DOE stands for Design of Experiments, a statistical method for planning, conducting, and analyzing controlled tests.

• DOE helps identify relationships between factors and responses in experiments.

• It allows for efficient experimentation by varying multiple factors simultaneously.

• Example: In a manufacturing process, DOE can optimize temperature and pressure to improve product quality.

• It is widely used in quality contr...read more

A lithium battery consists of three main components: anode, cathode, and electrolyte, crucial for its operation and efficiency.

• Anode: Typically made of graphite, the anode stores lithium ions during charging and releases them during discharging.

• Cathode: Commonly composed of lithium metal oxides (like LiCoO2), the cathode is where lithium ions are stored and released.

• Electrolyte: A lithium salt dissolved in a solve...read more

Lithium batteries face issues like thermal runaway, limited lifespan, and environmental concerns, impacting safety and sustainability.

• Thermal Runaway: Lithium batteries can overheat and catch fire if damaged or improperly charged, as seen in incidents with certain smartphone models.

• Limited Lifespan: They typically last 2-3 years or 500-1500 charge cycles, leading to waste and the need for replacements in devices l...read more

To prolong lithium-ion battery life, manage charge cycles, temperature, and storage conditions effectively.

• Avoid Deep Discharges: Regularly charge the battery before it drops below 20% to prevent deep discharge, which can shorten lifespan.

• Optimal Charging: Use a charger that matches the battery specifications and avoid overcharging, as this can lead to overheating.

• Temperature Control: Keep batteries in a cool, dry...read more

Negotiation is a strategic discussion aimed at reaching an agreement, crucial for effective purchasing.

• Negotiation involves communication between parties to reach a mutually beneficial agreement.

• It is important for securing favorable terms, such as price, quality, and delivery schedules.

• Example: A purchase executive negotiating bulk discounts with a supplier can significantly reduce costs.

• Effective negotiation bui...read more

Maintaining FIFO (First In, First Out) ensures that oldest stock is used first to prevent expiry or obsolescence.

• Label shelves with dates to easily identify oldest stock

• Regularly rotate stock to bring older items to the front

• Train staff on FIFO principles to ensure compliance
