Heating Mechanisms in Gloveboxes with Large Antechambers: A Comprehensive Overview


Gloveboxes with large antechambers are crucial for providing controlled environments in various scientific and industrial applications. These gloveboxes often incorporate heating mechanisms to facilitate specific processes or experiments. In this article, we will delve into the various heating methods used in gloveboxes with large antechambers and explore their benefits and applications.

  1. Overview of Gloveboxes with Large Antechambers: Gloveboxes with large antechambers are specialized enclosures designed to maintain controlled atmospheres while allowing convenient sample transfer or equipment manipulation. The primary chamber provides a controlled environment, typically filled with an inert gas such as nitrogen or argon, while the large antechamber serves as a spacious interface between the internal and external environments.

  2. Importance of Heating in Gloveboxes with Large Antechambers: Heating mechanisms play a pivotal role in gloveboxes with large antechambers by enabling temperature control for various purposes. These may include sample preparation, material synthesis, drying processes, or experiments requiring specific temperature ranges. By offering precise and uniform heating capabilities, gloveboxes with large antechambers enhance experimental control and yield reliable results.

  3. Common Heating Methods: a. Electric Resistance Heating: Electric resistance heating is one of the most common methods used in gloveboxes with large antechambers. This mechanism involves the use of electric heating elements positioned strategically within the system. These elements generate heat when an electric current passes through them. The generated heat is then transferred to the antechamber via radiation and convection, subsequently increasing the temperature within the desired range.

b. Infrared (IR) Heating: Infrared heating is another popular method employed in gloveboxes with large antechambers. Infrared heaters emit electromagnetic radiation in the infrared spectrum, which directly heats the targeted objects or surfaces without significantly affecting the surrounding environment. This mechanism allows for quick and efficient heating, making it suitable for processes requiring rapid temperature changes or localized heating.

c. Induction Heating: Induction heating relies on electromagnetic induction to generate heat within conducting materials. In gloveboxes with large antechambers, induction heating is achieved by placing a high-frequency alternating current (AC) coil near the target material. The AC current induces eddy currents within the material, resulting in resistive heating. Induction heating offers precise temperature control and is frequently used for applications involving metallic samples or materials.

d. Convection Heating: Convection heating involves transferring heat through air or an inert gas circulating within the glovebox system. This technique utilizes heating elements or coils to warm up the gas or air, which is then circulated through the main chamber and the large antechamber. As the heated gas or air comes into contact with the samples or equipment, heat transfer occurs, raising the overall temperature. Convection heating provides uniform temperature distribution, making it suitable for heat-sensitive materials or processes that require even heating.

  1. Temperature Control and Regulation: Gloveboxes with large antechambers incorporate sophisticated temperature control systems to maintain precise and stable temperatures. These systems typically consist of temperature sensors strategically placed within the system, feedback mechanisms, and controllers. The controllers receive signals from the sensors and automatically adjust the heating mechanism accordingly to achieve and maintain the desired temperature range.

  2. Benefits and Applications: The utilization of heating mechanisms in gloveboxes with large antechambers offers several benefits and widens the range of applications. Some notable advantages include:

a. Enhanced Material Synthesis: Controlled heating plays a critical role in material synthesis processes within gloveboxes. By precisely controlling the temperature, researchers can influence reaction rates, crystal growth, and phase transitions, enabling the synthesis of high-quality materials with tailored properties.

b. Drying Processes: Heating mechanisms expedite the drying of samples or components within gloveboxes. By maintaining elevated temperatures, moisture evaporates more rapidly, reducing drying time and enhancing productivity.

c. Thermal Testing: Gloveboxes with large antechambers equipped with heating mechanisms are ideal for conducting thermal testing on various materials, such as polymers, composites, or electronic components. The controlled heating allows researchers to simulate real-world conditions and evaluate the behavior of materials under different temperature regimes.

d. Sample Preparation: Certain experiments or processes may require temperature-controlled sample preparation. Heating mechanisms enable researchers to preheat samples to specific temperatures before introducing them into the main chamber, ensuring consistent initial conditions for subsequent experiments.

e. Environmental Simulations: Heating mechanisms allow gloveboxes with large antechambers to simulate specific environmental conditions, such as elevated temperatures, that are crucial for testing and evaluating samples or equipment intended for use in extreme environments.

Glove box for lithium batteries: "Umbrella" for battery production and recycling

I. Lithium power battery recycling

Lithium power battery recycling refers to the rational use of used lithium power batteries for new energy vehicles at multiple levels. Power battery capacity will continue to decrease with the increase in the number of times of use, power attenuation to 80% after the inability to meet the new energy vehicles to provide power, and had to face the elimination, it can only enter the recycling stage. The utilization rate of retired lithium-ion power batteries for electric vehicles has reached 60%. Therefore, how to play out the residual value of retired power batteries has become the focus of attention, this behavior is also regarded by enterprises as an effective measure to reduce costs and increase efficiency, and even become the emerging business of some companies to increase revenue.


In recent years, with the rapid development of the new energy automobile industry, the production of lithium batteries as power batteries has also shown a spurt of growth. The life span of lithium batteries is about 5 to 7 years, which also breeds a huge lithium battery recycling market. The market size created by recycling metals such as cobalt, nickel, manganese, lithium, iron and aluminum from used lithium batteries in China is expected to exceed 10 billion yuan in 2020, and up to 25 billion yuan in 2023.

