“…Contamination of soil with Li is likely to increase because of its broader occurrence in the environment, particularly with the disposal of Li-ion batteries [15]. Compared to other cations in soil, Li is more mobile and may leach into receiving waters, being taken up by plants, or cause biological damage [16].…”

The extensive use of lithium (Li) ion-based batteries has increased the contamination of soil and water systems due to widespread dispersal of Li products in the environment. In the current study, the influence of Li application on soil fertility and leachate was observed. Three soil samples were collected and five treatments of Li (0, 50, 100, 150 and 200 mg/L) were applied. After three months of Li treatment, leachate was collected and soil samples were subjected to physical and chemical analyses. The results showed that the mean values of soil pH were increased slightly after Li application while electrical conductivity (EC) ranged from 1.2 to 5.1 µS/cm, indicating that soil was slightly saline in nature. The sodium was observed to be greater than the recommended values (0.3–0.7 mg/kg) in Li-amended soil while calcium and magnesium values decreased in soils compared to untreated soil. Mean values of phosphorus and potassium were greater before Li application and reduced considerably after Li application. Leachate analysis showed that all the parameters differed significantly except those of zinc and iron. The EC of leachate samples ranged from 2286–7188 µS/cm, which shows strong salinity. The sodium adsorption ratio (SAR) ranged from 1–11, which indicates that it falls into the marginal soil category. Lithium concentration in leachate samples ranged from 0–95 mg/L, which was significantly higher than the acceptable value for lithium (2.5 mg/L) in leachate. A soil sample (3) with an additional 10% organic matter showed that after Li application, the loss of nutrients in leachate was less as compared to the other two samples, demonstrating that organic matter improved soil conditions and suppressed the negative effects of Li on soil. Our results could raise concerns about risks in situations where food and fodder crops are associated with Li-contaminated waste disposal.

“…Li et al proposed an impedance-based method to describe the heat generation of battery in the process of overcharging, and proposed pulse-relaxation and impedance measurement methods, parameterizing the electro-thermal model on the different state of charge, temperature and charging rate [7]. Zhirong Wang et al researched into the thermal behavior of lithium-ion battery in various thermal environments and rejection of heat, and studied the relationship between failure form and internal reaction of lithium-ion battery through thermal abuse test [8][9][10][11]. Xiaoqing Zhu et al investigated the thermal runaway characteristics of lithium-ion batteries under overcharging conditions and analyzed the temperature changes at different current rates and charging stages [12][13].…”

For the sake of comprehend the influence of locally enhanced heat dissipation of the polar on Li-ion power batteries, coupling the thermal effect of anode and cathode, the heat generation model of Li-ion battery with different discharge magnification is obtained. Based on this model, the discharge process simulation analysis of the single battery is carried out and compared with the experimental results. The experiment results show that battery polarity heat effect has great influence on the temperature field distribution of the battery. Then, a locally enhanced heat dissipation structure is set up near the polar region and a comparative experiment is carried out by changing the discharge rate. Although the heat pipe can only slightly improve the discharge capacity of lithium ion battery by enhancing the heat dissipation capability of polarity, the heat generated under low discharge rate can be reduced by using the heat pipe with low emission rate, the heat generated by the polar region can be effectively and timely exported to reduce the temperature of the polar region and it can greatly reduce the overall temperature of the battery. Then, according to the thermal characteristics and the results of locally enhanced heat dissipation analysis, a new battery module is designed and simulated. And the prototype is completed and tested. The results show that this method can effectively reduce the temperature rise and temperature difference of the battery module by using locally enhanced heat dissipation structure. Finally, combined with the simulation and the experimental results, some useful suggestions are put forward for the design and manufacture of battery modules and battery boxes.

The development of wearable electronics and sensors is constrained by the limited capacity of their batteries. Therefore, energy harvesting from human motion is explored to provide a promising embedded sustainable power supply for wearable devices. Herein, the principles, development, and applications of human motion excited energy harvesters are reviewed. The energy harvesters are classified based on the human motions with distinguished characteristics: center of mass motion (COM), joint motion, foot strike, and limb swing motion. According to the motion characteristics, the principles, features, and limitations of different energy harvesters are discussed, and the power generation performances are compared. Finally, various self-powered applications enabled by embedded energy harvesters are introduced, so as to show the great potential of embedded energy harvesting systems in boosting the development of the wearables.
