While lead-acid batteries may not be suitable for long-range electric vehicles, they can still be effective in electric vehicles that are primarily used for short-distance travel or in specific app.
Some do-it-yourself conversion kits for electric vehicles also use lead acid batteries. Lead acid batteries are comparatively heavy—and dangerous because they contain lead, which is toxic, and sulfuric acid, which is a hazardous material.
In the future there may be a class of battery electric automobile, such as the neighborhood EV, for which the limited range and relatively short cycle life are sufficiently offset by the low first cost of a lead–acid design, but for all vehicles with a range between charges of over 100 miles or 160 km, lithium-ion batteries will be needed. 5.6.
Lead acid batteries are commonly used to provide startup or backup power in gasoline- and diesel-powered vehicles. In addition, lead acid batteries have often been used in many special-purpose vehicles, including fork-lifts, low-speed utility vehicles and golf carts.
Lithium ions provide higher energy and power densities and better energy efficiency than earlier battery systems. This makes them the battery of choice for many plug-in vehicles planned by major automakers. Taking advantage of this, the Tesla company uses thousands of lithium-cobalt-oxide cylindrical batteries in its battery electric sports car.
Lead-acid batteries are widely used as the starting, lighting, and ignition (SLI) batteries for ICE vehicles (Hu et al., 2017). Garche et al. (Garche et al., 2015) adopted a lead-acid battery in a mild hybrid powertrain system (usually no more than 48V) after improving its dynamic charging and discharging performances in 2015.
On contrary, lead is a carcinogenic material that is harmful to the environment. Even lead-acid batteries contain other chemicals such as sulphuric acid that are poisonous. But the recycling rate for lead-acid batteries is higher than Li batteries. Also, lead-acid batteries are cheaper because of their wide availability.

Researchers at Stanford University's Precourt Institute for Energy and SLAC National Laboratory have shown that an average electric vehicle (EV) battery could last 40 percent longer than.
The new findings, published today in the journa l Nature Energy by researchers from the SLAC-Stanford Battery Center, suggest EV batteries may actually last about a third longer than previous forecasts. That means drivers could potentially keep driving their modern EV without replacing the battery for several additional years.

But experts from Stanford University have found the opposite is true for electric vehicle (EV) batteries. Their new research shows traditional laboratory testing leads to faster degradation, while real-world use gives substantially more battery life, extending the lifespan of the entire EV.
The Stanford study says this is producing misleading results. “Real driving with frequent acceleration, braking that charges the batteries a bit, stopping to pop into a store, and letting the batteries rest for hours at a time, helps batteries last longer than we had thought based on industry standard lab tests,” said Onori.
Not only does stop-and-go driving extend the life of EV batteries, the spurts of acceleration and braking also mitigates degradation. What now?
That's why some experts call solid-state batteries “forever batteries.” And that's why these forever batteries are the key technology to accelerate the EV Revolution to the next level.

The capacity of a lead–acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert's law.
This article describes the technical specifications parameters of lead-acid batteries. This article uses the Eastman Tall Tubular Conventional Battery (lead-acid) specifications as an example. Battery Specified Capacity Test @ 27 °C and 10.5V The most important aspect of a battery is its C-rating.
The lead acid battery maintains a strong foothold as being rugged and reliable at a cost that is lower than most other chemistries. The global market of lead acid is still growing but other systems are making inroads. Lead acid works best for standby applications that require few deep-discharge cycles and the starter battery fits this duty well.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
According to a 2003 report entitled "Getting the Lead Out", by Environmental Defense and the Ecology Center of Ann Arbor, Michigan, the batteries of vehicles on the road contained an estimated 2,600,000 metric tons (2,600,000 long tons; 2,900,000 short tons) of lead. Some lead compounds are extremely toxic.
In 1992 about 3 million tons of lead were used in the manufacture of batteries. Wet cell stand-by (stationary) batteries designed for deep discharge are commonly used in large backup power supplies for telephone and computer centres, grid energy storage, and off-grid household electric power systems.
Lithium-ion batteries have significantly higher energy density, ranging from 150-300 Wh/kg, compared to lead-acid batteries, which average 30-50 Wh/kg. This makes lithium-ion the preferred choice for portable and high-performance applications, while lead-acid batteries remain useful for affordability and reliability in non-portable settings.
In 2024, the global lithium-ion battery market reached 1,545. 5% increase from the previous year. LFP batteries are now seeing strong demand outside China as well, particularly in Europe and North America.
As a result of this trend, TrendForce expects the cost-effective advantage of lithium iron phosphate batteries to become more prominent and this type of battery has an opportunity to become the mainstream of the terminal market in the next 2-3 years.
TrendForce indicates, from the perspective of the world's largest EV market, China, the power battery market reversed in 2021 and lithium iron phosphate batteries officially surpassed ternary batteries with 52% of installed capacity.
Lithium iron phosphate (LFP) cathode chemistries have reached their highest share in the past decade. This trend is driven mainly by the preferences of Chinese OEMs. Around 95% of the LFP batteries for electric LDVs went into vehicles produced in China, and BYD alone represents 50% of demand.
According to TrendForce investigations, planned expansion projects announced by global cathode material manufacturers are currently concentrated in China and South Korea, with a nominal total planned production capacity of over 11 million tons, of which planned production capacity of lithium iron phosphate cathodes accounts for approximately 64%.
You have full access to this open access article Lithium iron phosphate (LiFePO 4, LFP) has long been a key player in the lithium battery industry for its exceptional stability, safety, and cost-effectiveness as a cathode material.
Two materials currently dominate the choice of cathode active materials for lithium-ion batteries: lithium iron phosphate (LFP), which is relatively inexpensive, and nickel-manganese-cobalt (NMC) or nickel-cobalt-alumina (NCA), which are convincing on the market due to their higher energy density, i.e. their ability to store electrical energy.
