Lithium-ion batteries have revolutionized renewable energy storage technology, not only for portable phones but also for storage in electric grid and the automotive sector. Consumer expectations on lithium-ion batteries have become more demanding. Batteries need to charge faster, weigh less, be smaller, store for longer yet perform better and safer. Battery manufacturers and researchers alike need to rely on multiple techniques to design and perform quality checks on such high performing batteries. In this free online workshop, Malvern Panalytical partners with NDC and our distributor in Taiwan, DKSH, to share with you on the cutting-edge technologies for battery cathode, anode, coatings and other raw materials.


Structural performance analysis using X-ray diffraction
利用 XRD 進行結晶結構特性分析

The important critical parameters which influence the battery performance are primary particle size, crystalline phases, composition, and coating thickness of the electrode materials. These parameters can be extracted from the data collected using X-ray diffractometry.

Crystalline phase composition defines the overall electrode material quality and its suitability for the battery cell manufacturing. X-ray diffraction is the technique of choice when it comes to the analysis of crystalline phases. Malvern Panalytical's X-ray diffractometer range which includes the Aeris compact XRD is an easy to use instrument with superb data quality. Battery researchers and QC managers use the Aeris for accurate analysis of:

• Crystalline phase composition and presence of any residual reactants (optimization of calcination process)

• Crystallite size (related to the primary particle size)

• Degree of graphitization in synthetic anode graphite

The X-ray diffraction (XRD) technique is a non-destructive technique and heavily used in laboratory work for various applications such as identification and quantification of crystalline phases and average crystallite size analysis of synthesized powder materials. The extracted crystallographic information such as interlayer spacing can be used to calculate the degree of graphitization or the orientation index in graphite battery anode materials. Also important to know phase of cathode

結晶相組成是電極材料極為重要的一個因素,大大影響了電池的品質。而XRD) 技術正是相分析的唯一選擇。簡易操作的桌上型Aeris XRD有著出眾的品質,可以針對以下需求進行分析

• 結晶相組成和任何殘留反應物的存在(煅燒過程的優化)

• 微晶尺寸(與初級粒徑相關)

• 合成陽極石墨的石墨化程度

XRD) 技術是一種非破壞性技術,在實驗室工作中大量用於各種應用,例如結晶相的識別和量化以及合成粉末材料的平均微晶尺寸分析。提取的層間距等晶體學訊息可用於計算石墨化電池負極材料的石墨化程度或取向指數。亦可分析正極材料的相分析。

Elemental analysis for energy density and charge cycles

The ratio between nickel, manganese, and cobalt in a battery’s cathode determines its energy density (and the lifetime of one charge cycle) as well as the number of charge cycles it can withstand. That’s where X-ray fluorescence (XRF) comes in. Although traditionally overlooked, it provides significant benefits to battery manufacturing. Specifically, our new benchtop XRF, Epsilon 4, can determine elemental composition in just 10 minutes during production.

電池陰極中鎳、錳和鈷的比例決定了它的能量密度(和一個充電週期的壽命)以及它可以承受的充電週期數。這就是 X 射線熒光 (XRF) 的在電池分析的重要性。 儘管傳統上被忽視,但它為電池製造提供了顯著的好處。具體來說,它可以在生產過程中在短短 10 分鐘內確定元素組成。

Particle size and shape analysis for improved battery packing density, uniformity of coatings and more

Electrode material and battery slurry particle size and shape variations must be regularly measured and optimized throughout the production process to maintain consistent battery performance. Based on laser diffraction, our Mastersizer 3000 offers the easiest, most accurate way of measuring cathode and anode material particle sizes. And, for industrial process environments, it can be replaced by our Insitec on-line particle size analyzer to provide real-time data for process control. Our Morphologi 4 optical imaging tool can analyze the size and shape of statistically relevant ensembles of particles in just a few minutes.

利用MS3000雷射粒徑分析儀來管控電池材料及漿料的顆粒尺寸及形狀是最簡單且精確的品管工具。就大量生產的客戶我們還提供了另一種線上即時監控的解決方案Insitec on-line particle size analyzer。還有 Morphologi 4是一種光學影像的工具,可以在幾分鐘內分析出顆粒尺寸及形狀。
