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.  

  1. 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.
  1. 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.
  1. 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.

Top 10 electric vehicle battery innovators

  1. Store Dot

StoreDot is an Israeli technology company that specializes in the development of fast-charging battery solutions, including a unique lithium-ion battery technology that uses nanomaterials and organic compounds. 

This technology enables significantly faster charging times compared to traditional batteries. StoreDot claims that their batteries can be fully charged in just a few minutes, which is a significant improvement over the hours required for conventional charging.

  1. Log9 Materials

Log9 has launched India’s first indigenous battery cell, TiB, based on Lithium Titanium Oxide (LTO) chemistry, offering enhanced safety, long life, low-temperature performance, and rapid charging.

Their RapidX series of batteries are built to be durable in tropical conditions, with an operating temperature range of -40° to 65° Celsius for up to 40,000 charge-discharge cycles.

  1. Nyobolt

Nyobolt's core technology revolves around solid-state batteries, aiming to address the limitations of current battery technologies, such as the risk of thermal runaway, limited energy density, and slower charging speeds. 

By utilizing solid-state electrolytes, Nyobolt aims to deliver safer, more efficient, and longer-lasting energy storage solutions.

  1. Faradion

Faradion is a UK-based company that specializes in the development and commercialization of sodium-ion battery technology.

Reliance New Energy Solar Ltd., a unit of Reliance Industries, has acquired a 100% stake in Faradion at a £100 million valuation, and is additionally investing £25 million more for accelerating the company’s sodium-ion battery’s commercial roll out.

  1. VSUN Energy

VSUN Energy, a subsidiary of Australian Vanadium Limited, has developed a vanadium redox flow battery (VRFB) that can deliver renewable energy in remote locations. 

It enables remote EV charging, with a VRFB being used to power an EV charging station, and provides substantial advantages for operating chargers in remote and high temperature environments.

  1. Manikaran Power Ltd.

MPL is an Energy Solution Company having combined experience and expertise of more than a decade in Power, Coal and Gas. In 2022, they announced an INR 1000 Crore investment in a proposed lithium refinery, to be set up at a cost of INR 2,200 crore for producing lithium hydroxide that is used in EV batteries.

  1. Munoth Industries Ltd.

Munoth Industries Limited (MIL) has set up India’s first lithium cell manufacturing unit with an investment of Rs 799 crores on a 30-acre site located near Tirupati Airport.

  1. TDSG

TDSG is India’s first Lithium-Ion battery manufacturing plant, established jointly in Gujarat by TOSHIBA Corporation, DENSO Corporation and Suzuki Motor Corporation.

  1. Amara Raja

The $1.3-billion Amara Raja Group, which has a significant share of the traditional lead acid battery market in India, has announced an investment of INR 7000 crores for Lithium-Ion batteries. Amara Raja has already obtained AIS-156 Amendment 3, Phase 2 certification from ARAI for its EV battery and off-board chargers.

  1. Attero Recycling

Attero bills itself as India’s largest electronic asset management company.Their process includes complete transportation and logistics related to recycling li-ion batteries, along with their safe destruction and full recovery of the metals that can be reused.
