Using your laptop while it's running on a battery charge is the main thing to affect your laptop's battery life, both temporarily and potentially permanently, if you do so regularly. Your laptop battery can cope with a certain number of charge cycles before it starts to degrade. CATL said at the event that the Shenxing Superfast Charging Battery is capable of adding 248 miles (400 km) in 10 minutes. The new fast-charging LFP battery is expected to enter mass production in China by the end of the year. The first electric vehicle models equipped with Shenxing batteries will launch in the first quarter of 2024.

The transition to electric vehicles (EVs) is seen as an important means to reduce global carbon emissions from the transport sector, but a number of barriers to mass adoption of EVs have been identified. Technical concerns such as battery range, charging time, and battery life are prominent among these, particularly for battery-only EVs as compared to hybrids (Biresselioglu, Kaplan, and Yilmaz 2018). Increased battery sizes increase the range of EVs and the provision of rapid charging infrastructure reduces charging time, but we ask what effect these have on the third concern of EV battery life? The company has faced challenges of weakening demand and pressure to cut costs from EV makers amid a price war and a slowdown in auto sales this year. CATL has been losing market share to BYD, which powers all its EVs with its own batteries. CATL's biggest client is Tesla.

Cheeseman, H. Fast-charging Li-metal batteries. ARPA-E https://arpa-e.energy.gov/open-2021/webinars (2021). CATL says its new fast-charging battery solves these issues. It’s new LFP battery “embodies the perfect balance of long range and easy refueling.”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.

Commun. 8, 812 (2017). The electricity that comes into our households from the grid is Alternating Current (AC). Most modern electronics, including EVs, use Direct Current (DC) for their operation. During AC charging of EVs, current from the grid is converted into DC using the on-board inverter, whereas in DC charging, the rapid or ultra-rapid charger converts AC into DC.
