Welding Technologies for EV Li-Ion Batteries Market Outlook
The global welding technologies for EV Li-Ion batteries market was valued at USD 480.7 Million in 2021 and is projected to reach USD 1,182.3 Million by 2030, expanding at a CAGR of 10.5 % during the forecast period.
In a battery pack, hundreds of welds are required to make the connections of several components ranging from the cells to the terminals. Tabs and terminals are not only connected to busbars and collector plates, but also are required to connect to current collectors inside the cells. The welding technologies are used to increase the battery efficiency.
There are different welding methods used to make all the necessary tab-to-terminal connections including foil-to-tab and tab-to-busbar. These methods include ultrasonic bonding, laser welding, resistance welding. The welding technologies used in batteries depends on the requirements, such as the combination of materials and the tab thickness.
Welding Technologies for EV Li-Ion Batteries Market Dynamics
Major Drivers
Increasing demand EV vehicles across globe
Lithium-ion batteries are currently used in most electric vehicles due to their high energy per unit mass compared to other electrical energy storage systems. This type of battery also has excellent high-temperature performance, a high power-to-weight ratio, energy efficiency, and minimal self-discharge.
According to a report published by Global Electric Vehicle Outlook 2021, sales of electric cars including fully electric and plug-in hybrids was doubled in 2021 to 6.6 million.Additionally, EV Sales continued to grow rapidly in 2022 despite supply chain challenges, with 2 million electric cars sold globally in the first quarter of 2022, up by 75% from the year 2021.
There were around 16.5 million electric vehicles on the road worldwide by the end of 2021, which was quadruple the number in 2018. For instance, the number of electric car sales in China, made up about half of the global total EV sales in 2021, which is nearly tripled to 3.3 million.
Rapid adoption of EV battery laser welding process
Rapid adoption of EV battery laser welding process is expected to boost the market during the forecast period. The cost, quality, safety, and consistency of the battery are directly impacted by the prudent choice of welding techniques and procedures used in the manufacturing of EV batteries. The production process for EV batteries makes extensive use of the battery laser welding technology which is a cutting-edge welding technique.
In order to set appropriate welding process parameters for EV power batteries, it is necessary to choose the right laser and welding parameters based on the battery material, thickness, shape, and tensile requirements. These considerations include welding speed, waveform, peak value, and welding head inclination angle.
Existing Restraint
Rising safety concern regarding Li-Ion batteries in EVs
Rising safety concern regarding Li-ion batteries in EVs is expected to harm the market growth in the coming years. The usage of organic liquid electrolytes, which are volatile and combustible when operating at high temperatures, is the primary problem of lithium-ion batteries in electric cars.
Additionally, chemical leakage can also be caused by an outside force, such as a collision. A typical lithium-ion battery has an energy density of 150 watt-hours per kilogram unlike lead acid batteries or NiMH battery packs, which have an energy density of 100 watt-hours per kilogram.
Furthermore, lead-acid batteries require 6 kilograms to store the same amount of energy that a 1-kilogram lithium-ion battery can. However, lithium-ion batteries are inherently flammable and particularly sensitive to high temperatures. Due to heat, these battery packs typically deteriorate much more quickly than they would otherwise.
A lithium-ion battery pack that malfunctions will catch fire and can cause extensive damage. When the heat generation rate exceeds the heat dissipation rate, the safety issues with LIB almost invariably emerge as a local temperature rise, on which the temperature distribution (TD) in the cell has a significant bearing. It is highly challenging to detect although the TD inside the cell is the most reliable indicator of whether the cell is entering dangerous areas.
Emerging Opportunity
Technological advancement in welding equipment
There are two main types of lasers used in LBW applied to battery cells such as fiber lasers and pulsed Neodymium-doped Yttrium Aluminum Garnet lasers. The initial peak force of the pulse is greater than the average force as the laser energy is stored in capacitors before being released in pulses. Compared to lasers that emit continuous waves, pulses’ high energy is better suited to reflecting metals.
Due to the brief pulse duration, pulsed lasers generate less heat overall than continuous wave lasers. Therefore, a pulsed laser is preferable to a continuous wave laser for heat-sensitive components such as battery cells.Both Neodymiumdoped Yttrium Aluminum Garnet lasers and fiber lasers can deliver energy continuously.
The key LBW parameters include laser power, welding speed, and pulse rate due to their impact on the weld quality, weld bead shape, and weld dimensions. The dimensions of the weld zone are influenced by both laser power and welding speed. The difference is that welding speed has an inverse correlation whereas laser power has a direct correlation. The initial laser welding parameters can be carefully optimized to increase the weld quality.
The technique that is most effective for producing tiny weld nuggets is LBW. The current is constrained when the size of the weld nugget is less than that of the current. Limiting the current causes an increase in resistance and heat production when the battery is being charged and discharged. This reduces the battery cell's ability to perform in the long term.
