CATLs new fast-charging LFP battery is equipped with in-house technology, including fast ion ring technology, a new superconducting electrolyte formulation, and an ultra thin and safer separator. We define battery life and the processes causing battery degradation, then review the sparse literature empirically testing battery degradation. As degradation and the impact of charging speeds are dependent on the size and type of battery, we use web searches to synthesize information on how choosing different charging options affect battery life for common EV models in the UK.

Power Sources 446, 227366 (2020).Like propellers, LiPo batteries are a consumable in the hobby, however they should last longer than your props, as long as you treat them well! I mentioned internal resistance earlier, this is what kills your batteries over time. The more you use a LiPo, the more the internal resistance increases. Internal resistance can be thought of as a component within your battery that uses electrical energy, leaving less power for your motors.

There is a phenomenon known as ‘Voltage Sag’– The higher your throttle input, the faster you deplete your battery, but this depletion is not linear. At very high throttle the voltage drops even faster, but as you decrease throttle, the voltage will recover, the lower the C rating of your battery the more pronounced the voltage sag will be, and the longer it will take for the voltage to increase again. Note – Batteries with a higher C rating will usually be slightly heavier, than others with the same voltage and capacity. Zhang, J., Wu, B., Li, Z. & Huang, J. Simultaneous estimation of thermal parameters for large-format laminated lithium-ion batteries. J. Power Sources 259, 106–116 (2014). The new LFP battery will enable up to 434 miles (700 km) range. CATL claims its new innovation is the world’s first LFP battery to support 4C charging, as well as a “battery for everyone.” For those that don’t know, the “C” refers to the charging multiplier of the battery. Hence 4C can charge in a quarter of an hour. Li, Y. et al. Growth of conformal graphene cages on micrometre-sized silicon particles as stable battery anodes. Nat. Energy 1, 15029 (2016).Lee, S.

Mass production is expected by the end of the year with new EVs equipped with the fast-charging battery avaialable on the market in the first quarter of 2024.
