Electric vehicle battery technologies and innovators

All roads in electric vehicle technology and design lead to the battery, so it’s no surprise that most of the research in this industry is focused on the battery. There’s intense competition between BEV and hydrogen fuel-cell vehicles, and even in terms of the battery technology that will provide faster charging, cost less and increase battery life.

In this post, we take a look at the top 10 electric vehicle battery technologies and innovators that may come to replace traditional lithium-ion EV batteries.

Electric vehicle battery technologies

1. Lithium-Ion variants:

a)Solid-State Batteries: Solid-state batteries replace the liquid electrolyte in lithium-ion batteries with a solid electrolyte. This improves safety, energy density, battery range and charging speed.

b) Lithium-Sulfur Batteries: Lithium-sulfur (Li-S) batteries use sulfur as the cathode material. Li-S batteries can significantly increase EV driving range and reduce the battery cost, since sulfur is more abundant and environmentally friendly than other metals.

c) Silicon Anodes: Silicon, with a higher energy storage capacity than graphite, could replace graphite anodes. EVs can provide longer ranges, shorter charging times, and be more cost-effective.

d) Graphene: Advantages of using graphene in EV batteries include high energy density, faster charging, longer cycle life, and it is a lightweight and ultrathin material. Reducing the battery weight is one of the toughest challenges for battery and EV designers. However, graphene has its own challenges in terms of manufacturing, scaling, and concerns of stability and safety over thousands of charging cycles.  

2. Sodium-ion Batteries: Sodium-ion batteries are now available as a cheaper alternative to lithium-ion batteries. The energy density of sodium-ion batteries is lower, but it reduces the cost of battery production, increases its accessibility, and has a reduced environmental impact compared to lithium-ion batteries.

3. Aluminum Air: Aluminum-air cells are a type of metal-air battery that use aluminum as the anode and oxygen from the air as the cathode, with water or an electrolyte solution serving as the electrolyte. Advantages include high energy density, refuelability, and lighter overall weight compared to conventional batteries.

4. Flow Batteries (Redox): Flow batteries use two electrolyte solutions separated by a membrane. The advantage is longer range and rapid charging (by replacing the electrolyte), but that is offset by the larger size of the tanks required and the weight of the batteries. Flow batteries are also being used for providing charging stations in remote and high-temperature environments.
