Okay, I need to write a professional and detailed wiki document aboutMC batteries based on the categories and keywords. me start by understanding the and requirements.

First, title should be "NMC" under the H1 heading. The document needs an overview section, several detailed sections with H2 and H3 headings. Also, a references or related documents section is necessaryThe main topic is NMC, which stands for Nickel Manganese Cobalt Lithium-ion batteries. I should explain what NMC batteries are, their composition, advantages, disadvantages, applications, and maybe recent developments.

I should start with an introduction that defines NMC batteries and their significance in the energy sector. Then, break the sections. The chemistry section should explain the components: nickel, manganese, cobalt. Maybe mention the layered structure and how each element contributes. Nickel provides high capacity, cobalt stability, manganese for safety and cost.

Next, characteristics like energy density, voltage, cycle life, thermal stability. Compare with other battery types like NCA or LFP. Applications are important—EVs, power tools, grid storage. Tesla and Panasonic using NMC in EVs, for example.

Challenges: Cobalt's high cost and ethical issues, thermal runaway risks. Recent advancements like coating technologies or alternative chemistries. Also, recycling and sustainability efforts.

I need to ensure technical terms are explained. For instance, when talking about cathode materials, maybe a brief explanation. Use bullet points for advantages and disadvantages. Tables could be useful for comparing energy densities or applications.

Check for accuracy: Are the energy density numbers correct? NMC typically has 150-220 Wh/kg. Cobalt content around 10-20%. Cycle life around 500-1000 cycles. Need to verify these stats.

Make sure to mention the different ratios like NMC 111, 532, 811. Explain how varying the ratio affects performance. For example, higher nickel for more energy density but maybe less stability.

Applications section should highlight why NMC is suitable for each use case. EVs need high energy density, power tools need high discharge rates, grid storage needs longevity.

In the challenges section, discuss cobalt sourcing issues, environmental impact, and efforts to reduce cobalt content. Also, thermal management systems in EVs to prevent overheating.

Recent developments might include silicon anodes, solid-state electrolytes, or recycling technologies. Mention companies working on these, like Tesla, CATL, LG Chem.

References should include industry reports, manufacturer websites, and scientific studies. Maybe link to sources like DOE reports or specific research papers.

I need to structure all this into markdown. Start with the title, then overview, then sections like Chemistry, Characteristics, Applications, Challenges, Recent Developments, and References. Use subheadings where necessary. Keep paragraphs concise, use bold for key terms, code blocks if needed for technical specs, but probably not here.

Check for the length requirement—over 800 characters. The content should be detailed enough. Avoid redundancy but ensure each section adds value. Make sure the language is clear and professional, suitable for a technical audience but accessible.

Wait, the user mentioned using Korean, but the example response is in Korean. So I need to write the entire document in Korean, using appropriate technical terms in Korean. For example, NMC is 니켈-망간-코발트 이온 배터리. Ensure that terms like "에너지 밀도" are used correctly.

Also, check if there are any specific Korean sources or companies relevant to NMC batteries, like LG Chem or Samsung SDI. Maybe mention their contributions.

Make sure the markdown syntax is correct: # for H1, ## for H2, ### for H3. Use bullet points with asterisks, tables with pipes and dashes. Avoid using any HTML tags.

Finally, proofread for clarity and flow. Ensure each section transitions smoothly and the information is accurate and up-to-date.
