Electric vehicles, commonly referred to as EVs, have quickly evolved to be a part of the global electric transportation system, seamlessly integrating electric propulsion and power storage systems. EVs has shifted the fundamental approach and the need of transportation today. Mass deployment of EVs has been hindered by a single factor, the anxiety of range. There is a persistent concern about whether electric vehicles would be able to get to the destination without running out of charge and the problem of availability of charging stations, especially on long-distance trips. Next generation, single charge capable EV Batteries, set to be capable of 1,000 kilometers on a single charge, would help alleviate this issue. Fundamental changes in lightweight construction materials, energy density, battery life, charging speed and other factors also sustainable, would be core to this channeling transformation of mobility.
The Evolution of EV Batteries
The history of EV batteries has focused on storytelling the development:
Lead-Acid to Lithium-Ion: The slowest stages of development for any electric vehicle is the propulsion construction phase. Slowly, the world began to realize the need for smaller, lighter and more efficient batteries for electric vehicles and the evolution of the heavy lead-acid batteries. The introduction of light, high energy rechargeable lithium-ion batteries was and is a revolution.
Advances in Chemistry: The introduction of lithium batteries has greatly accelerated the advancement of anything and everything electric. The past few decades have witnessed leaps in development in NMC and lithium batteries.
Solid-State Technology: Currently, automakers alongside battery manufacturers are in a heated chase towards replacing liquid electrolytes in solid-state batteries with entirely solid electrolytes. This change can lead to solid-state batteries having higher safety, faster-charging, and larger range.
Given these breakthroughs, EVs which once struggled to achieve a range of 200 km could soon offer close to five times that range, thus making these EVs far more practical for a variety of travel purposes.
What Enables 1,000 km Range in EV Batteries?
The jump to 1,000 km is not due to a singular groundbreaking achievement, rather to a multitude of advancements in technology:
- Higher Energy Density
The batteries of next generations are able to fit and pack more energy in small and light cells. Advances in Solid-state batteries and silicon anodes are able to achieve to storage capacities that were once termed to be impractical. - Advanced Battery Design
Companies are embracing cell-to-pack (CTP) and cell-to-chassis (CTC) designs, which drastically remove module weight and integrate excess batteries directly into the vehicle frame. - Ultra-Fast Charging
Some next-gen EV batteries are expected to charge from 0% to 80% in less than 15 minutes, making long-range EVs very practical as ultra-convenient vehicles. - Enhanced Durability & Lifecycle
The next-gen EV batteries are expected to last 1 million kilometers with minimal degradation.
Sustainable Materials
Long-range electric vehicles (EVs) will not compromise on their environmental integrity, due to the demand for cobalt-free batteries and advancements made in battery recycling.
Global leaders driving the next-gen battery race:
There are many car manufacturers and battery companies working tirelessly to make 1,000 km range EVs a reality:
Tesla: Working on 4680 high-energy cells and new battery chemistries to increase range.
Toyota: Working on game changing solid-state batteries, with massive anticipated improvements to EVs by late 2020s.
CATL (Contemporary Amperex Technology Co. Limited): Mechanical and electrical engineer of the world’s largest EV battery. Recently battery electrodes for 1,000 km range vehicles.
BYD: Advanced extensive safety and energy dense Blade Batteries.
European Innovators: Northvolt and other companies are building gigafactories to meet the increasing demand for sustainable batteries.
All of these advancements being made towards 1,000 km EVs show that they are no longer in the conceptual stage, and are on their way to commercial production.
Increased mobility for the population with the introduction of ultra-long-range EV batteries will change the entire mobility ecosystem:
- No range anxiety
Long drive trips without the concern of charging stations will be a reality for drivers.
- Increase in Use of Electric Vehicles
People considering converting to EVs primarily because of range anxiety issues would consider EVs with range of 1000km as plausible replacements to conventional internal combustion engine (ICE) powered vehicles.
- New Opportunities for Fleets and Logistics
Trucks, buses and ride-sharing networks will lower their operational costs and downtime with extended range vehicles.
- Less Dependence on Densely Placed Charging Points
Longer ranges will reduce public charging to the point of negating its use, public charging will no longer be a bottleneck for expansion of the network.
- Increase in Use of Renewables
Rectangle next-generation batteries will support vehicle-to-grid (V2G) systems to allow EVs to provide a service for the grid for storing excess renewable energy and for grid stabilization.
Obstacles on the Way
However promising, a few difficulties need to be addressed for 1,000 km EV batteries to become mainstream.
Cost: Next-generation batteries with advanced chemistries and components will be expensive to produce, at least in the early stages.
Scalability: High volume manufacturing with acceptable standards of quality, and sustainability is a challenge.
Safety: Solid state and other new technologies must achieve a set of rigorous safety standards.
Infrastructure Readiness: There is a need for ultra-fast re-chargers to support rapid re-charging.
These challenges must be addressed collaboratively by automakers, governments, and energy providers.
Industry Outlook
Experts believe that by 2030, Electric Vehicles (EVs) priced within the premium segment and used for long-haul driving will have 800-1,000Km range battery capabilities, and widely used. Production of long-range EVs will become more affordable and accessible to the mass market as the production scales and costs decrease. Global approaches that support decarbonization and more stringent emission regulations will use the next-gen batteries as the foundation of sustainable EVs.
