Tesla's degradation was greater in the first year of the third year, weaker in the second year, very weak in the third year, and from the fourth year onwards there was almost no degradation. The overall attenuation will not exceed about 15% for iron-lithium batteries, and there will be virtually no attenuation. (No surprise) The standard renewal price is three yuan: EPA range is 380 km. The optimal charge at 80% is 304 km and the ideal charge at 90% is 342 km.
The main differences between ternary lithium batteries and lithium iron phosphate batteries are the following:
Energy density: ternary The energy density of lithium batteries is around 200Wh/kg, while the energy density of lithium iron phosphate batteries is around 110Wh/kg. Therefore, with the same weight, ternary lithium batteries can store more electrical energy.ic, which extends battery life.
Safety performance: Since the cathode material of the ternary lithium battery contains elements such as nickel and cobalt, if overcharged or overdischarged, these elements may cause the release of oxygen and volatilization of the cathode material, causing it to fire or explode. However, the cathode material of lithium iron phosphate batteries does not contain volatile elements, so it has higher thermal stability and overcharge resistance, resulting in higher safety.
Temperature Resistance: Ternary lithium batteries perform best in low temperature environments. For example, at minus 20°C they can release 70.14% of their capacity. In comparison, lithium iron phosphate batteries perform better under the same conditions. terms. Only 54.94% of capacity canbe released. However, in high temperature environments, lithium iron phosphate batteries have a longer service life and their capacity attenuation is relatively low.
