Smaller, faster-charging batteries are the answer for affordable and sustainable electric vehicles (EVs) for everyone, everywhere. The ability to quickly refill energy is profoundly important in order to reduce EV cost and demand for critical minerals. In this talk I will present asymmetric temperature modulation (ATM) approach to enabling 10-minute fast charging of energy-dense Li-ion batteries in any temperatures (even at -60°C) while still delivering remarkable cycle life. Recent disastrous events at EV charging stations caused by an arctic blast in Chicago will be given as an example of the dire need for quick energy refill in the extreme cold. Battery fast charging must also work in hot summers along with high-temperature stability of cycling and storage. We shall present novel thermal management concepts for extreme fast charging in both extreme cold and hot conditions. Overall, our development points to a new paradigm of battery design and thermal management without having to trade-off among fast charge, safety, lifetime, and cost.

Electricity is generated at Lamma Power Station located at Po Lo Tsui of Lamma Island. The power station has a total installed capacity of 3,737MW made up of three 250MW coal-fired units, five 350MW coal-fired units, one 55MW gas turbines, four 125MW gas turbines, one 335MW combined cycle unit, one 345MW combined cycle unit, one 800kW wind turbine and one 1MW solar power system. Lamma Power Station provides a safe and reliable supply of electricity for more than 570,000 customers on Hong Kong Island and Lamma Island, and contributes to HK Electric’s world class reliability of more than 99.999%. Following the opening of Hong Kong's first wind power station, Lamma Winds, in 2006, an extension to the power station that burns the more environmentally friendly natural gas became operational the same year. In line with Government policy that aims to increase the use of gas, gas-fired generation has been increased to over 30% of the total output in 2010 when another gas-fired unit was put on use.
