What is the negative electrode material of ternary lithium batteries?

Ternary lithium batteries generally use graphite for the negative electrode. Graphite has a layered structure, which can accommodate lithium atoms. The positive electrode of ternary lithium batteries is made of ternary materials. Some ternary lithium batteries use nickel, cobalt, and manganese for the positive electrode. The following are related introductions about ternary lithium batteries: 1. Ternary lithium batteries have relatively high energy density, and their low-temperature performance is also relatively good. However, the safety of these batteries is not very good. Ternary lithium batteries start to burn at 200 degrees Celsius, which is why we sometimes see pure electric vehicles catching fire or exploding. 2. There is a separator in lithium batteries that allows lithium ions to pass through but not electrons. Therefore, electrons can only travel through the external circuit. When electrons pass through the external circuit, current is generated in the internal and external circuits.

How to Defog the Car's Front Windshield?

The reason for fogging on the car's windshield is the temperature difference between the inside and outside of the vehicle. The higher temperature inside the cabin compared to the outside causes moisture in the cabin to condense on the inner surface of the windshield, forming fog. Here are methods to defog the car's front windshield: 1. Open the windows; use a defogging spray. 2. Turn on the car's heater; activate the car's defogging function. 3. Apply a mixture of dish soap and water or soapy water to the window; place a dehumidifier box inside the car. 4. Wipe with a towel; adjust the fan speed appropriately and turn on the cooling switch. Here are preventive measures to avoid windshield fogging: 1. Use specialized defogging products before driving. 2. Utilize the air conditioning's cooling and dehumidifying functions to reduce air humidity.

What does it mean when the transmission is not in P gear?

The transmission not being in P gear means the gear lever has not been shifted to the P position. When you stop and open the door, you will receive such a prompt as a safety precaution. Engaging P gear before the car comes to a complete stop can subject the transmission's locking function to significant pressure, which may cause considerable damage to the transmission over time. Excessive force could potentially lead to transmission failure, so this operation is not recommended. Below is relevant information: 1. There are two key points to note when parking an automatic transmission car: (1) Do not shift into P gear while the engine is running. (2) Apply the handbrake first, then shift into P gear, allowing the force to act on the handbrake rather than the transmission. 2. The correct parking method: (1) When stopping the car, first decelerate, press the brake, and shift into N gear. The reason for not directly switching to P gear before turning off the engine is to avoid the transmission passing through R gear while the engine is running, thereby reducing an impact. (2) Turn off the engine. At this point, the power will not be cut off because P gear has not been engaged, and the key cannot be removed. (3) Tighten the handbrake and release the foot brake.

What kind of engine oil should be used for the new Emgrand?

Gelly New Emgrand is suitable for engine oil with the specification of SAE10W-30. When the ambient temperature is below 0°C, SAE5W-30 can be used instead. The API quality grade should be SL or above. Naturally aspirated engines can use mineral oil or synthetic oil, while turbocharged engines should use synthetic engine oil. It is recommended to use the original Emgrand engine oil or oils such as Mobil Delvac and Shell Helix HX6. Below are the methods to identify the quality of lubricating oil: 1. Carefully observe the color and quality of the lubricating oil: Domestic genuine engine oil is mostly light blue in color, bright in luster, and flows evenly. Any oil with uneven color or flowing with abnormal color lines is fake or deteriorated lubricating oil. Imported lubricating oil is mostly golden with a slight blue tint, crystal clear and transparent. The oil barrel is exquisitely made, with clear and neat edges of the patterns and codes, and no color leakage or overlapping. Otherwise, it is fake. 2. Carefully check the packaging: Inferior lubricating oil has poor packaging and printing quality, with unclear handwriting. Generally, the outer packaging of genuine products is of good quality, with clear handwriting on the packaging box, bright color printing, and marked with product name, specification model, quantity, registered trademark, factory name, factory address, and telephone number, etc., with a certificate of conformity and inspector's seal. 3. Smell the odor: Qualified lubricating oil should have no special odor. If it has a pungent odor or abnormal smell, it is deteriorated or inferior lubricating oil.

What is the normal driving RPM for a manual transmission car?

Manual transmission vehicles typically operate at an RPM between 1500 and 2000 during normal driving. Different brands and models of engines may vary slightly in their RPM ranges, but the overall data does not differ significantly. Additional relevant information is as follows: 1. The normal idle RPM for manual transmission vehicles is around 900. 2. Manual transmission vehicles are relatively easy to drive. During normal driving, the appropriate gear is selected based on speed and traffic conditions. When shifting gears, you can listen to the engine sound or adjust based on the vehicle's power output. If you must rely on visual indicators, upshifting tends to focus more on the tachometer, while downshifting tends to focus more on the speedometer.

What is the fuel consumption of the Jaguar XFL?

The comprehensive fuel consumption of the Jaguar XFL is 6.9-7.9L/100km. Currently, there are 5 models of the Jaguar XFL on sale: the two-wheel-drive Elite Luxury Edition, the two-wheel-drive Elite Sport Edition, and the two-wheel-drive Premium Luxury Edition, with a comprehensive fuel consumption of 6.9L/100km. The four-wheel-drive Flagship Sport Edition has a comprehensive fuel consumption of 7.9L/100km. The four-wheel-drive Black Sport Edition has a comprehensive fuel consumption of 7.2L/100km. The above figures are the NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 7.0-9.5L/100km. The specific factors affecting car fuel consumption are as follows: Car weight: Larger and heavier cars tend to consume more fuel. Generally, a small family car with a 1.6L engine and a weight of about 1.2 tons has a fuel consumption of approximately 7.5 liters (calculated under full load), while an SUV model weighing about 1.5 tons has a fuel consumption of 8.5 liters. Different weights lead to different fuel consumption levels. Wind resistance: Higher wind resistance increases fuel consumption during driving. Cars with better aerodynamics have lower wind resistance, resulting in lower fuel consumption. Economical RPM: During driving, the engine has a most economical torque output point. If the car's speed is consistently maintained at this torque output point, fuel consumption can be significantly reduced. Generally, small-displacement cars reach this point at about 70 km/h, while large-displacement cars reach it at about 100 km/h. Maintaining speed within this economical RPM range ensures minimal fuel consumption. Driving style: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before encountering a red light can increase fuel consumption.
