The new coating can make the lightweight metal lithium battery safe and long lasting

A new coating can make lightweight lithium metal batteries safe and durable. Core Tip: The new coating uniformly transports charged lithium ions to the electrode by forming a molecular network, thereby preventing the formation of lithium. It can prevent unnecessary chemical reactions in the battery, and can also reduce the accumulation of chemical substances in the anode, thereby preventing them from destroying the battery's power supply. According to a study published in the 'Joule' magazine, researchers at Stanford University and the SLAC National Accelerator Laboratory in the United States have invented a new coating that can make lightweight metal lithium batteries safe and durable, leading to the emergence of the next generation of electric vehicles . In laboratory tests, the coating significantly prolonged the life of the battery and dealt with the burning problem by greatly restricting lithium from passing through the barrier between the positive and negative electrodes of the battery. The researchers pointed out that lithium metal batteries have at least one-third more energy per pound than lithium batteries and are very light because they use lightweight lithium as a positive charge instead of heavier graphite. From laptops to mobile phones, portable electronics may benefit from more reliable lithium metal batteries, but the real source of income will be cars. The biggest resistance of electric vehicles is that the battery itself accounts for a quarter of the cost, and this is the core of the problem. The capacity of traditional lithium batteries has reached the limit, so it is crucial to develop new batteries to meet the high energy density requirements of modern electronic devices. Research teams from Stanford University and Stanford University tested their coating on the positive electrode (called the anode) of a standard lithium metal battery. In the end, they combined this specially coated anode with other components on the market to create a fully functional battery. After 160 cycles, their lithium metal battery still supplies 85% of the energy of the first cycle. Ordinary lithium metal batteries can only release about 30% of their energy after multiple cycles. Even if they do not explode, they are of little use. The new coating prevents the formation of lithium by forming a molecular network that uniformly transports the charged lithium ions to the electrode. It can prevent unnecessary chemical reactions in the battery, and can also reduce the accumulation of chemical substances in the anode, thereby preventing them from destroying the battery's power supply.
