“…A new voltage plateau near 4.8V was observed in all cases. The involvement of Li20 and LiC1 in the electrochemical reactions on the positive electrode in l~thium chlorate was explored by chemical analysis for LiC1 and Li20 (5). The lithium chlorate melt surrounding the positive electrode was sampled periodically while discharging at a voltage around 2.5V.…”

“…The diffusion coefficient of Li20 in molten lithium chlorate can be estimated using Levich's equation ( 9) (see Eq. [5]) where IL is the limiting Current; F is the Faraday constant; A is the disk area; D is the diffusion coefficient of Li20; v is the kinematic viscosity of the electrolyte; ~ is the angular velocity of the disk; and C is the concentration of Li20. The n is equal to 2 in this case since two electrons are given up by each Li20 molecule during its reduction.…”

“…Therefore, the solubility of Li20 in lithium chlorate can be evaluated from Eq. [5] to be 7.5 X 10 -~ mol/cm a using an average diffusion coefficient of Li~.O of 1.48 X 10-7 cm2/sec. From Fig.…”

Lithium chlorate, LiC10~, has reported melting points of 127.6 ~ and 129oC. The specific conductance of molten lithium chlorate at 130~ is relatively high compared to common aqueous electrolytic solutions at room temperature. Therefore, lithium chlorate offers the chance to operate a new lithium battery system at a temperature between 130 ~ and 150~ It was found experimentally that lithium chlorate is stable in the potential range between 3.2 and 4.6V relative to an Li reference electrode. An Li-CI~ secondary battery system was observed to have an open-circuit potential 0f 3.97V, making an Li-C12 secondary battery in molten lithium chlorate possible, in principle. A lithium-lithium chlorate primary battery system is also possible. Lithium negative electrode performance was found to be hindered by corrosion and possiblerunaway reactions with LiC103. Dendrite formation on charging was observed. The solubility of Li20 and LiC1 in LiCIO3 at 145~ is 7.5 • 10 -5 and 1.78 x 10 -3 mol/cm ~, respectively. The diffusion Coefficients are 1.5 • t0 -~ for Li20 and 3.4 • 10 -7 cm2/sec for LiC1. Platinum appeared to be an inert positive electrode for chlorate, chlorine, or oxygen reactions for runs on the order of several hours. Nickel shows an active-passive behavior which is complex. Nickel appears suitable for use in a primary cell for the cathodic discharge of LiC103, but it does not appear suitable for a C12 or O2 electrode.

“…We summarized some thermal decomposition temperatures of lithium salts and lithium salts in polymers based on the relevant references, as shown in Figure 12. [174][175][176][177][178][179][180][181][182] The data indicate that the decomposition temperature of the polymer electrolyte is essentially identical to that of the lithium salt. Moreover, sometimes the interaction of lithium salts and polymers can also contribute to the polymer.…”

Solid‐state Li‐ion batteries have emerged as the most promising next‐generation energy storage systems, offering theoretical advantages such as superior safety and higher energy density. However, polymer‐based solid‐state Li‐ion batteries face challenges across wide temperature ranges. The primary issue lies in the fact that most polymer electrolytes exhibit relatively low ionic conductivity at or below room temperature. This sensitivity to temperature variations poses challenges in operating solid‐state lithium batteries at sub‐zero temperatures. Moreover, elevated working temperatures lead to polymer shrinkage and deformation, ultimately resulting in battery failure. To address this challenge of polymer‐based solid‐state batteries, this review presents an overview of various promising polymer electrolyte systems. The review provides insights into the temperature‐dependent physical and electrochemical properties of polymers, aiming to expand the temperature range of operation. The review also further summarizes modification strategies for polymer electrolytes suited to diverse temperatures. The final section summarizes the performance of various polymer‐based solid‐state batteries at different temperatures. Valuable insights and potential future research directions for designing wide‐temperature polymer electrolytes are presented based on the differences in battery performance. This information is intended to inspire practical applications of wide‐temperature polymer‐based solid‐state batteries.
