 There's urgent need to move away from fossil fuels and use a sustainable energy, such as wind and solar. Sun and wind generates electricity, which cannot be harvested continuously. Therefore, storage of electricity is critical to link energy demands with energy supply. Storing electricity in chemical bonds using batteries and fuel cells offers greater energy stored in smaller space relative to other modes of storage, such as pump hydro. And today, battery technologies are going through a paradigm shift from powering portable electronic devices to powering vehicles and also our grid. Over the last 200 years, batteries have transformed how we live, how we work, and how we interact. The invention of lead acid batteries has powered the first generation of electric vehicles and still used in our conventional vehicles for start-up. The use of nickel cadmium batteries enabled the first use, first generation of portable electronic devices, metal hydride, hybrid vehicles, and today lithium ion batteries have made cell phones and laptop computers ubiquitous in our society. Looking forward over the next 5 or 10 years, lithium ion will continue to grow and dominate the market for electric vehicles because the cost has come down by 10 times over the past decade. For the same reason, it has become the technology for the grid applications. Lithium ion batteries operate by shuttling lithium and electrons back and forth between two host structures, carbon electrodes and also the oxide electrodes. And during this charge, lithium ions have moved from carbon to the oxide electrode to produce work. Today the technology is far from perfect. It can heat up, there's a danger of thermal runaway. During charging of the batteries, oxygen gas can be produced from the oxide electrode and react with a flammable liquid electrolyte to produce heat and cause fire. So we need to improve the safety of the batteries. One solution is to replace the liquid flammable electrolyte with the solid state electrolytes. And lithium ions move as fast in the solids as liquid. Reason discovery of solid state electrolytes have shown they can all perform liquids, enabling the development of solid state lithium batteries. Our research is centered on material discovery and design, where we use experiments and computation to look for transient materials, where we can identify parameters we can use to improve battery performance such as power and energy. For example, we have seen recently that speed of lithium ions in solids can be correlated with the stiffness of materials. And using this correlation, searching for softer materials should give rise to higher lithium ion conduction, which in turn can increase the power of solid state lithium ion batteries. Using in the long term, beyond five years, chemical storage using hydrogen and methane gas can offer greater energy and lower costs and displace lithium ion batteries. They can be produced through electrochemical water splitting or carbon dioxide reduction. The challenge is that the efficiency is low. That means we invest more energy to split the water to produce hydrogen than the energy we get out from using hydrogen to make water. So if we want to reduce energy costs and increase the efficiency, we need to work on new catalysts to promote the reaction rate and increase efficiency of chemical storage. We have shown by controlling the electronic structure of material, say the oxygen P-band center, we can vary the speed of reactions by a million times to make molecular oxygen. And this has to do with reduced barriers for this particular reaction. And we find the best catalyst can exchange molecular oxygen and oxygen with molecular water and through a new reaction pathway. And this catalyst or such a catalyst can increase the efficiency of chemical storage systems using hydrogen or for CO2 reduction or actually for ammonia synthesis. We would like to highlight fundamental electrochemistry research where material design is key in seeding new innovation in storage technologies such as solid state lithium ion batteries, such as chemical storage technologies for powering our vehicles such as hydrogen vehicles or stationary applications. And they can become game changers in the energy space. Thank you.
