Analyze some new applications of lithium battery technology in the future

The future development prospects of lithium batteries are very broad, and the technological innovation of lithium batteries in the future will continue to change our lives. Below the application of science fiction, I will analyze some new applications of lithium battery technology in the future, which may enter our lives on a large scale in the future. Piezoelectric materials Piezoelectric materials exhibit electrical charges when subjected to mechanical stress. Basically, if you squeeze, squeeze or squeeze it, mechanical energy is converted into electrical energy. Step by step, scientists have developed a small coin-sized lithium battery device, which can be embedded in the sole of the shoe. Every time the foot is on the ground, it will cause a small force on the device. Therefore, the piezoelectric film in the middle is compressed, and it generates An electric charge causes lithium ions from the cathode to the anode, like the charging process of inserting a standard lithium battery charging power source outside. The key to this technology is the development of piezoelectric charging devices, which will not supply enough energy to run your phone, but may be enough for GPS tracking devices. 2. Sound-driven zinc oxide is a piezoelectric material. When its tiny nanorods are exposed to sound waves, they will bend, physical stress and electric current will appear. The nanorods are placed on electrical contacts between the metal plates and connected to a tiny lithium battery. The lithium battery absorbs the current from the bent nanorods. This technology is the first to make a sound battery, and when it is exposed to daily noise, voltages of up to 5 volts can appear. 3. The durable battery is small in size, light in weight, and very flexible. It draws energy from the mechanical energy of the person carrying it. A generator placed in a backpack or clothes can convert the mechanical energy felt when walking or running into electrical energy. This electrical energy is then used to charge flexible, fabric-based lithium batteries. The use of conductive fabrics to establish connections between all the different components allows for the design of flexible new wearable technologies. Renewable energy The complete storage of renewable energy such as solar and wind energy is regarded as the power of the future, and it is a good choice to combine it with lithium-ion technology. As large lithium batteries become cheaper, they can be used as household batteries in the future. Solar panels are installed on the roof to continuously store solar energy during the day. Advanced Lithium Technology Next, I will analyze several new technologies for lithium batteries, which will bring future technological innovations. 1. Graphene covered silicon anode technology When silicon is used as the anode material, its energy storage capacity has been greatly improved. Compared with traditional graphite electrodes, the theoretical capacity of silicon has increased tenfold. However, the inclusion of lithium ions in its lattice structure has significantly increased its volume by more than 300%. When the battery is discharged, lithium ions are released from the silicon anode and the silicon shrinks. Over time, this repeated expansion and contraction caused the silicon anode to rupture and rupture, resulting in a very short battery life. The solution is to cover the silicon with graphene, because graphene sheets can slide against each other to compensate for the expansion and contraction of silicon, which is almost twice the energy density of the battery. 2. Graphite anode Graphene can also replace graphite as the negative electrode of lithium batteries. Graphene is made up of sheets of carbon atoms connected together to form a sheet with the thickness of one atom. Lithium ions are quickly inserted into graphite, which is the key to high-power or fast charging applications, and may also cause anode breakdown. Graphene sheets can be used for high-power applications, and lithium ions do not need to pass through the graphite crystal tunnel to reach the insertion position. Around the world, many scientists are studying this new material, trying to develop it into a new battery electrode material. 3. Lithium-air lithium-air batteries can use oxygen in the surrounding atmosphere as a cathode material to extract energy from thin air, which will make them very light and make their energy density 10 times higher than standard lithium batteries that compete with gasoline . However, lithium-air batteries also have some challenges. In pure metal form, lithium is highly reactive, making it difficult to maintain the stability of lithium anodes. Finding an electrolyte that keeps the anode stable and prevents it from reacting with oxygen in the air is a challenge.
