Top 10 Energy Storage Trends in 2022

1. Advanced Lithium-Ion Batteries

Lithium-ion batteries offer advantages such as portability, fast recharging, low maintenance, and versatility. However, they are extremely flammable, sensitive to high temperatures, require overcharge or complete discharge protection, and suffer from aging. Moreover, there is a huge environmental implication to mining the components for battery manufacturing. Therefore, startups are modifying lithium-ion batteries to increase their performance and lifetime. To achieve this, lighter and energy-dense materials like li-polymer, li-air, li-titanate, and li-sulfur replace the traditional lithium-cobalt electrodes. In addition, some startups recycle used batteries, advancing the circular economy.

Green Li-ion advances Lithium-ion Battery Recycling

Green Li-ion is a Singaporean startup that recycles lithium-ion batteries to produce battery cathode. The startup’s modular processing plants use co-precipitation hydrometallurgical technology in contrast to the conventional processes that use leaching reagents. This results in purity enhancement while reducing the production time of the rejuvenated cathode. Battery manufacturers utilize this solution for recycling batteries without the need for sorting.

Echion Technologies produces Lithium-ion Anode Material

UK-based startup Echion Technologies produces lithium-ion battery anode material for super fast charging. The startup’s anode material uses a proprietary mixed niobium oxide (XNO) technology which includes designing microcrystals with diffused lithium-ion. This enables fast charging without the need to use nanosized powders. Due to their high energy density, the applications of these anodes range from consumer electronics to the EV industry.

2. Lithium Alternatives

Lithium batteries are not environmentally friendly and it is hard to keep up with the increasing demand for lithium. These limitations are encouraging companies to look for alternative battery materials that power the next generation of battery storage. For instance, zinc-air batteries are a viable alternative to lithium given zinc’s abundant supply, inherent stability, and low toxicity. Another efficient alternative is sodium-sulfur batteries. These batteries feature longer lifespans, greater charge/discharge cycles, high energy density, and are fabricated of relatively inexpensive materials. Some other promising battery chemistries are aluminum ion batteries, magnesium ion batteries, nickel-zinc batteries, and silicon-based batteries.

7. Distributed Storage Systems

Energy generation and storage systems traditionally follow a centralized architecture. This increases grid failure risks during high energy demand periods, which may disrupt the energy supply chain. Distributed storage systems, on the other hand, address this challenge by allowing individual facilities to produce energy on-site and retain it for personal needs. Energy producers are also able to sell the excess energy to the grid. Distributed energy storage solutions such as EVs, microgrids, and virtual power plants (VPPs) avert the expansion of coal, oil, and gas energy generation. Moreover, they enable greater reliance on renewables through the integration of local energy storage solutions like rooftop solar panels and small wind turbines.

8. Solid-State Batteries

Conventional liquid electrolytes are highly combustible and have low charge retention and operational inefficiencies in extreme temperatures. To address these challenges, solid-state batteries replace the flammable liquid electrolyte with a solid compound that facilitates ion migration. Startups now use electrolytes like polymers and organic compounds that offer high ionic conductivity. Additionally, solid electrolytes support the use of high voltage high capacity materials for battery manufacturing. This enables greater energy density, portability, and shelf life. Since solid-state batteries offer a greater power-to-weight ratio, they are also an ideal choice for use in EVs.
