With the implementation of the new national standard, electric two-wheeled vehicle lithium batteries have started a "technological upgrade war".
Electric bicycles have become the absolute first choice for short-distance travel in China, with a staggering 350 million vehicles in use. However, while the industry is advancing by leaps and bounds, problems such as excessive speed and battery risks caused by illegal modifications have also buried huge safety hazards.
The horn of change has been sounded! In 2024, the "Safety Technical Specifications for Lithium-ion Batteries for Electric Bicycles" (GB 43854-2024) and the revised "Safety Technical Specifications for Electric Bicycles" (GB 17761-2024) were successively released, setting the direction for the safety and development of electric two-wheeled vehicles in the new national standard era. In this upgrade storm, lithium batteries, as the core driving force, undoubtedly stood at the center of the stage of "technical upgrading".

1. Safety touchstone: needle penetration test spawns a technological revolution
The new national standard has unprecedentedly stringent requirements for lithium battery safety performance. The "needle puncture test", which was included in the mandatory items for the first time, is even described as the "Mount Everest" in the field of safety. It requires that after the battery cell is penetrated by a steel needle and triggers a serious internal short circuit, it must not catch fire or explode.
This harsh test directly ignited the battle for the upgrading of lithium battery technology. Industry-leading lithium battery companies, such as BAK Battery, responded quickly and launched the PRO-M high-safety lithium battery series. This type of product is designed to conquer the "needle puncture test". Its core lies in the construction of a triple protection system:
(1) High-safety materials: The high-temperature resistant composite positive electrode material and high-stability electrolyte work together to effectively suppress the triggering of thermal runaway.
(2) Strong diaphragm: The composite coating greatly improves the heat resistance of the diaphragm and isolates the risk of short circuit under extreme conditions.
(3) Structural innovation: Through the optimization of conductive agents and foil materials, the overall stability and safety of the battery are further guaranteed.
This revolutionary lithium battery protection solution suppresses the risk of thermal runaway at the source, pushes safety performance to a new level, and builds a solid shield for the daily travel of 350 million users.

2. Performance Leap: Comprehensive Evolution Beyond Security
High-end lithium batteries under the new national standard are by no means just pursuing a single dimension of safety. They have achieved all-round breakthroughs in battery life, fast charging, temperature adaptability and cycle life.
Take the BAK PRO-M series as an example:
(1)Energy transition: The application of technologies such as high-voltage positive electrodes has increased its energy density by up to 17%, which directly translates into longer battery life.
(2)Extreme fast charging: The 46 series large cylindrical lithium battery supports 4C continuous fast charging and 4C discharge, greatly shortening the charging waiting time.
(3)Full-domain adaptation: The wide temperature range working ability from -30℃ extreme cold to 70℃ scorching heat ensures that the performance of lithium batteries remains as stable as a rock as the environment changes.
(4)Extreme life: The cycle life of the high-safety series 21700 and 18650 lithium batteries exceeds 1,000 times, and the 46 series large cylindrical battery reaches an astonishing 2,000 times, significantly reducing the cost of use.
High-performance large cylindrical lithium batteries are not only suitable for mainstream electric two-wheelers, but also have impressive expansion capabilities. In addition to electric scooters, electric motorcycles and balance bikes, they can also be extended to outdoor energy storage batteries, special security equipment and other broader safety application scenarios in the future. With the advancement of technology, various technical routes such as lithium iron phosphate batteries are also continuously improving their comprehensive performance to meet different market needs.
