What are your thoughts on charging best practices ?
They say NMC battery is best to keep between 20%-80% range, and it is better to charge from 20%. Some say LFP can go up to 100% , yet others believe it is still battery hence better to use 80% max rule of thumb. For your friend that does intermittent charging, is it bad for the battery ? I have read claims that it is best to start charging from 20%.
I learned from a video Tesla has all the charging data from their customers for more than a decade. The conclusion was fast charging or slow charging makes no difference to the battery life, at least up to 10 years. Yet people are saying fast charging is bad for battery. On the other hand, BYD is talking about megawatt charging. If fast charging is bad, what is BYD talking about ?
Gemini copy and paste answer for LFP, its cathode construction allowed more beating to enable longer charge cycles life.
LFP batteries feature a cathode made of lithium iron phosphate (LiFePO4) and an anode typically made of graphite, offering advantages like long cycle life, safety, and thermal stability, while having a lower energy density compared to other lithium-ion chemistries.
Here's a more detailed breakdown:
Cathode (Positive Electrode):
Material: Lithium iron phosphate (LiFePO4).
Key Features:
Safety: LiFePO4 is known for its high thermal and chemical stability, making it a safer cathode material compared to some other lithium-ion chemistries.
Long Cycle Life: LFP batteries exhibit a long cycle life, typically exceeding 2,000 cycles, meaning they can be charged and discharged many times before significant degradation.
Abundant Raw Materials: The iron and phosphate components of LiFePO4 are readily available and environmentally friendly.
Cobalt-Free: LFP batteries do not contain cobalt, a material often associated with environmental and ethical concerns.
Good Performance in Extreme Temperatures: LFP batteries perform well in a wide range of temperatures, including high and low temperatures.
Anode (Negative Electrode):
Material: Typically graphite or other carbon-based materials.
Key Features:
Lithium Ion Storage: During charging, lithium ions are extracted from the cathode and intercalated into the anode material.
Reversal during Discharge: During discharge, the process is reversed, with lithium ions moving back from the anode to the cathode.
Charging Speed: Anode materials play a crucial role in determining the charging speed of the battery.
In Summary:
LFP batteries use LiFePO4 as the cathode material, known for safety, long life, and environmental friendliness.
The anode is typically made of graphite, facilitating the storage and movement of lithium ions during charging and discharging.
the seal is one I didn’t test drive as I didn’t like the seat. Too hard for me and passenger.
