition between dislocations multiplication and defects annihilation. The model is meaningful for thoroughly understanding the micro-mechanism of lithiation deformation and provides a guideline for predicting their mechanical behaviours of lithium-ion batteries in unconventional environment.