From the market, the widely used lithium batteries, mainly lithium-ion batteries, can be divided into lithium manganese-acid batteries, lithium cobalt-acid batteries, lithium iron phosphate batteries, and ternary lithium batteries according to the different cathode materials.


For different types of lithium batteries, the recycling method used is different, such as lithium iron phosphate batteries contain only lithium metal, although the direct recovery of lithium value is not high, but its cycling performance and stability is better, you can first use the gradient utilization of the full use of the way to make full use of the end-of-life recycling; and ternary lithium batteries contain nickel, cobalt, manganese and other high-value metals, but poorer cycling and safety, is not applicable to gradient utilization, but can be directly used for gradient utilization, and can be directly used in the recycling of lithium batteries. It is not suitable for gradient utilization, but can be directly scrapped for resource transformation.


Ⅱ、Domestic and foreign recycling market: late start but in growth


Lithium-ion batteries were born in the 1970s, and only began to be commercialized in the 1990s. As the early lithium batteries are mainly used in the form of buttons and other small batteries and the use of less, the recovery value is low, the recovery method is similar to other batteries, physical disassembly after the use of acid and other extracts. Therefore, at this stage, the patent application on lithium battery recycling is relatively small, the global annual patent applications in about 20 pieces, mainly using wet metallurgy to extract high-value metals.


After 2009, with the large number of electric vehicles and electronic products, the use of lithium batteries showed a sharp increase in the trend, and lithium battery recycling-related annual patent applications have increased to nearly 100, including China, the world's major lithium battery market, a number of companies have been involved in the study of lithium battery recycling, the relevant patent applications related to the pre-treatment of waste lithium batteries, cathode material separation, valuable metals, extraction, electrolyte treatment, etc., and the use of lithium battery recycling. Extraction, electrolyte treatment and other aspects of lithium battery recycling.


The battery recycling technologies of different enterprises are different. For example, Sumitomo Metal, as a supplier of cathode materials for Tesla and Toyota car batteries, mainly used high-temperature roasting combined with crushing, screening and other dry metallurgy to recover nickel and cobalt from lithium battery electrodes in the early days. However, due to the high energy consumption of this treatment and not easy to recover lithium, aluminum and other metals, so Sumitomo Metal began to use wet processing to recover lithium, and research on the extraction agent. Another Japanese company, Nippon Mining & Metals, mainly conducts research on hydrometallurgy, and adopts solvent extraction to efficiently separate and recycle nickel, cobalt, manganese, copper, iron, aluminum, and lithium in lithium battery wastes, etc. After 2013, the relevant research of foreign companies tends to improve the environmental friendliness and economy in the process of recycling batteries, such as the use of low-toxicity or even non-toxicity solvents, simplifying the recycling process, and treatment of fluorine electrolyte, and the recycling technology has not appeared. There is no obvious breakthrough in recycling technology.


Domestic patent applications on lithium-ion battery recycling began to be submitted from 2001, the overall trend of increase year by year, of which between 2001 and 2008, the total number of related patent applications in China is relatively small, after 2009, the increase in the number of related patent applications is larger, from the original annual patent applications more than 40 pieces of rapid growth to more than 400 pieces, and is still in a fast-growing stage. Overall, both from the industrial growth, or from the lithium battery recycling technology progress, the global lithium battery recycling is still in the primary stage, and with the increase in waste lithium batteries and related policies to promote the lithium battery recycling in the next few years will inevitably see rapid development.


Ⅲ、Technology


In the recycling and production process of lithium batteries: the high chemical activity of lithium metal anode is prone to side reactions with the electrolyte. Fuel cell production awards face more unknown factors: it can be said that the entire battery production process is accompanied by many dangerous problems, so in the battery production, are used in the vacuum

Method for Improving Film Thickness Uniformity of Magnetron Sputtering

Among various sputtering coating technologies, magnetron sputtering technology is one of the most important technologies. In order to prepare large-area and uniform thin films with consistent batches, the target base distance is optimized, the substrate movement mode is changed, and the film thickness is implemented. Monitoring and other measures. Multi-station magnetron sputtering coating equipment has been paid more and more attention and used because of its adjustable speed ratio and simultaneous production of multiple substrates, which greatly improves the efficiency.

In the actual coating, sometimes the target material is not suitable for opening holes in the middle, and for the stone-controlled sputtering system, the method of improving the uniformity of the film thickness by changing the target shape in actual production is not feasible. Therefore, it is very necessary and important to find a feasible method that can improve the uniformity of the film thickness.

Provide a multi-functional magnetron sputtering coating system, which is integrated by a vacuum coating system and a glove box system, which can complete thin film evaporation in a high vacuum evaporation chamber, and under a high purity inert gas atmosphere in the glove box. Carry out the storage and preparation of samples and the detection of samples after evaporation. The combination of evaporation coating and glove box realizes the fully enclosed production of evaporation, packaging, testing and other processes, so that the entire film growth and device preparation process is highly integrated in a complete controllable environment atmosphere system, eliminating the organic large-area circuit preparation process. The influence of unstable factors in the atmospheric environment guarantees the preparation of high-performance, large-area organic optoelectronic devices and circuits.
