2025-11-21 22:59:01 EVE Energy launches its new all-tab cylindrical battery, propelling tool lithium batteries into a new era of high-rate performance!

On March 24th, the 38th China International Hardware Fair grandly opened at the National Exhibition and Convention Center in Shanghai. As the largest and longest-running industry event in the fields of hardware, electromechanical products, power tools, and garden tools, this year's exhibition attracted over 3,000 companies from the global industry chain. Driven by the trends of "cordless" and "lithium battery replacement," the global power tool market is growing at an average annual rate of 9.2%, approaching a scale of hundreds of billions (data source: Frost & Sullivan). However, the gap between battery performance and end-user demand persists—insufficient power, range anxiety, and short lifespan have become key bottlenecks restricting the penetration rate of lithium batteries in power tools.
