Advanced Lithium-Ion Batteries
Existing lithium-ion batteries are extremely flammable, sensitive to high temperatures, need overcharge or complete discharge protection, and become weak with age. In addition, there is also a significant environmental impact associated with mining materials for battery production. The advancement of Li-ion battery technology is a noticeable trend in the energy storage field. Therefore, startups are modifying lithium-ion batteries to increase their performance and lifetime. To achieve this, lighter and energy-dense materials such as li-polymer, li-air, li-titanate, and li-sulphur replace the traditional lithium-cobalt electrodes.
Furthermore, some startups recycle used batteries, advancing the circular economy. Recycling Li-ion is a novel trend to solve the battery waste issue. Releasing hazardous chemicals, including acids and heavy metals like mercury and lead, harms the environment. A few players alter the constituents to reduce the environmental impact. Such startups have observed results in purity enhancement while reducing the production time of the rejuvenated cathode. Solving the charging time of Li-ion batteries is another trend in the new and renewable energy sectors.
Lithium Alternatives
Another new trend in energy storage is finding alternatives to lithium-ion batteries. Lithium batteries are not environmentally friendly, and keeping up with the increasing demand for lithium is difficult. For example, zinc-air batteries are a viable alternative to lithium because of zinc’s abundant supply, inherent stability, and low toxicity. Sodium-sulphur batteries are also efficient alternatives. These batteries feature longer lifespans, a greater charge or discharge cycle, high energy density, and are fabricated of relatively inexpensive materials. Other promising battery chemistries are aluminium ion, magnesium ion, nickel-zinc, and silicon-based batteries.
Sodium-ion battery technology is a robust alternative to its lithium counterpart. Recently, researchers have developed a material for sodium-ion batteries: a powder of sodium-vanadium phosphate fluoride with a particular crystal structure. It is used in the battery cathode to gain record-high energy storage capacity, avoiding some of the congestion of the emerging sodium-ion technology. These technological improvements, innovations, and developments are leading to a massive shift from traditional to renewable energy sources.
