There are many different types of batteries for electric motorcycles, including nickel-metal hydride batteries, lead-acid batteries, lithium batteries, graphene batteries, and black gold batteries. Currently, lead-acid batteries and lithium batteries are the most widely used in the market, while graphene batteries and black gold batteries are the products of further development based on lead-acid battery technology.
Batteries are essentially the fuel tanks of electric motorcycles. Old batteries for cars and motorcycles used to be lead-acid batteries, and the main weight of the battery was lead. Nickel-metal hydride batteries were popular for a while, and now the battery technology is lithium-ion batteries, which provide higher energy density and significantly better charging time than before.
There is a reason why lithium is popular - it is the third lightest element after hydrogen and helium, and has the advantage of being light in weight. It also provides considerable energy density, so for vehicles, it can fully meet the requirements. For motorcycles, the weight requirement is more important than for cars. Modern motorcycles are faster than many sports cars, mainly because they are very light. If they are matched with heavier batteries, performance will be weakened.
Over the past decade, lithium-ion battery technology has continued to advance, making electric motorcycles a viable option with enough range and power to provide an enjoyable riding experience, compared to the inherent limitations of current lithium-ion batteries.
Therefore, as the market continues to grow rapidly, further breakthroughs in battery technology are necessary if electric motorcycles are to truly compete with or even surpass gasoline-powered motorcycles.
At this stage, one of the most promising successors to lithium-ion on the market is still under development: solid-state batteries. Instead of using liquid electrolytes, solid-state batteries use solid ion-conducting materials such as ceramics or polymers. Solid-state batteries have several major advantages:
* Higher energy density: A huge advantage of solid-state batteries is their energy density, and solid electrolytes make it possible to use high-capacity lithium metal anodes.
* Faster charging: Solid electrolytes have higher lithium-ion conductivity, which allows for faster charging.
* Higher safety: No liquid electrolyte means there is no risk of fire due to leakage or overheating.
* Longer life: Solid electrolytes are less reactive with electrodes, which extends the service life.
Despite the many advantages of solid-state batteries, their high cost and complex manufacturing process have become two major challenges for their mass production.
In addition, solid-state technology still has a long way to go to catch up with current battery technology, and the most important issue is recycling. The recycling technology of lead-acid batteries is already mature, but the technology that can recycle lithium-ion batteries is not yet popular, which is also a problem faced by solid-state batteries. Many forecasts show that solid-state batteries will be seen in vehicles as early as 2025.
Therefore, a transitional technology has emerged in the market - semi-solid-state batteries. Its properties are between all-solid and all-liquid, with higher safety, higher energy density, longer life, wider temperature range, better pressure resistance, higher ion conductivity, and significantly lower cost than solid-state batteries. It can take advantage of the current lithium battery process to achieve easier mass production and lower cost. Only about 20% of the processes are different, so in terms of economic efficiency and industrialization speed, it is currently the best alternative battery before solid-state batteries break through the technical bottleneck.
